m50 swap suddenly no power at pump

[mo diesil]

so my swap has been running for about 3+ years now and about a month ago i went to back out of my drive way and it wouldnt start.
its a 87 with the 2 pump setup, the pumps where not turning on and i had no tools at my house to check electrical, so i towed it down to my work, put in a 90 e30 pump and so on, car would not start checked electrical and no power only ground to the pump,
really need help on this one guys its getting tiring driving a stripped down turbo race car EVERYDAY... not exactly comfort,
any thoughts?

so u got to trace backwards then, see if you have power at the relay for the pump and then check continuity between the relay socket the fuel pump for power etc

Check for power at the relay.

im still at work and have yet to actually do anything, BUT FOR what is worth last night the relay was turning on

[singh336]

check continuity between the relay and pump maybe its broken somewhere between

Crank position sensor needs to see the crank spin before the ecu will ground out the fuel pump relay. If your crank position sensor is bad, you'll get what you describe.
