Hi. Having problems with my 300zx tt not starting after a full engine rebuild, auto to manual conversion, high flowed turbos, bigger injectors, wiring specialties engine harness, dw300 fuel pump etc. Engine cranks over no problems but won't fire, good voltage in coil pack connectors, fuel pump fuse and relay but there is no voltage going to the fuel pump connection or FPCM, it also seems as there is no voltage going to the ecu after checking pin 16 where the harness plugs in to the ecu with a multimeter. It seems strange as other parts of the wiring harness such as the coil pack connectors and the abs control module are getting perfect battery voltage, also the fuel pump relay but where the plugs connect with the fuel pump it is completly dead. Im not sure if the car alarm is somehow stopping the fuel pump and ecu from working as some sort of immobilizer function. I would greatly appreciate any help as the car is basically finished and this is driving me nutts, Thanks.
