so the holidays are all over and i finally have some time to work on my lt1 (impala ss) engine conversion. The lt1 is currently living inside a 1984 jaguar xj6. Everything is pretty much done, except my fuel pump has decided to give me a strange problem.
the car was running for a couple weeks -- however, the original fuel pump died. i assumed (correctly) that it was the bad gas in the tanks that caused the problem.
anyways i put in a new pump, after draining the bad gas, and tried again. it worked for a bit, then died. I realized there was no power getting to the pump. I probed the gray wire which feeds my fuel pump wire, and noticed it was not getting voltage. The gray wire which comes from the LT1 harness. I checked the fuses, and they all looked fine. I can hear a relay "click" when i turn the key to hot pos 2 (which makes the dash lights come on, etc), but no fuel pump engagement.
my question is: where should i start to tackle this problem? It must certainly be with my LT1 harness, correct? Is there a way to test if the relays are good?
any help would be much appreciated!
