Default 05 saturn Vue


I replaced my head on my saturn vue 2.2 ecotech. Car was sitting for about 1 year and now the fuel gauge shows empty and the fuel pump is not pumping gas. checked the fuses and they are good. what to check now?

Can you hear the fuel pump making any noise at all?

I THINK it's possible that the gas may have partially congealed (gelled up) as the gas went bad over the 1 yr (assuming no gas stabilizer added.

Possibly pinhole leak in tank and gas leaked out during the year?

Might consider pulling the fuel filter for a looksy. If it is clogged this may be part or alll of the problem

Did you check fuel pressure at the rail under the hood?

Default Hello

My Tank is full. Ran a jumper wire from the fuse box to the gray wire for the fuel pump and its working relay is good because I tested it. fuel getting to the fuel rail with the jumper wire. but disconecting the jumper wire the fuel pump stops.
I Might have a short in the fuse box under the hood?

Does the car run with the jumper wires hooked up?
I'd say it is likely a bad electrical connection where the relay plugs in--corrosion form sitting outside and inactive for so long. The relay itself may be fine but if there is not good conductivity on the 5V (12V?) signal connections OR the ones passing the higher load currents, then it behaves as an incomplete electrical circuit
