I have a 92 chevy Z71 full size pickup. Has 350 and the truck will not start, no fuel at the throttlebody. I can hear the fuel pump run when I turn the key over for a couple seconds. When its primed it just runs until the fuel burns then dies again. Thanks for any help..

clogged fuel filter, blown injector fuse.

fuel pump relay is good. injector fuse..where is the injector fuse on this truck with a throttlebody?? Thanks

maxxman04

relay good, but how is the filter? fuse is in fuse panel, should be marked "INJ" if i remember right.

Hogfan

filter is good, removed it and had gas run out of both lines going to tank and to engine..and gas looked very good.

Hogfan

ok, i was listening again when i turn the key over today and i hear the relay click under the hood and here a click at the tank but no buzzing sound for a couple seconds....think I have a bad fuel pump after all

Rent a Fuel pressure gauge and test it at the fuel rail. Your truck will not shoot fuel through the TBI if you dont have spark so check that first.

Hogfan

when its primed with gas it will run for a few seconds, so would that not tell me that I have spark??

maxxman04

yes, there is spark. does sound like pump is shot. not hard to replace. make sure you get a new wiring kit when you buy pump. parts stores should have these in stock. the old wires tend to burn/melt just a little. splice new wires in place of old, good to go.

thanks, I will get the wiring kit
