My escort has been running badly for about a month now and i cant work out what it is. It runs fine until it warms up and i switch it off and then it wont tick over and it misfires badly, i think this is the ecu safe mode when it knows theres a fault but im not sure, if the car is left for a bit then it will run fine again. Once its been ran the fuel pump stays on permanently when the ignition is on and the cars not running.

Ive changed nearly every sensor apart from the air temp sensor and the boost controller under the slam panel, ive taken out the fuse box and everything looks fine & ive cut out the 2 multiplug connectors in the engine bay and soldered the wires together. Ive checked the ecu connector and it looks fine. Ive tried a different fuel pressure regulator, ive also had the car plugged into a ford diagnostic tester and it showed no faults but the car wouldnt play up when it was there.

Ive ran out of ideas now, just wondered if anyone else had come across anything like this before.

Please Help!!!!!

 

Is the ecu chipped?

 

no everything is standard

 

Sounds like some heatsoak problem, I'd guess at EDIS or ecu. What's the catch code of your ecu?

 

where is the catch code? i tried an ecu from work but it has the pats system so it wont work without the key

 

ive tried an edis module too

 

It's on the label on the ecu loom connector.

 

MR LEWIS
mine is exactly the same and it cuts out when warm and over fuels it runs like a bag of shit. please hel any one

 

i think its okay now, i programmed a different ecu in a its been fine since so hopefully it should be ok now.

 

DID U BUY A NEW ONE AND HOW DID YOU PROGRAM IT
