Hi,



Been pointed over to this forum by another Rotary enthusiast friend of mine.

Car is an '89 EGI, I have recently done the rats nest and air pump / emmissions removal stuff and (predictably) the car is now not starting. The engine will turn over and spark but not fire as the fuel pump is not priming / pumping fuel.



Somewhere in the car's history it has been owned by some complete pirates, the wiring has been seriously bodged, it had 2 ecus in the pass footwell (one faulty) and none of the wiring colours or relay positions from the FSM seem to match. I've got a fluctuating 12v signal at the fuel pump when the ign is turned on but nothing before that and the pump is not priming.



Please could someone point me in the right direction of where the fuel pump relay should be located / looks like and if posible (and even better), what the circuit diagram should look like for this system. From looking at the FSM's and various other guides on the net, it isn't clear where the fault on my system is as nothing on my car matches up.



Many thanks

 

Fuel pump resistor relay is usually bolted to the engine bay side of the core support behind the passenger headlight, a large heatsink obscures it from plain view as well as the stock air box if youre still running it.
