VR 1994 UTE 5sp

[datsun 70]

Hi guy's i am pretty much at wits end, it will not start, originally it turned over with original key but through EXTENSIVE recearch i found that the BCM was corroded beyond repair. so i have replaced it with a compatable unit , my mechanic mate said all is good BUT now i do not have any ignition lights so no power is getting to the computer. my question is why don't i have any ignition when i had it before? How do i get this car to run. any advise is welcome

Did you change the BCM while the battery was still conected? you may have blown a fuse somewhere.

Hi guy,s yes i had a blown fuse but looked intact i should have known. And yes i have it running the problem was that the fuel relay was not sending a proper volatge to the pump so i bridged the terminals with the relay out and it started then i replaced the relay and so it goes. Thanks
