Ford Focus starting problems, car just won't start

I have a 2006 1.6tdi sport Ford Focus the oil pump failed causing the engine to wreck. I have replaced the engine but the car refuses to start or turn over? Different versions depending who you ask are. The brain has to match the key and the fuel pump? Anyone had this problem?

i have a focus tdi 1550 and i am getting fuel or eletric problems with it . as i drive it it feels like ther is water in the fuel you put yor foot down and it will not go no power then it will suddenly go and will blow black smoke just a bit. and when you coast it feels like it is misfireing does anyone know wats causing this problem?

Had same problem, there is a connection for the fuel pump under the back passenger seat, drivers side, there is a bung with a wire going into it, pull the bung out and fiddle about with the connection clip whilst someone is trying to start the car up, if no joy the clip may need replacing, the fuel tank would have to be dropped for this, or u cud just do the work from inside by cutting into the metal then soldering back. Hope this helps :)

can anyone help me got a ford focus 1.6 petrol 2000 my car will not start turning over and has fuel going to pump the aa said its the fuel pump but had that replaced about 6 months ago they also said i only had 4 volts instead of 6 which is what i need

I have had the same problem an a customers car, Ford main dealers had not got a clue when I phoned them for technical advice, They told me that they had several 1.8 Tdci with this problem,My diagnostics said it was the crankshaft sensor so I fitted a new one cancelled the code, And guess what the same code came back and the engine still would not start,So after racking my brain, I decided to try different things,And the result was faulty EGR valve, When I UN-plugged the EGR valve the engine started up straight away, My local Ford Dealer was very pleased when I called them to tell them that I had cured the starting problem.

"Does anyone have any idea what this could be?"

Rough guess, it's screwed.

Hi, I have a 1999 Ford Focus 18TD. Driving home from work it started to lose power until it finally came to a halt. I waited and after it had cooled, checked the oil and water. This was fine. I tried starting it up again and it started but a huge plume of black smoke belched out of the exhaust. I tried revving the engine. No more black smoke, but the engine was rattling and making a noise like metal on metal, a sort of squealing. Also, I could smell something burning. Only very slightly though. Does anyone have any idea what this could be?

Most diesel starting problems stem from three sources: 1. Lack of or poor delivery of fuel. 2. Faulty glow plugs. 3. Lack of cylinder compression.

Lack of fuel can be caused by a wide range of faults, the most common being a blocked fuel filter, air in the fuel system, poor pump pressure and faulty injectors. A clean looking fuel filter may not appear to be blocked, but if you haven't replaced it yourself before, put a new one in to be certain. You'd be amazed at how many garages don't change these filters at a major service. Make sure the filter seals are renewed at the same time. Air leaks can be hard to track down, but you should be able to tell if you have one because, due to syphoning, there will be little or no fuel forward of the low pressure pump when you first try to start the car, also there may be bubbles present in the fuel line when the car initially starts. They may persist while the car is ticking over if the leak is particularly bad. Almost any part of the fuel system can spring a leak, so tracking it down takes time and patience. Start at the fuel tank and check every seal and pipe joint all the way forward to the injectors. Odds are somewhere along the line you will come across a badly seated O-Ring or loose pipe nut. Unless the leak is really bad you won't see any diesel coming out, it's a fairly viscous liquid and can't always pass through pathways air can travel through easily. If there is no obvious leak, you may need to have the system pressure tested by a diesel specialist. Have the pump efficiency checked at the same time. Don't go to a main dealer, they are worse than useless at diagnostics, plus a specialist will have more experience of other issues that may have effect your particular cars fuel system. If there are no leaks and your pump's fine, then you may be looking an injector problem.

Unliike petrol injectors, diesel injectors work at very high pressures, especially in common rail systems, this means they are more complex and more expensive to manufacture. It also means they are more prone to failure. Most failures are caused by blockages or wear and result in an injector delivering fuel to the cylinder poorly or not at all. Without the right equipment you cannot diagnose injector problems, other than complete injector failure. This would be apparent, because white smoke (not steam) would be billowing out of the exhaust, accompanied by a strong diesel odour, and/or the engine would be very rough. If you suspect the injectors there are a large number of specialist firms that can test them and diagnose any faults, they may even be able to refurbish them for much less than the cost of a new replacement.

At engine start-up glow plugs preheat the air and fuel mixture in the combustion chamber (cylinder) before it is compressed by the piston. This aids the ignition process, after which the glow plugs should not be required except in unusually cold conditions. Faulty glow plugs are not uncommon, but are not easy to diagnose without testing them and their relays electrically. If they are easily accessible, you could remove them and test them with a car battery to see if the tips heat up correctly (they should glow white hot). A faulty plug may not reach sufficient temperature or may heat up at the wrong point on the plug, making them useless. WARNING: Severe burns can result from touching a recently active glow plug. Glow plugs are not expensive, so replacing them yourself could be a cost effective solution to your problem.

