mechanic says fuel pump bad

Chev equinox 2008

While on vacation, the fuel gauge began to stay on zero. Tried filling, but the tank was full. Went to a close GM service location and was told the it was probably a module of some sort and should be no problem driving.

Car ran fine, no problems starting or running. Drove home 3rd day 500 miles. Drove around home town 3 days waiting for an appointment with the local GM dealer.

This company has had the car 2 days and called today saying it was a bad fuel pump. I am not a mechanic, but sounds strange. Just wondered if I was being overly paronoid? Is this a case of faulty diagnosis? Thanks

Tvaughn,

I am sorry to hear that you are experiencing issues with your Equinox. Please let me know if the issue is still occurring once you get your vehicle back from the dealership.

Thank you,

Elizabeth, Chevrolet Customer Service

If the vehicle runs & drives fine the primary fuel pump is fine, but the secondary fuel pump could be bad.

One of the fuel level sensors could be bad too causing the gauge to give a false reading.

Yes, the Equinox does in fact have two fuel modules and each has it's own fuel level sensor. The two modules are necessary due to the "saddle" design of the fuel tank which splits the tank into two portions or "reservoirs". The primary module is on the right side of the tank and contains a primary and secondary fuel pump. The primary fuel pump supplies the engine with fuel; the secondary pump pumps fuel to the "primary" (right) side of the tank via a cross tube. The secondary module is on the left and does not have a fuel pump in it. The fuel level sensors are available as a separate part on the Equinox unlike most other older GM models where it was only sold with the entire fuel pump/module assembly.

There is no access panel so the fuel tank does need to be removed to replace them.
