Oky, so i wired it all up and replaced the starter (blew one up :) ) and now it turns over but NO fuel.
no sound from the fuel pump, shouldn't it make a noise when u put the key in position 2?
relay clicks in the fuse box but nothing else fuel wise.

swappped the fuel in/out pipes round and no difference.

checked the wiring and the fuel pump wire is connected correctly.

help?? i want the beast running tomorrow!!

wont be moving tho since the rear axel is still disconnected.

If the relay is clicking ok then it sounds like the pump itself, yes it should make a noise to pressurize the fuel rail. Have you pulled the relay and jumpered the pins with a pice of wire to eliminate the relay as the problem?

Take the pump out and beat it with a hammer, then see if it works:) They can stick from time to time.

na, its gotta be to do with the wiring. i just linked the m50 to the e30 so thats gotta be it. i linked the correct wires for the pump tho so not sure, it could be to do with the three relays on the engine loom as i dont know which colour goes in which plug.

just check the pump with a multimeter make sure your getting power to it , to check the pump dissconnect the lines and cross the pins behind the relay

Got the baby working...

Spoke to jayson from chipped uk, he sent me the correct ECU and it works fine, started straight away even tho its been sitting for ages.

Sounds like a monster truck tho with no manifolds
