Hi,
i have a crazy fuel pump ecu problem. if i turn the ignition on, the fpecu gets no signal from the ecu. if i start the car it runs 2 seconds and then it comes off. with 12v fuel pump mod, the engine runs.
i checked all relays, all fuses - all fine.
tested a other fpecu - same problem.
tested a other mainecu - same problem.
rewired the fpc and di wires directly from the mainecu to fpecu - same problem.
errorcodes ? - nothing.
i cant find the problem. have anybody a idea? my last option is the 12v mod but i want to find this failure :/
regards from germany
