Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi, my name is ***** ***** I will assist you. What do you mean by "stays engaged", are you saying that the starter continues to spin?
It seems to me that you have a faulty transmission range sensor. All of your symptoms fit it. The transmission range sensor (sometimes also incorrectly referred to as the neutral safety switch) is responsible, among other things, for allowing power to be sent to the starter only when the transmission is in the park or neutral gear. In order to do this, there is a power circuit always present inside the sensor, so if the sensor shorts internally it can not only prevent the vehicle from starting, but can force the stater to turn even after the engine starts and is running.
It is possible that it could also cause the battery not to charge, but this could also be another issue. We can go through some tests on it...do you have a multimeter available and are you able to use it?
Ok, so the first thing to check would be the purple wire coming out of the switch. This is the control circuit for the starter and it will be energized anytime the signal is being sent to the starter. If the starter is engaging while the engine is running, you should check this here. If it is getting power, then you can assume that it is getting a signal from the switch. If you have cut power from the switch, then you have already proven this to a point.
*p.s. the yellow wire that feeds power to the range switch also provides power to other accessories, including the alternator. This is why you are no longer getting power from the alternator.
Have you had any luck checking the items I mentioned?
Not a problem, and of course no rush
Hi, this is Josh checking in on your progress. Have you decided to replace the range switch? Do you have any further questions? If so, please let me know. Otherwise, if you are satisfied with my answer, please take a moment to leave a positive rating using the star rating system above. Thanks!
I suppose it is possible; what do you mean he fried the cables?
Oh, wow. I can't say that I've seen that particular instance happen before but I guess it is conceivable that the starter could have overheated as a result of your problem and subsequently heated up the cable directly to the battery. I don't think that this is likely, however.
Hello and welcome!
Different expert here.
Did you still need help?
If so, please let me know. I will be happy to help!
You will need to remove any aftermarket components such as the push button remote start and hook the starting circuit back up the way it came from the factory.
If it sparked at the battery, that means there is a bad connection.
I think it would be best if we could speak on the phone.
How about if I lower the price for the additional service from $26 to $5 bucks?
Ok, not a problem. We can continue then.
Have a great night!
Where you you checking for voltage? At the battery or at the starter?
Is the battery fully charged?
Ok, then the connections at the battery are bad or the battery itself is bad and will need to be replaced.
If you have a short in the system sir, the fuse would blow. Thats why they are there.
Because there is continunity. Thats how it works.
The problem is a bad battery. I guarantee it

Ok, please upload a picture or a video so I can see.
"the same results"
Ok, no problem. Dont switch them. Just send me a picture or a video of the current results.
Post them on youtube and then post the link to the video on this page.
It says "This video is unavailable."
Try sending it to my cell phone. You should see the number in my additional service.
Thank you for the video. However, it does not show any voltage readings??
YUP! That is low voltage!
YES, get the voltage back up to where it needs to be.
No sir, that is not normal.
YES, I believe I can get one for you. Please rate my answer for assisting you with all of your questions and I will send it right over.
Thank you for the positive rating.
One minute while I get a diagram for you.
If your sure there is no voltage on the big wire going to the back of the alternator, then I would be willing to bet that the alternator was not charging causing the battery to drain.. and now the low voltage condition.
This wire going to the back of the alternator gets power from a fusible link at the starter.. which gets power from the battery. Click on the link below to view the wiring diagram of this circuit.
Right, most likley because the fusible link is blown.
Or the wire from the starter to the alternator is bad.
Again it is at the starter.
You can also see this in the wiring diagram I have provided.
Ok, then thats most likley the problem.
YES, let me get you a wiring diagram of the starter motor.
So now the alternator will be able to charge once you get the engine up and running again.
Try jumping the vehicle with jumper cables from another vehicle.
NO, the alternator would not cause the starter to go bad.
If you do in fact have a good engine ground and are getting full battery voltage to the starter when jumping power to it, either the starter is bad or the engine is locked up.
So the starter is bad..
