Power Fc Problem ?

[4hirpm]

hey people

got a bit of an issue with my car at the moment its an r32 gtst with a s2 rb25 in it running a power fc and everytime i go to start the car it won't go.

when i switch the ignition on the fuel pump relay in the boot is clicking on and off flat out when its priming but dosent stop priming the pump it just keeps clicking madly and car won't fire up when cranked over strange thing is some times it fires up and run's fine the u turn it off and try to start it and it won't go

has replaced the relay still the same thing have started looking for a bad earth in the main loom thinking mayb the power fc is faulty sending bad signal or something any help would be great

who installed the FC

did it ever work

have you checked the wiring

have you checked all fuses and relays

check the fuel control system, the R33 has a different fuel control relay vs R32