Finally, good cylinder compression is a vital component of a diesel engine, without it combustion leaks will occur and this will effect engine starting quite severely, particularly when the engine is hot. An engine may not appear to run roughly even with lowered compression, but it will be less fuel efficient and will likely burn engine oil (blue-black exhaust smoke is the most common evidence). Due to the very high pressures involved, compression testing equipment for diesel engines tends to be quite expensive, so it may be cheaper and easier to seek the help of specialist. A quick, and not very accurate, compression test can be achieved by squirting a small amount (teaspoon) of engine oil into the cylinders via the glow plug ports when the engine is hot, then replace the glow plugs and start the engine. If the engine starts easily there is a good chance you have a compression problem, if not start looking elsewhere. Poor compression can only be remedied by an engine rebuild or replacement.

One last possibility is a blown head gasket. With high compression engines even a tiny breach in the gasket can result in huge losses of pressure in the cylinder and poor starting could be a symptom.

Hope some of this helps.

i have a 1999 tddi focus. replaced diesel pump and got it fired up by using easy start. car run for 10 minutes and then stopped and refuses to start. any ideas??

I took a look at my engine compartment fusebox...im missing R166, R34, F3, R167/285 (taken from Haynes manual) they all have the icon of the heater plug in a water bath? Could this be anything related to my problem?

What would cause my 02 focus TDCI to intermittantly not start? she cranks fine but refuses to fire and the glow plug light flashes. Then I turn the key to off and back to on (glow plug light no longer flashes) and she starts on the button no bother. Are there any sensors or relays that could be causing this? No other symptoms such as stalling, poor fuel consumption, rough idle etc. Just the random embarassing ignorance of my car :/ it usually happens when ive drove for a short distance and try to start it a few minutes/hours later, but its really difficult to identify any pattern! any ideas much appreciated

These Engine management lights, and diagnostic fault readers are just an excuse for manufacturers to rip us off. Did they not inform you of the cost before they carried out the work?. Id have told them to stuff it cuz they are out to rip us off all the time!!!!. I had problems with my car starting. My mechanic checked the engine diagnostics. He said the glow plugs needed replacing and charged me £100. Strangely enough a month later i started having exactly the same problem with my car, in that it wouldnt start correctly and the Engine management light stayed on. Of course my glow plugs would still have been under warranty so the mechanic told me that my glow plugs were fine and that this time it was another problem which would cost me £50. Its my theory that the first time he only renewed 2 glow plugs (although he charged me for 4), and subsequently the other two later died on me. It's rampant in the motor industry. I bet hundreds if not thousands of people are ripped off each week!!!

Hi Ben thanks alot for the tip will try that and see if it helps. Kind Reguards Gary

problems with starting ford focus 1.8 tdi.gary. similar focus estate 1.8 endura 2000.try taking 3 fuel filter pipes off fuel filter.(under bonnet) pour fuel into largest hole at front, untill full (diesel).check "o"rings for damage. also pour fuel into pipe leading to injection pump for injectors.reconnect fuel pipes locking into place.make sure at each step. we did this and after a couple of longest turns of key engine picked up. drove 150miles on motorway ok.still ok. car had stood 2 days , think diesel fuel had syphoned back into tank.perhaps worn "o" rings .

Ive had problems for 5 years from my 1999 1.8 tdi focus. From the first week i bought it theres been nothing but problems starting it . It verys from day to day it wont start just keeps turning over with white smoke coming out of it. ive tried heater plugs fuel treament etc. took it to ford nobody has ever been able to find a problem. Would anyone recommend anything. GARY

I am currently having the same issues with my 2009 ford focus and i am soooo irritated as well luckily i have taken it in they still havent fixed things on it m=but i havent come out of pocket YET!

Just to let you know that my daughter's focus is still running brill as at Nov 26th. If anyone still having problems in north notts area I can put you in touch with someone who may help.

to the person who did not rate my comment, I was trying to help others not to fall into the same trap as we did, we could prove costly. I could have gone into a lot more detail but tried to keep it as short as possible. It would appear that there is a lot of guess work into curing this problem. Like I told one garage "I could keep changing parts until I got the right one" My daughter's problem was car not starting after a short journey with glow plug light flashing, if you turned it on and off a few times the light would go out and it would start. Although the problem would only appear when the car was cold it was not a cold staring problem. When you did manage to get it started you had to keep revs on until it warmed up and it would not rev past 3000rpm. I would definately try a reputable auto electrician first. Hope this helps more.

The main problem is that the glow plug light also acts as engine management. Also, a poor start problem can be a number of issues so you need to know what, that's the problem. My daughter's 2002 1.8tdci has just been fixed for a starting problem after a short run. The car has been attached to diagnostic units five times at three different places and no faults recorded until third attempt. I was told it wanted this, that and the other in excess of £1200.00. Then I was informed it needed a battery (which is still on the vehicle and working fine) and that was the problem! this was by diesel specialists. Eventually it went to auto electricians, who have a ford diagnostics m/c, who appear to have cured the fault but don't know what they have done. They suspect fautly wiring on the ecu which they removed and put back. £126.00.

Injectors reprogrammed, apparently they were "leaky" which was the cause of the black smoke. No smoke now thankfully, egr valve is fine. As for the starting issue, the light goes out far too quick and I just need to wait 10 seconds until I hear the click and the heater fan momentarily dips. Problems solved for anybody in the same situation as me. Hopefully I wont have post here again!
