2004 pontiac grand am: ocassionally..the fuel pump..cranking

Resolved Question:

I have a 2004 pontiac grand am. I am having problems with it starting ocassionally. I know it has to do with the fuel pump, because I can't here the pump come on when the key is turned on, but usually it will eventually start, after I re-charge the battery, due to too much cranking. A couple of days ago it completely shut off while driving. I know the fuel pump is coming on because I can't hear it when the key is turned on. I have heard of resetting the computer but these techniques do not work. Any advice will be great!

The resetting procedure is only for problems relating to the security system. If this was a security related problem, you would still hear the fuel pump run, the engine would start for a second or two and the engine would cut off. Your problem is with the fuel pump itself. It is common for a fuel pump to act up before failing completely. You will need to replace your fuel pump.

That is what I was afraid of. Is that something I can do myself? I have worked on cars my whole life so do you think it can be done at home?
Expert:  Dave Nova replied 4 years ago.

It can be done at home. The fuel tank must be removed from the vehicle to replace the pump. Hopefully your tank isn't completely full when you try to remove it.
