00 corvette electrical issues! HELP!
New to the forums been searching multiple forums all day need help with my 2000 corvette. Just bought it last weekend. My issue is this.
Starts out with:
Check/low tire pressure
Service Tcs
Reduced engine power
Fuel guage is reading empty
Coolant guage is buried
Security lights on
Abs lights on
Oil pressure gauge wasn't working I replaced that.
Dash is freaking out.
15 min later start up car again can drive it 10+ miles on the freeway with no issues. Car doesn't seem to have reduced power when everything is whacked out. Car runs and drives great. Almost seems like when I turn the tcs off is when I start to throw all these lights. Battery and alternator were both tested with a GR8. Any input would be really helpful!
On a side note the passenger side door had no power to lock,window, or mirrors. I looked at the wires running through the door seemed ok everyting started working again.

I have pulled the codes with the engine off. There's a bunch of "H" codes. I saw that other thread earlier and all of the guages and reduced power would be caused by a bad ground somewhere in the door?

Thanks guys. I read the other thread and realized the connectors were not in the door. I'll try and fish them out and see what's going on. Had no engine lights or any issues going to work today.

Pull your codes and record them (actual codes) and then delete them since you know what you had.
Drive your car and then pull your codes at some point again BEFORE you turn the ignition OFF. Most all codes will show as H once you turn the car OOF and some related to the EBCM will not even show.
Always record what codes show up under each module heading, it makes a difference especially in No Communication (Serial Bus) ones.
