    At pump relay, do you have gray, red, orange, black& white, and dark green & white wires in that plug, or can you not see them?

    Before even bothering with a diagram, take the fuse block out and check the wiring connections on the back side of the fuse holders.

Can you follow orange wire back to ECM, & there may be a fusible link in that wire.

It sounds like the fuel pump relay is bad. it should be located in the under hood fuse panel

    it sounds to me like your security feature has been activated. sounds like the computer has shut off the fuel pump.

I dont have power to my fuel pump. any idea? i have changed the pump, fuel filter, and checked all the fuses under the hood.


Have you checked the fuel pump relay? usually located near the fuse box.
All power leads installed correctly after pump replaced?

97 chevy 4.3 liter no spark no fuel pump running.


4.3 and 2.8 motors have a ceramic module in the distributor. if you have alot of miles on the truck, and there is no spark, that module is usually the culprit. easy to replace with a nut driver and some dielectric grease. mod is located in the distributor when you take the cap off look straight dowm and its right there.
also check eec relay and fuse. that will also cause the prob.
