Was going to pick up my shiny new ACP hood and a set of brakes today but my car had other thoughts on the matter.

Here's how it went down.

The car has been parked for about 2 months now, and I have to admit the last drive it was driven hard and put away wet. So friday night, I took the battery out and charged it for the night. This morning the car started right up and I was ready to go...........however, while it was warming up the car stalled........ no check engine light, no sputtering, nothing, just dead (still tons of oil pressure though so that's a relief). After popping the hood and checking things out a little I turned the key and the car started right up once again. Thinking this was a one time occurence I didn't think anything more of it and headed off. This lasted for about 10 minutes until I was in midtown Manhattan when the car once again just died; no matter what I did she wouldn't even offer, I was even on a hill and tried to bump start it.

To wrap up my little story the car was towed home and is now in the driveway. I've checked the fuel filter and made sure the battery is fully charged, I've also drained the fuel that was sitting for the couple of months and put in fresh fuel. Now when I start the car it again starts right up will run for 30 seconds or so, and will then just die; once it does this I can crank all I want and it won't fire at all. However after letting the car sit for a little while it will again start right up.

Anyone have any thoughts on what the culprit may be????? I'm starting to think it may be a crank sensor.

Codes are below, I don't think any of them are related however.

A6-SCM

I'm pretty sure the majority of these are related to the battery being dead from sitting.

Thanks for reading and any help you have. Please forgive my lovely ppunctuation and grammar, I've been having a couple of beers to cope.

 

Since it consistently dies after running, I'd check the fuel pressure at the rail, and monitor it when the car is running to see if it drops off before it dies. Not uncommon for a pump to behave in this manner.

 

I have dual pumps on the car (stock and the ECS kit pump) so I'd be suprised if this was the problem, I'll check in the morning though.

 

Hey Matt,

Your codes are all "H" history. I would try resetting them and see if anything comes back. Most of them are in reference to the battery being disconnected.

 

Ya, I didn't think they were related.

 

Someone has to have had this before!

 

Need to reset codes and see if any new codes appear.

- Check battery cables since you recently removed.

- Have you tried jumping off of another car ? Don't remove cables and see if it runs. You could have a bad battery.

What was you alternator voltage ?

Since you're running a blower to you have a fuel pressure gauge and if so is it around 58 PSI ?

Have you checked your belts ?

 

If you are looking for a "one size fits all answer", it probably won't happen. You post a problem, and guys ask questions, and ask you to check certain things........like fuel pressure.

 

I know I know, I actually used to be a auto tech so I know that asking people to diagnose things without having the car in front of them is a real shot in the dark. I was just hoping that someone would have had the exact same problem and save me the research.

 

Sure, there are similar circumstances....for a stock car....which obviously yours is not...which can complicate things.

As an former auto tech, this should be a simple issue to isolate for you......fuel, air, spark, etc.

Good luck.

 

I'm betting on a chaffed wire somewhere.

 

Your vette is pissed at you for letting it sit
