'95 LT1

Car sat untouched for 2 months (in dry garage). Tried it today (after charging battery) and nothing. Dash lights light up and headlights are strong. Battery tested to 11.2 volts.

Got under the car and tested the starter connections...all good....well battery power good, signal wire from key dead of course.

Fuel pump doesn't prime.

After trying a while the PKE light came up on the console display (first time I've seen it light up). Cleaned the pellet and contacts repeatedly. Waited 10 - 15 mins. Still no joy.

Pulled the PKE fuse and light stayed on. Disconnected battery and reconnected and light went out.

Tried the wait thing again.....cleaned the pellet again and still nothing.

Tried to pull codes (PCM and PKE) but nothing came up on the dash display. Nothing. Not even C12.

Tried doing a search but couldn't find any more info than what I've listed above.

I TRIED doing the Service Manual thing.....but after 2 hours of reading I'm still lost.

Any help would be very much appreciated.

I would start with the battery. At 11.2 v, and if its been sitting, it's contacts may be bad... also, 11.2v isn't the key, it's current. If the battery doesn't have the amps, it won't fire.

Low voltage will also mess with the computers. So if there isn't enough to power them, oops... no love.

I would pull the battery, take it and have it tested. That's my best guess... or, best first stab.

I've had had bad grounds give me weird problems, including one like this...you never know what could have gotten corroded or come loose...

I hear you Andy. But 11.2v would be enough to engage the starter solenoid, if not the starter itself.
I put the trickle charge back on the battery and with it connected shows 12.84 volts and still no crank.

I'm thinking it's perhaps somewhere in the PKE system?

Oh, I know what you're saying Joseph! I had wierd things happen last year and re-did all my grounds in engine bay. Dielectric grease on all ground and battery contacts.

Just checked them and they're making good contact.

11.2 is more than enough to spin the starter. So is 10.5.


"Got under the car and tested the starter connections...all good....well battery power good, signal wire from key dead of course."

Did you have someone turn the key to "start" when you did this? If there's no volrage there, you have to find out if there's voltage at the starter enable relay (opwer comes thru either the clutch switch ot PARK switch.

Though I'm thinkin' that the problem is some where else since the fuel pump enable relay doesn't seem to be working either.

And like Joe said, the grounds need to be checked.

What exactly is happening on the dssh(with no codes coming up).
Is the dash lit up like normal with the key on?

I'll check the starter enable relay.

My thoughts also......of note: The "security" light doesn't come on, even for a second. Thinking I'm 'locked out' as in the key chip isn't being read?

And like Joe said, the grounds need to be checked.

Did that.

The idiot lights all work but the central display remains dead.

Check the 5 amp fuse marked LCD, it provides power to the dash display and also puts power into the CCM (there may be other power to the CCM also).

Edit - this fuse also provids power to the Security light.

PKE has nothing to do with starting. It is simply the thing that unlocks the doors.

Volts are one thing... but if the battery has a bad cell, that's another. And sitting dead for this long could have killed it. I reiterate, it hurts nothing to test it.

Stupid me.....meant to say VATS, not PKE!

I thought the VATS was deleted in my tune though.

Point taken about the battery Andy. I'm resistant to assuming it's a battery problem simply because it's only 8 months old (Costco). Since replacing it, it's been fine so long as I start it up every few weeks (never needed a charge). This time I was so busy I had to ignore the vette for 2 months......so I simply assumed it needed a trickle charge. After charging it up (2Amp) for a few days I tried to start it this morning.....with results as described above.

Tomorrow I'll trace the starter relay and let you all know.

AND I'll double check the grounds just to make certain.

Thanks all.

sounds like you need a battery tender...

Life intruded today. Never got the Start Relay tested. Bill, I did check the fuse to the LCD (it was good).

I did however have the opportunity to research my specific problem on line and I gotta say, there's very few people that have had my same symptoms.....no crank/dead security light & info centre.

I'm slowly concluding I have a bad ground somewhere.....so I'm going to carry on with that assumption and chase all the grounds down. (which I believe wouldn't be a waste of time regardless)

At the same time I'll be checking further on the + side of the circuits.

Truth is that there's been a whole bunch of aftermarket (read novice) alterations to the wiring under the dash before I got it 8 years ago and after removing most of it then, the cars been fine.

So what I'm saying is it may finally be my time to Pay the Piper!

Will keep you all in the loop.
Thank you all so much for your advice.

From my experience, running through the "no start" troubleshooting chart in the FSM is your best bet. I've used the various charts on several occasions and although some of the tests are a PIA they are always spot on. Don't just guess at stuff. I've done that (in my haste) and it makes the troubleshooting process twice as long.

Hi guys,

Well, I finally found the problem. It was my CCM.

After chasing down every ground I ended up calling Ken @ K&B, described the issues and he felt confident that it was the ccm. I sent it down to him and he got it repaired and back to me quickly (Thanks Ken).

I got very busy with work so didn't have the time to get it back into the vette until this morning (hellish job)....but got it all buttoned up by noon and voila'. Been driving it around all afternoon, before the rain begins tomorrow.

Thanks for all the advice and helping me to think it all through.

Awesome!
