Ok 91 CRX B17a1 Rywire engien harness and obd-obd1 jumper harness.

Here's the problem Swapped Intake Manifold,Throttle Body over the weekend and 3 days later the car wouldn't start and i didn't hear the relay clicking or the fuel pump coming on, So i took my other car to work. Now i cam home after 6pm and tried starting the car and it started with alittle help from the gas pedel i heard the relay and fuel pump.That night i drove it and it started and ran fine. Next morning i jumped in and it didnt want to start again the engine turns over fine, but the relay and fuel didnt make a sound. I know main relay tried 1 new and 2 used ones same thing, now here is what i tried i jumped the fuel pump yel/blk wire with 12v and the fuel pump turn on and then the car started.Then i tried with just the key and nothing. I wiggle each wire one at a time and when i wiggled the BLK it the relay clicked.So fine the i figured if it did start just wiggle the wires. But i dont want to do that all the time so i am asking for some help if anyone has had this problem to chime in. I have put a whole pack of Dielectric grease in there and the car has been starting for a couple of days with out a problem until to day. I know a ground comes off the ecu and a couple of wires as well to the main relay but i dont know if one has to do with the other please is anyone has had this problem open to idea's.It's a stock ecu for the
B17 engine.Also i dont think swapping the intake and throttle body would cause this problem.
Thanks in advance Hope somebody can help

Wow over 60 view's and no one has anything to say...

 

your going to have to trace the wire back that would make it start when wiggled. and jus look for a loose or bad connection on that wire
