I have a 1990 T/A that im having some problems with. When I go to start it most of the time it does nothing (the check engine light and brake light come on and the temp gauge goes up) but the starter solenoid does not even click nor does it even attempt to turn over, Then at random after I try so many times it cranks right up. I am thinking about changing out the starter and solenoid but it seems like an ignition problem. Has anybody had this problem before??? Please help

Sounds like the starter solenoid to me, but it could also be the security system.

Security system? how would I go about checking if it was the security system? I recently installed an aftermarket CD playing in it, I spliced all the wires directly into the stock wiring harness, could that be a problem?

I believe you have the VATS system, and if so, there is a tech article in the tech article forum on how to disable VATS.

Holy cow... this is beginning to be an epidemic. If Bob's tech article doesn't work out for you, in one of my later posts in the gen specific (3rd gen) forum about a failing engine swap, there's a link to a VATS bypass module. Try the cheaper method of bypassing VATS with a resistor first.

Im going to go to the dealership today and get a new key made because my old one was slightly cracked which could be the problem, I am also going to get the resistance of the key incase i need to bypass VATS. if that doesnt work I'm prolly just gonna wire in a push button start.....

To work on the starter is actually quite simple.

1) Disconnect the negative battery terminal.
2) Jack up the passenger side.
3) Remove the cables to the starter, keeping in mind which cables go to which posts.
4) Remove the starter, it should be bolted to the engine with only two bolts, a long one and a short one.
5) You can resume your work on the starter with it removed from the engine not under the car, then reinstall the reverse of removal.

well I wound up using my friends lift to take off the starter so that made the job very simple. I however tested the starter with a battery charger (hooked up the ground to the starter case and the touched the positive to the switch terminal) and the starter turned over everytime, so my starter and solenoid are still good which means it must be my ignition switch. :gayfight:

However, a push button and about 10' of wire should fix my problem...

my 91 Formula did the same thing... i replaced the starter thinking that it could be the problem, and the car continued to do the same thing. then i changed the battery; turned out that i had a weak battery and that was what casued my starting problems. if you have a spare battery laying around or can get your hands on one i'd try that before i went through the trouble of wireing in a push button. :twocents:

Also you should check the KEY!!! My 90 Firebird would refuse to start. nothing happend. just got electrical turn on. Paid the 80 computer check and the mechanic came out and told me there was a slight bend, almost unseeable, and the special magnet chip thing key was not always hitting the tumblers right...thus not starting the engine cause of the security system... instead of paying the crazy price for a new key set....i used the spare.

Hey you know I have the same problem with my 97 v6 firebird. When you start the car does the security light come on and stay on after you turn the key off and take it out? If so just let it sit and when it goes off it should turn right over. The only problem with that is that you have to leave to go somewhere about five to ten minutes earlier to make sure you are not late. If you find out the cause of this let me know too because all I do now is just let it sit. Someone told me not to mess with the security system, meaning not to try bypassing because the car would not start, but if there is a way to bypass it I would sure like to know. Other then that try turning it on and if the security light stays on just let it sit and in a few minutes it will go off and then it should start right up. Now I have had it do it twice in a row to me once so just make sure to give yourself plenty of time to get somewhere if that is just the problem.
