hey guys i have a 93 rx7 with a ls1 swap in it. last night i parked my car and it shut off just fine. came out this morning to find my car was completely dead. put it on a quick charge and turned it over. then when i went to turn the car off i pulled the key out and the car was still on. i could put the key back in and turn it and i could take it back out as many times as i wanted but it wouldnt turn the car off. i was looking around and i saw some stuff about a locked cylinder? does anyone know whats wrong with mine or know how i can fix it?
thanks

Derek

 

Locked ignitions are a common problem among most GM models.

I know you have an ls1 but I'm sure the stock ignition doesn't get touched. Even though it's a swapped car.

 

Why not go to the V8 forum?

 

could be an alternator wiring issue or issue within the alternator itself. if the signal wire off the ignition switch shorts out within the alternator it will cross flow and keep the engine alive even with the key off as well as drain the battery to nothing with the engine off.

 

Rotary guys can't get their cars to start, LS1 guys can't get the car to stop running.

 

That made me crack up. Bravo!

 

I agree. If it isn't this than something electrical is malfunctioning, mis-connected, shorted, etc.

Start troubleshooting the electrical. If RotaryEvolution is right, disconnect the alternator and the car should run / stop correctly ... assuming that your battery is charged up.

Hmm ... could also disconnect the lock cylinder while the car is running to see if it's stuck on. If the car continues to run when you pull the lock cylinder than the cylinder is more than likely OK.

You might also consider (with the car off) charging the battery, pulling a fuse, putting a tester across the open fuse contacts, replacing the fuse and then moving on. You're looking for the circuit that makes the tester light up. This is the circuit that is shorted on. I would check all of them, one by one.

Hope that this gives you some places to start. Let us know what you find.

 

crazy late response im sorry but this was hilarious again sorry its been so long i totally forgot about my post because of school and everything. but it turns out the previous owner had installed a kill switch and something went bad in the wiring so i just ripped it out and re wired everything back the way it was supposed to be. as of now so far so good =D thanks for those who commented much appreciated

did you ever figure what the problem was?

 

Bump, as i'm curious as well. I may be having ignition switch issues in my 93 as well.

 

FWIW, 99% of the issues like this I've seen on swapped cars are wiring issues, and I've worked on a lot of these swaps.
