I have a starting problem with my 1986 Firebird. It stalled the other day while going down the road (wasn't even on the clutch), and now it won't start.

On this car, the previous owner created a wiring nightmare. In short, the cooling fans wouldn't turn on, so he wired a toggle switch to turn them on when needed. The lock cylinder and key won't start the car when turned to "start," so he hotwired a push-button system straight to the starter, and now you have to turn the car to "on" and hit the button to start the car. After this "fix," if you turn the lock cylinder/key to the "start" position, the brake light comes on and the temperature gauge goes all the way up (obviously, not the car's actual temperature, just the gauge reading).

So...the symptoms:
--The headlights won't flip up, but they do turn on as I can see the lights shining under the bumper.
--No lights (dash, interior, etc.) come on with the lock cylinder/key in the "on" position.
--Power windows won't roll back up
--The fuel pump doesn't click on with the lock cylinder/key in the "on" position, but DOES turn on when the car is cranked (with the button hotwired to the starter, the car still cranks but won't fully start).

What I've done so far:
Checked battery. It is working properly.
Got a new ignition switch. Pain in the {chain of expletives} to un-/re-install, so I took off all the wires and connections from the uninstalled switch and fully hooked up the new switch, minus actually securing it to the steering column. By moving the rod attached to between the lock cylinder and the switch, I went through all of the switch positions....and still nothing.


I am at a total loss as to what could be the cause of the problem. Only other thing I could think of would be the PCM, but before I replace that I would like to know if ANYONE has had the same problem and knows of something else to do to make it work again. Just anything...I'm at a loss. Any help would be appreciated.

Thanks!

I'm having the same prob with my 94 as we speek I trying to fig it out my self
 
do you have power going to the ECM, that is under the hood. all of this happening because of the wire that were either cut or bypassed. the fuel pump should turn on with ignition in the on position not the start position. everthing is banking on the egnition switch wiring harness. head lights have relays and thet are constantly powered regardless of the key position. same with fog lights. you have a mess if he cut splice wires just to rig the switch up to get it running. good luck , it would take me week to staighten out a mess like that.

Got it figured out. There were two fusible links connected to the starter that were corroded and broke. They weren't on any wiring diagrams that I could find...but it fixed the problem. Car starts now, but the alternator died somewhere along the line. Just one problem after another :rolleyes:
