I have a 1996 K2500,5.7,136,000 miles, automatic. It had been running great, but quit on the way home a couple nights ago, just like turning off the key. I have spark but no fuel. I can't hear the pump come on when I turn the key. When I put a jumper wire from the 87 to 30 terminals on the relay, I get 11+ volts at the connector where it plugs into the pump harness, but nothing from the pump. I just replaced the pump less than 2 years ago, but it sure seems to be the pump; although I had a lot of symptoms before the last one failed. Any thoughts? One thing that sort of puzzled me: I plugged the relay in but left it sticking up enough to touch the 30 and 87 prongs on the relay with my meter probe. I had 11+ on the 87 but 0 on the 30, with the key on, like it wasn't getting power through the relay. Could a bad relay be the problem? Thanks.
