What year is it?

On the mark 6 2002-2009 shape EAC fault can mean lots of didfeeent things it’s not a very specific fault, could be anything between the throttle pedal and the ecu.


You need to get the fault code read, clear them all out and start it again then read the codes again.

Cheapest thing to change is the pedal.

Last time I had this fault on a Fiesta tried lots of things nothing worked until we sent the Ecu off to ecu testing to get repaired for £220 plus vat and that fixed it.




Cheapest thing first is check the connector at the throttle pedal and try it.

2005 thanks for advice when running revs tics over perfect then when it cuts out imoberliser symbol stays on strange never had a problem with it in 4 years also when you put key in it doesn’t turn imoberliser of you have to play about with it

Suspect bad key/keys or sensor ring around the barrel

Scanned it today says code p0500a speed sensor bit confused as imoberliser was constantly flashing and eac fail came up on dash would this affect them any ideas thanks Dave

Doubt speedo fault codes have anything to do with the immobiliser

The fact that playing in the area of the barrel got it started does point to keys or sensor

Then again, if you got it running it shouldn't have cut out, built in safety and all that, thing is don't know the car well enough, sorry can't be of more help

No worries thanks anyway
