Hi,
Hope someone on here can help with some promlems I\'ve been having.
Car is an \'89 EGI (G Plate), 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.
 
Many thanks

Prof

Not sure on the EGI, but for a Turbo II, the fuel pump resistor relay is behind the drivers side headlight (inside the bulkhead) on a metal bracket.  There is also a main relay - that\'s up near the charcoal canister on the firewall - passenger side.
 
The EGI\'s had the flapper type air flow meter - there is a safety cutout switch in it that will turn off the fuel pump if the car tips over - so if the AFM has been moved altered - it may be worth looking at that.

Thanks man, any help finding the right wiring diagram for that and the fuel pump relay in the FSM?
