Hi guys
i went to start the car tonight and there is no power to fuel pump from relay.
Ive tried new relay no volts
Ive connected pump direct to battery ok.
Ive checked for feed behind ecu no volts.

I disconected the ecu and bridged out pins 1 + 10 and 19 +28 on ecu loom switched on ign and pump primes.

Reconnect ecu pump wont prime.

Disconted injectors and crank sensor, reconnected ecu pump now primes. Connect crank sensor and pump wont prime again

Has anyone got any ideas on what to do next

Cheers
Mark

if you can manually power the pump relay by grounding pin 28, then the wiring and relay all checks out ok.
You probably have a damaged ECU track, they normally burn the track up by the ecu plug.

As said above or crank sensor fault

Hi,
If you power the fuel pump directly does the engine run?
Cheers,

It sounds like the CPS, check the connector, sometimes a bad connection occurs here.
