Hey guys I need help with my gas gauge. It worked before the swap but I think it runs on the same circuit as the ecm, I took those fuses out along with the computer. Correct me if I'm wrong but isn't the fuel gauge connected with the pump? I already ran out of gas with this beast trying to get things back in order. Thanks for any input

Alright would it be easier to hook up a after market gas gauge?

The '94-'01 model years did not use the PCM for the fuel gauge.
The instrument cluster will need to be powered 12+ for the fuel gauge to work.
The fuel pump and the fuel level sensor have a common ground at the tank. Make sure this ground is good.

It's a 87 s15 pick up

So you have three wires, Hot for the pump, ground for the ground and the third wire is the fuel level.
It should run to the gauge and the gauge should have a hot wire.

On those older S10s the gauges all grounded on a screw at the bottom left side of the dash. The gauges would go all wacky if the screw got a little loose.

Yeah that's exactly what it does. It acts like its working sometimes but not sure if its reading fuel level or just a wacky ground. Going to fiddle with it and see thanks everyone.
