Default Lt1 no crank

94 z28 with a no crank issue. Car has always started up and ran fine. It sat for a couple weeks, so I started it up Thursday night and let it idle for awhile. Turned it off, unhooked battery, went home. Next morning I used the battery to start another car. Then put battery back into the camaro and now I'm getting nothing. No crank, no click, no nothing. Fuel pump primes, and all lights/accessories come on and work as they did before. Vats has already been bypassed. Only difference is that now when I turn the key on, my check engine light, and check gauges light come on. Low trac light also comes on and goes off when I turn the key to start, let off key and low trac light is back on. I've checked all fuses, and swapped out the starter/theft deterrent relay with a known good one, and the starter itself with a good one. Can't scan the car, nor can I check voltage at the purple wire at the moment. Any other ideas in the meantime?

Does not matter. What is the voltage? I've had more than one new battery go belly-up in short order.

Age =/= condition

plenty of new stuff is junk straight out of the box.

It shows correct voltage. I can take it out and put it in another car and it starts up right away like it should. I can also put another good battery in the camar and same problem persists. It's not a battery issue.

I began to check that. Didn't have time to get the switch off today and look at it, but I did unplug the pigtails, and they're not burnt. Will continue with that tomorrow.

Make sure your battery connections are clean and tight. I had a similar issue with my truck once, everything turned on like normal but nothing from starter. It was just a loose positive cable.

Cables and battery itself are clean, all grounds good also, but now that you mention it, I did use a different bolt for the positive cable when I put the battery back in Friday morning, and it had some rust on it. I'll have to check it out tomorrow.

x2. With your symptoms/explanation, it is probably a connection issue.

Did you check for voltage at the starter terminal?

that seems more likely than my previous assumption. More than likely you have enough contact to turn on some accessories but not Tp actually power anything that starts the vehicle.

No Moe, I didn't get to check voltage. Accidentally left my multimeter 350 miles away. You actually tuned the pcm for said car. I have another one I'll be sending you sometime soon. Anyway, I got called to work out of town late last night, so the issue will have to wait another week or two when I get back to be resolved. I'll post back here though when I get to try these other things. Thanks guys.

Update on this. Finally got back into town last night. It was as we suspected. Rust on positive battery terminal bolt. Swapped with another one, and started right up. Weird that everything else still worked previously minus the starter though! Never ran into a problem like that before
