Hello,
I would like to introduce myself as a newcomer to this forum. My name is Thomas, I'm from Dortmund, Germany and I drive a 2003 Esprit in Gunmetal. It's my 3rd Esprit and I love it.
Sorry for the bad english!
Can someone help me, I'm looking for an engine wiring diagram that includes the engine control unit and relays, suitable for Esprit V8
To the problem:
Turned off Esprit after a good lap...it should continue after a few days, but now it always goes off after about 5-10 seconds. Ramspott & Brandt from Wiesbaden gave me the tip to check both fuel pumps, then removed both pumps and one was actually damaged. So I replaced both pumps.
Now both pumps are running perfectly, pressure checked (4.2 bar), the car still switches off after 10 seconds, but I also have another problem now, as soon as I connect the battery pole, relay 22 (primary fuel pump & injectors) starts , so the pump runs continuously, even without the engine control unit, relay checked and replaced.....no improvement
So the relay must be controlled from somewhere, either by another relay or we have a cable problem. This can hardly be done without a wiring diagram.
Car starts perfectly, runs fine but always shuts off after the same amount of time and pump runs and runs.
greeting
Thomas
Pin 53 on the ECU was very interesting... checked everything. Two wires damaged... now it's working again 😀 Danke Gruß Thomas
