I have no voltage on the fuel pump relay any idea what might be causing this?

Did You Check The Fuse?

Did You Wack The Bumpers Real Hard?
Sometimes In An Accident, The Pump Is Shut
Off For Safety. Your Owners Book Should Point
Out A Reset Button.

Fuel Pump Relay Up On The Firewall Could Be Bad.
Or Power Going To It.

Get Out A Book And A Good Voltmeter.

Good Luck!

I dont know if this is the same problem or not but I had a problem that I thought was the fuel pump. I could start the truck unless if I poured some gas down in the throttle body but it would alwas die after running for few seconds. I replaced the fuel pump which is in the gas tank! A real pain in the butt.
Still had the same problem. I finally took it to the Chevy dealer and they for 180.00 replaced the ingnition module and said that it the sparc part of it was fine but it had a circut in it that told the throttle body injectors to tell the fuel pump to charge them with gas. I know it sound weird but It has worked great ever since.

Hope this helps,
Chris.

Have someone take something and hit your gas tank a few times while you try to start it. You may think it sounds crazy but it is a trick that I've used and seen work if you fuel pump won't kick on.
