Hey Gang.....went to start the VR C6 and it would not turn over...took the battery to the local auto parts store to have it tested thought it might have had a bad cell but it checked out as a good battery. Starter or alternator is the question....anyone know if in fact it's one of those two and what am I looking at cost wise......thx Ross

 

New alternators are about $350, rebuilts are about 1/2 that.

No clue on a starter.

 

How olds the battery??

 

Instead of throwing money at it have you checked the cable that goes from the battery to the starter solenoid at the solenoid connection (located on the starter). These are notorious for burning the connection resulting in a no start condition or many other electrical issues.

 

Im think it's the original battery...im the 2nd owner and have not replaced it

 

Thx for the tip Bob....I will check that

 

Year C6 ?? I think your DIC would let you know if the ALT wasn't doing it's job. corvettes are very fussy with voltage at start up. As said check the POS. cable at the starter, but if the battery has any issues, try a new one.

 

Sure sounds like the battery. What kind of test did they do? A load test is the only way to know if it's good or not.

 

If the car is more than a few years old, this seems to be a common occurrence and the first thing I'd check after battery load test.

 

I have an '06....I put a battery tender on it and it was never an issue
b4 this....they did a load test on the battery and told me it was good?

 

The load testers at a parts store aren't too reliable.
Easy to tell if it's the starter or battery. Jump start it or use a known good battery as a substitute. If it starts you know it's the battery (or charging system).

 

If it's the original 2006 battery, time for a new one as the first step; then go from there.

 

Hey guys....still need help here....put in a new starter today and it still wont fire up? Took the battery from my 2011 Malibu in it and it still wont fire? Starter must be getn power cause the solenoid is clicking? The cable seems ok and its covered in heat tape should I still pull it and replace? Any thoughts or help is appreciated...thx Ross

 

Check the power connection on the back of the fuse block. Although when I've seen that connection loose the power usually dies completely intermittenly.

Also check all your grounds.

A multi-meter will help trace electrical issues.

 

Bud,,,,,,,,,,,, Theres a lot more to cranking a C6 than just the battery and the starter.

If you POSITIVE that you have battery power to the starter solenoid, you need to examine the following:

- Do you have a security light on the IPC when you are trying to crank it?

- When you press the START button, does the IPC go blank (except for one light on the IPC) for approx 30-40 sec?

Here are the starting /cranking schematics that you need to troubleshoot:

 

Start with the last schematic on the bottom of the post above and check the fuse and relay!

You can have someone crank the engine and if you monitor the PURPLE /WHITE wire with a volt meter. You should have battery voltage on that wire when the START BUTTON is depressed.

Bill.....thx 4 all your help....Im not the greatest car mechanic that's for sure I usually (98% of the time) hire it done when it comes to cars so Im relying on my friends as my garage mechanics....with that said: When I push the ignition button the whole IPC goes blank with only the engine icon stays on I assume its the check engine symbol....as far as the security light im not sure which light that is.....like I posted earlier I took the battery from my 2011 Malibu and put it in the C6 and it still did not fire up so I assume the battery in the C6 is ok at least for now?
He did open the fuse box up and checked the starter relay fuse and it did not appear to be bad? I tryd to fire it up just a few mins ago and now it just seems dead no clicking from the starter today which was replaced yesterday......thx Ross

Well,,, first the bad news. Having been there before, I pretty sure that you have a bad BCM. My 06 Coupe had the same issues and after all the troubleshooting, the BCM needed to be replaced. Unfortunately that a dealer task because it requires reprogramming with the GM TECH2 with CANdi module.

On mine, if I disconnected the battery and reconnected it, it would start.

Bill

 

Damn.....oh well....hopefully I can push start the thing to get it to the shop. I really appreciate all your help with this Bill I will let you know what they come up with here in the near future...thx again Ross

 

To verivy this theory before you go thru the cost of another BCM,, measure the PURPLE/WHITE wire while someone presses the start button. If it has no voltage, the problem is at the CRANK RELAY.. Follow the voltage.
