Anti-theft or ignition switch I would guess. Do you have an alarm on this vehicle or the stock VATS type stuff?

horton72

It only has stock anti theft.just a red blinking light on the dash.I'm hoping that the new started I put in will be the solution

horton72

Now I think I have a bigger problem than the starter..all my dash lights,radio,gauges, headlights, blinkers,traction control and stability control turn on and off while I'm driving down the road but I can turn them back on by turning the key like I'm trying to start it

horton72

In order for my blinkers to work I have to turn the key over.forgot to mention also headlights turn off real quick then turn back on while I'm driving

Is your battery connections clean, kinda sounds like a dirty ground problem somewhere in system. Years ago a friend had a 81 trans am did same similar with taillights. every time it rained his lights wouldn't work. ended up being grounds.

horton72

Thanks man I'll give it a try and see what happens

horton72

no it didn't work I cleaned the battery post still didn't want to start unless I jump it off the starter then when it was started the lights flickered and all the gauges didn't work

horton72

I can make the dash lights and gauges work if I turn the key as if I'm starting the car

I would check and make sure your grounds are good as well then look into the BCM(body control module). Do a search for "Camaro bcm" and you'll find plenty. Not so uncommon an issue on aging F-body cars. Starting and most of the lights and such run through this. It would be helpful information to see of you can get a response from the PCM with a scan tool when the key is in but the dash lights won't work.

I guess we should have started with basics..what kind of vehicle is this?

2007 grand Prix gxp.80,000 miles

I am not familiar with that car.

So is it starting now or no? Are the "while driving" symptoms occurring now or previously when the car would start and drive?

horton72

It only starts by jumping it from starter to solenoid and everything goes haywire in park or driving.it has a 5.3 liter

horton72

When this all started it was only the car not starting then two days later is when everything else started

When driving, do the speedo and tach work? Other gauges?

horton72

All gauges don't work unless I turn the key over like I'm starting it

Sounds like it could be a problem with the ignition tumbler. GM tumblers are known to develop problems especially when owners hang a bunch of heavy stuff on their key rings.

Thank you all for the input but just an update..it was the ecm.I put my original ecm back in and everything went back to normal.now just waiting for my new programmed ecm to arrive in the mail

Curious here. Was the other ECM defective, or was it the wrong type?
