Mk 3 Fuel Pump wiring issue
Hi All,
Have an issue with fuel pump not firing with key on. As per the manual and wiring diagrams I've checked all fuses, fuel pump relay, Circuit opening relay (removed and tested on +12V, cleaned contacts, triggers as it should). The pump itself seems fine, when I short the Fp and B+ terminals on the diagnosis link it fires and delivers fuel to the fuel rail. What it won't do is fire up and deliver fuel when cranking or with key to IGN. Without pulling the entire interior to inspect wiring, any thoughts? ECU? Something I haven't checked? Any genuine leads much appreciated, need this car running!!! Cheers |
