My friend and I just finished swapping in a odd1 b16 in his 96 dx, when we first tried to start it we had no fuel so we traced it to the main relay. We have tested the ground and the 12 volt switched and constant, if we bypass the relay it runs fine but if we replace the relay the fuel pump doesn't turn on any ideas?

If it worked before,im sure its gonna work fine after. Main relays dont go bad because you swapped over a motor. Id look in another direction. Alarm system?

no alarm, he bought the car as a slightly abused shell

Got it. Then continue troubleshooting.


If you bypass Blu/wht to Yellow/grn then of course you will have a fuel pump turn on. I dont think its the Main relay. It may be an input from the PCM

thanks, we used the dx harness with a jumper obd2a - obd1 would that affect it?

did you plug the big green one thats around the ecu? that causes your car not to start and prime. the plug thats outside the ecu.
