I have a 2004 Chevy Classic (Malibu). It will not turn over.

Customer Question

I have a 2004 Chevy Classic (Malibu). It will not turn over. Battery is new and upon last work, starter was good. If I try starting with the e-brake on or from nuetral, it will kick over but not hold. Will not kick over from park. Someone mentioned 'Transmission Selector'. Could this be right? What could it be? What may be a cheap fix?

Your friend is talking about the nuetral safety switch on the transmission which also works the back up lamps. It is possible for this switch to go bad or to be loose on it mountings, in which case it may not work in park and you may need to move the shift lever around while holding the key in the start position to make the starter work. I would rather you started your testing at the starter, just as a precaution. If you use a 12 volt test light or a volt meter and check the purple wire on the starter solenoid. If you turn the key to the crank position and you have voltage to both this wire and the battery terminal on the solenoid, then the starter is bad. If you do not have voltage to the small purple wire on the solenoid, then we need to check the nuetral safety switch on the top of the transmission where the shift cable is connected. You will be looking for either 2 purple wires, one from the ignition switch to the nuetral switch and one from the nuetral switch to the starter or the one coming into the nuetral switch from the ignition switch may be yellow instead. Let me know what you find and we will go from there. Picture of the nuetral switch below. Note, it does require a special tool to align the nuetral switch, Chevy dealer only, as far as I know. Thanks

Thank You for your time, sir. This will obviously (with the lack of specialty tools) be a task for a mechanic or dealer shop. We will try and use this information as best we can to address the problem ourselves, but realize this is a fix for the experts (such as yourself).

 

Thanks again,

Kevin and Melody.

Expert:  Bob replied 5 years ago.
You are most welcome. But, if you can, test the starter yourself before spending money some place else. It just may end up not being that switch. But, if you test it first, then you will know for sure what your up against before spending your money. Then if they tell you the same thing as your test shows, you know you are dealing with an honest shop. Really appreciate the accept, if you need anything else, just drop us a note.
Customer: replied 5 years ago.

We will find a way to do that. We'd rather do as much as possible.. well, as cheap as possible. But, we'll do what is necessary to get the car up and running. We'll see what's possible tomorrow.

 

I'll definately keep you in mind should we have anymore questions. Again, Thanks to you and JA.
