Fuel pump?

Asked by Apr 15, 2017 at 10:49 AM about the 2005 Chevrolet Classic

Question type: Maintenance & Repair

My daughter has a 05 Chevy Classic. A couple
months ago it died on her after sputtering for a
second, then after a couple tries it started up and
stayed running. We took it to the parts store and
had it put on the computer, it read either a purge
valve or purge sensor, both of which I believe to be
part of the fuel system. It has ran fine since then
until a couple days ago, it did the same thing
except it won't start at all now. The people I've
asked about it insist it's the fuel pump, I'm hoping
it's the much less expensive sensor or valve.
Opinions are welcomed and needed! Also my sister
has a 99 cutlass that she's about to scrap, would
that fuel pump be compatible? The cars are very
similar .

The '99 Cutlass fuel pump is not compatible. All you need to do with the fuel pump to know if it is good is to check the fuel pump pressure to see if it is in the specified range.

If the purge valve is stuck open you may be getting raw fuel to the engine through the EVAP system. In other words, it's flooded. Try holding the accelerator pedal to the floor while cranking. This puts the computer in "clear flood mode". You can turn the ignition on but don't try to start it. You should be able to hear the fuel pump run for about 3 to 5 seconds. HTH. -Jim
