It's no biggie to me, but some times hijacking can be a real irritation.

next time just start a new thread but copy the URL of the thread you want to reference and include that in your post.

But I'm past the relay issue so if you need further help and if others don't mind replying you can reply back here since you've asked

Both those relays are the same, just connected to different things. So if you want to see if the relay is causing your issue, unplug them both and swap them (just making sure you keep track so you don't accidentally plug them into the same connector again).

If you're A/C doesn't work though, then there could be a SLIGHT possibility that both relays could be bad but I'd say that would be rare. But they are less than $10 at Advance Auto Parts. Just unplug one and take it with you.

But try swapping them first.

you can bypass the relay, if you're not sure about the condition of it, by simply running a jumper wire from pin 30 to 87 (the layout is marked on the relay itself). if the pump turns on, then the relay is bad.
but, before you drop the tank for a suspected bad pump check the fuse for it. i dropped the tank on my 'Burb, that was full (40 gals.), only to find a bad fuse after it still wouldn't start with the new pump.

The re;ay on the left is definately the fuel pump relay. According to my book, if it's a Vortec, the one on the right is the Intake Manifold Tuning Valve relay. Leaving this open probaly isn't a good idea especially with all the dirt and stuff I see around them. A new one will run you aboit $10 - $15 and will take about 5 minutes (if that) to change.

did you even read the thread Gimpy?

don't just read the OP, then offer up your diagnosis/opinion. read through the whole thread, then point it out if it's been missed. his relay issue was resolved on October 1st, plus this thread has laid dormant for over a month now.
