fuel pump rewire problem won't start

[johnk]

I re-wired my fuel pump useing the faq on plymouthlaser.com It's almost exactly the same as the one on VFAQ.com except the wires from 86 and 85 are reversed.

The way I have mine setup is as follows
87 - black and white wire fuel pump side
87a - nothing, but gets power when ignition is off
86 - black and white wire from harness
85 - ground
30 - new power line straight from battery with fuse not blown

I've checked with a volt meter I get power on the new line. When I hit the pump test on my datalogger I also can hear/feel the relay clicking over so the power inside should be switching.

When I connect the black and white wire ends together the car will start like it use to but I want to use the larger power wire I just spend time and money putting in. Does anyone see any wires I reversed or something or if the whole setup looks good please let me know either way this whole project has had me confused a little.

I cant remember what the relay polls 85 and 86 do... but why did you switch them like you said?

Those re the grounds so it doesn't matter which way you hook them up, I would be willing to bet that you hooked up the wrong 87 pole, try using the other one and see if it works.

Problem Solved! I knew I just needed a few minutes away from the problem to see what was really wrong. I had the whole thing wired up right. The problem was the harness for my relay came broken. The wire for 87 was put into the crimp with out being stripped back so none of the wires were touching it. DAMN Radio Shack
