1996 chevy camaro z 28 v6 wont start sometimes it starts but then after a couple days nothing the alt is ok but the battery will not keep a charge. I also cant hear the fuel pump humming. Does anyone else know if i should change the fuel pump? confused
The Alt is okay but the battery won't keep a charge? Replace the battery. At least take it to an auto parts store, and have them do a load test.
Your fuel pump is electric. When you turn the key on it pumps up. After it has developed the needed pressure, it no longer pumps, hence you won't hear it working anymore.
Diagnose your problem going through the various systems. Right now you have a problem with the starting system. It sounds like, from your explanation, that the battery is bad.
If your battery checks out, and then you have the alternator checked out, you have an electrical drain. This may be tough to find.
After you replace your battery, wait 10 minutes, then try to start your Camaro. If it doesn't start, (Key to the Off position), take the Positive battery cable loose. Wait 2 minutes, then reconnect it. You are resetting the computer.
