Urgent help needed with 02 Mondeo ST220
Discussion
Hi Guys could do with some help, bought an 02 st220 8months ago, ran perfectly, then around 3 weeks ago wouldn't start, took it to mechanic friend had it on diagnostics it said coils, changed the coils, started for a few days then wouldn't start again, back to the garage,changed crank sensor,new plugs,filters (generally serviced)still didnt work. So then back on diagnostics it came up the ECU? took it to a better diagnostics guy, who said that the ECU was telling the injectors that it was colder than what it was so the injectors were putting to much fuel through, so options were to reset the ECU to put less fuel in or new ECU! we tried the resetting, the car started everyday but not very well, so took it back and had the ECU sent off for 'special test' which has come back today with nothing wrong with it? so we are at the point where our friend is telling us to send to ford, we're scared because we can see the bill esculating....Help please..
Coolant temperature sender or one of the possibly 2 thermostats has gone
Ford charge £70 odd for a diag, unless you've got the s/w to decode the protocol the ECU is using, you're better off going to Ford. Half of the diag messages you get by pressing the trip meter are worthless
PS - to reset the ECU, just disconnect the battery for half an hour. But that wont fix a faulty sender/sensor

Anyone with a half decent diag machine can read the live data on the ecu, from that you can check what the coolant temp sensor is telling the ecu as well as the o2 sensors, fuel pressure timing, crank angle etc.
That should be the first place to look as if there are any odd readings theres your fault. It seems the place you have taken it is using a "lets change that and see if it works" which can be a very expensive way of doing things.

Thanks for the other info guys but looks like the garages we have previously had it in were way off...took the car into Camco at Warrington, Cheshire and they have checked the car out...heres what they have come up with....car is only firing on 2 cylinders, spark plugs 4 & 5 are drenched with water, water tank is massively pressurised they say that its all pointing to head gasket failure...they said that they took the manifold off and sparks out, turned it over and water was splurting up soaking the spark plugs...they have quoted £2500 + VAT....on an 02 reg its just not worth it is it.....they did say it might come in around £1500 + VAT but chances are its gonna need more work.....we just don't know what to do....does anybody have any suggestions....please help.....
Firing on two cylinders?! It would have run like a dog if at all. 4 & 5 have water, so which out of 1,2,3 & 6 is firing? What about the two that aren't full of water but have no spark? HG failure is common on the 2.5's but i have never seen one go through the water jacket. Is this place trust worthy?
Cheers, this is what I can't work out at all...when its running its running well, as you have probably guessed i'm not well up on the working of cars..but drives lovely and sounds great....its just the getting it started issue, I was convinced that it was to much fuel going in, that would make sense....long story but got it back last Tuesday, started Wed and Thurs then not friday....got the RAC this Tuesday to get it to the garage and they finally managed to start it by taking the fuse out of the fuel pump?? its had an oil change recently and no tell tale signs and the water level is not going down any faster than what I would expect....the only thing is it does blow slightly white smoke from exhaust....anyway just told the garage to wrap it up, gonna have to get a second opinion i think....
I'd run out of there, make sure you get the quote in WRITING as it sounds like they are out to shaft you(may come in handy in the future
). If it's pissing coolant from empty spark plug holes then it wouldn't run at all, and the coolant level would be down. White smoke from the exhaust is normal. Do you have a half decent Ford gagarge near you? If not where are you?

If not where are you?Hi,never used ford garage, I was going to use the one at Trafford Park, Manchester....but we would go anywhere in the NorthWest area...we really don't know what to do...we are thinking of cutting our losses and trading in but we are going to lose thousends...you sound like you know what your talking about what do you think? is it worth spending another £100+ quid at ford? we have spent around £650 in the last month....
I would REALLY want a second opinion on this! There is no way you could have missed 2 cylinders being full of water! If it runs like a dog when you pick it up, then I would be damn sure that the garage have massively abused it in some way! If the coolant system were that pressurised then the vent cap on the header tank would have been steaming, nay, gushing away.
As others have said, it just wouldn't have run with only 2 cylinders firing.

Is Chester a million miles from you? I have a good m8 who is a Ford tech, infact thinking about it they have a dealership in Manchester, i'll drop him an email tomorrow and see if there is anyone who he can recommend. I'd say it was deffo worth looking at as what you have been told just doesn't stack up IMO. I wish you were closer as i'd love a look at it!!
Really sorry guys I made a mistake its not firing on 2 cylinders rather than only firing on 2 cylinders....im guessing it would still run like a dog though only firing on the 4....and its 4 & 5 not firing...water is pressurising ...but no water in the header tank...when the plugs were out there was water coming out of the bores....(really sorry again, i'm just not mechanically minded, i phoned my mate who's a mechanic who phoned Camco for me this morning and he explained things better to me, camco baffled my head, felt like they may have been doing this on purpose though...my mate did also add if they are telling the truth!!)....thanks for the advice and wish i was closer to you....i just dread picking it up tomorrow and it not running like it was....Chester isn't a million miles away so if its running ok i could get it there but if its not i'd struggle, honestly though it was running perfect my mate even took it for a drive last week and was like wow....
If there that much water pouring in the engine i would have expected it to be hydraulic locked and would not be doing anything at all. If it really is that bad though your best cutting your losses and replacing the engine. Its a big job to remove the heads on your engine (it's an engine out job)and even if they do the head gasket the bottom end may well give up shortly after. I put an engine in a st200 about a year ago and the total job was about £2500 so if your considering paying out that sort of money better off having a brand new Ford engine because at least you will know its all good and you will get a good warranty.
And if it is fubar drop me an email, i may be interested in taking it if the ££ is right and Ford don't charge silly money for the engine! I did think hydro locked but if is is pissing water out like that then the gasket has gone and the pressure will go into the expansion bottle(which should let it it when it reaches a certain point).
