im not getting power to my fuel pump, i have replaced the relay, checked fuses and still no power, but when i run direct power to my (ALDL) on terminal G in it turns on, so whats next??

 

I believe the fuse is up near the battery on my IROC, might be there on yours as well.

 

Yea i just check it....

 

Is the relay working? If not, you'll need to check wiring back to the ECM...if okay, I'd suspect ECM is not firing the relay.

Do a search, you'll find the schematics posted, verify you have power to the coils of the relay when the key is on...this will only last for about 2 seconds...so either pu the meter where it's viewable, or have a friend turn the key.

 

well...i got it going, the wire harness on the relay was bad thanx for the help!

 

Cool...and welcome to thirdgen.org

 

Glad you got it fixed, Gabe! I had a similar problem; the ring terminal for the fuel pump fuse, at the positive junction block, on the passenger side of the radiator support, was the cause of my headache. The wire corroded and became intermittant.
