How do you know if your alternator is bad ??

General Motors vehicles do not have fuel pump reset switches.You have to check fuel pressure or fuses to find out if you have a problem with the fuel pump.Hope this helps.Good luck.

If you need to clear the codes after changing something where the check engine light had been on you will need to get with someone or a shop that has the right diagnostic tool to reset it. Unhooking the battery won't do it.

when you pushed caliper piston back dirty fluid traveled through the abs system causing valve to stick ,try bleeding the front brakes and resetting the computer.
