Hi, can someone help please, got a 54 plate Mondeo 2 ltr tdci engine blew so put in engine out of a 2006 model, put on my old turbo, vacuum type, put in my old cam sensor and flywheel sensor plus fuel rail pressure switch, new fuel filter, cleaned egr valve and working ok. The problem is struggles to start, when it runs, runs perfect, drove it approximately 40 miles no problems, no fault codes showing but when I stop the engine just will not start. It appears to only start when engine is cold although does try to start when warm but never catches.


The fuel pump and injectors are the ones out of the new engine they have not been disturbed at all. We seem to have good fuel rail pressure when running at about 3000 rpm its up to about 15000 psi but just at a loss as just why it won't keep running.


Any help or information would be greatly appreciated.

 

do leak off check at injectors as a base starting point plus the pipework...you could substitute your old ones if known to be good-need coded though-but if you have technology to read the rail pressure you can probably do this

 

hi tony66 thank for reply do you mean crack off leak off pipes when warm to check for fuel being returned ? I will try today is there a electric cut off switch on theses that might not be returning to run ? can you say what I would need to do to re code injectors and pump or would putting my old injectors in that should be compatable with my ecu do it ? had good check round for air / fuel leaks couldn't find any many thanks ek54

 

If you havnt coded new injectors to the car then this will be the problem. You can either swap your old injectors to new engine ( but must stay in same cylinder removed from) if you cant recode or simply code the new injectors to the car.

 

thanks for that 1980 blakey
will try swapping injectors are you able tell me step by step how to re code injectors or is there a link explaining as ive never done it before
the code reader I go is a Clarke EOBD engine fault code reader do think this any good for the job many thanks ek54

 

you can get the ford vcds package online around Ł20 ish you can code with this

in reality if you use the injectors you know to be good in the correct order[as previous] it should be fine
leak off is when running-if it returns too much its furbar,should all be even within given tolerance[do into 4 wee jars at same time-any difference becomes obvious

 

hi just put old / original set of injectors in piped up, just winding car over to get fuel up to injectors fuel spouting out of metal pipe on injectors but not yet firing will keep trying and keep you informed many thanks ek54

 

any ideas how long we have to crank these engines over to get them to fire when we have swapped injectors been at it a good hour but nothing tried helping by putting air line over fuel cap cracking injector pipes many thanks ek54

 

shouldnt be hard to start at all-few seconds and should splutter into life providing fuel pump good,filter full-no leaks etc
you have an issue somewhere...

 

Hi, got a hand primer of a Peugeot pulled fuel up into filter, then cranked over on the key with fuel return off into a tin no bubbles or debris. Reconnected return pipe turned it over to try and start It was trying to fire but didn't catch. Had the jump leads on to another car to keep voltage up but still wouldn't fire even though it was puffing some smoke out of exhaust. Swapped cam sensor for a grey one just in hope but no luck. Plugged in fault code reader and it came up with the code P0251 - injection pump fuel metering control A malfunction (cam/rotor/injection). I also checked live data when cranking and fuel pressure was up to 5600 ish psi. Any ideas how we could get this running?
Many thanks

 

near your fuel filter there is a red tagged return pipe that connects to the main return to the tank, you need to drag the fuel through from the return, once there is plenty of diesel coming out of the pipe your system is bled.

 

bottom right, disconnect the red connector and drag fuel from the black plastic pipe, you may need to adapt something to get a good fit and seal, when loadsa diesel comes through you should be fine, if of course your only fault is a big gulp of air in the system.

 

hi thanks for that info had a go to day got maybe 1 ltr through of diesel turned over started to fire but not catch then battery failed so put on charge will try again in morning many thanks ek54

 

hi all bled fuel through return pipe as studabear recommended had about 4 ltrs through seems to have cleared air hand primmer then gose tight and wont pull any more fuel done this with ignition on and off when turning over it trys to fire and getting grey smoke from exhaust but wont run tried swapping cam senser and fuel rail switch but no joy also its not showing any fault codes has any one come across this problem any hint l would be greatfull many thanks ek54

 

you tried towing it?

 

not since it was running last it did start on key when cold but not when warm some one said it needed original injectors to match up with ECU so swapped in right order so did that, didn't want to damage cam chain by towing

 

has anyone ever herd of anyone being able to fix this bad starting problem I did take it to my local garage and he said sorry mate cant do any thing don't no whats up with it, but it was such a good car I don't want to get rid of it so will keep trying ek54

 

driving along in 6th gear suddenley lost drive to wheels jacked up nearside wheel put in to gear turned wheel it seems to be ingauged but not when on ground any ideas of problem please its had d m f conversion 7months ago was ok before lost drive

 

did you get the starting issue sorted?

 

sort of took to a fuel injection place and they found that injectors were siezed and not opening so brought home and not looked at it since the clutch problem is on my sons mondeo didnt really want to start taking engines gearbox out again

 

I would scrap it and cut your losses, sounds a uneconomical repair.

 

yer thats the plan got another car just havant got round to advertising it when we get clutch sorted on sons car thats going and no more mondeos in the drive
