Thread: Fuel pump circuit power draw car dies in 4 days

Disconnect That DAMN Capacitor. Bud and see what happens.

If you want to look for the issue. here's the fp wiring

The capacitor doesn't affect the draw whether its in the car or not. I just used a basic power tester in the fusebox under the hood, the kind with the lightbulb in the handle. I pulled the fuses out one by one to diagnose what circuit it was The stereo circuit the light is lit but not very bright. FuelP circuit that **** lights like a xmas tree. Does anyone know how to wire a kill swtich that isnt wired through the ignition? Rather from the battery to prevent power loss.

Thanks again for the wiring pictures, I will still try to find the problem.

A kill switch for the ignition or the fuel wiring?

Sure..I've seen some racing kill switches that interupt battery power. Check your parts stores and or summit/jegs.

I still dont forsee how you are figuring out the circuit draw with a simple test light. Grab yourself a cheap Digital Multi meter and Disconnect the positive terminal. Put the DMM in series with the battery and disconnected terminal. Then Set the Multimeter to the MA (Milliamp) Range.


Another pointer is Have the battery Tested.

Do what Brian said. The light test is just to test to see if there is power there. Not to rate how much power there is depending on how bright the damn light lights up....

And According to BillBoosts schematic The fuel pump fuse is HOT at all times. Pump is controlled by a Relay.

Ill get a Digital Multi meter to see how much is being drawn. The battery is brand new, the previous battery was swollen from freezing and it was toast. I'm only 19 and this is the only GM ive liked enough to buy, im a ford guy :P I am eager to make this car better than my 99 Eddie bauer 5.0l explorer.
