1996 S10 Fuel pump issues
1996 S10 4.3 4wd automatic.Fuel pump doesn't seem to be getting power. No whine when key is first turned on. Relay, if I'm checking the correct one, has 12 volts when key is in on position.
The relays in the glove compartment. However one diagram indicates the relay closest to the driver as the fuel pump relay, but a second diagram points to the middle one.

As long as the relays have the same numbers on them you can swap them around to see if that makes any differences. Also check the fuses. The fuel pump might be getting power but not making a whining sound because it is bad.

They have the same numbers and I have swapped them around. The fuel pump is new. I can make the pump run by using a couple of wires to the battery. So now I'm a little lost, okay a whole lot lost.

did you check the pump fuse ? I have a 99 blazer and the fuse is under the hood on the drivers side inside a black box ! check it and if it won't start it might be the fuel regulator on the fuel rail !

Fuel Pump Update.
I found the problem. It turns out that the oil pressure switch failed. After replacing it the fuel pump ran.
I have gotten the truck to run.
Thank you for your suggestions.
