2002 M35 Issues

[stagea-and-skylines]

Hi, i have a 2002 m35 stagea car broke down the other night and when called the raa they said fuel issues most prob fuel pump took to mechanic who ran some tests and thought same prob so swapped the fuel pump but car still doing the exact same thing will idle fine but for some reason when you give it throttle is does nothing besides try and die the mechanic said for some reason the pump is only getting 1/4 of the voltage it should be and the injectors are dumping three times as much fuel as they should be, he has no idea why has been troubleshooting for a week now, any one else with this issue and how they fixed it ?

post in the Stagea section for better help. but have them test/check the AFM as they are a common issue on the M35's. but again best bet post in the Stagea section for better answers of others with M35's that may have had this issue
