I work at an auto body shop and about 2 months ago a 1990 TBI RS Camaro came in for a lot of body work (it was a high school kids car prior to the current owner and the prior owner fed it up) for the first month and half it ran great whenever we had to move it (which was 2 or 3 times a day on average). Then we let it set for 2 or 3 days and it wouldn’t start. So we replaced the coil and it still wouldn’t start then we replaced the dist module cap rotor spark plugs and wires and it still won’t start. The battery is new as well.
There is a dash light that caught my eye it is light up and I believe if I remember correctly it says "INFL RESET"
If anybody has any idea what this light is or any thoughts as to why the car has no spark and won’t start please let me know
The light you're seeing, the red "INFL REST" light, is the inflatable restraint light, also known as the airbag. When you turn the key on to accessories, or start the car, it should flash between 7-9 times, and then stop. If it does not stop flashing, than something is wrong in the SIR system.
Just to clarify, I'm assuming that the engine is cranking over, but is not catching and starting, correct? And there is no spark. Is fuel coming out of the injectors when you're cranking it? Make sure that your getting fuel into the engine, too. I would personally double-check everything under the hood. Check all the fuses (don't forget the one next to the battery on the passenger side inner fender area), check all the fusible links near the starter, make sure all the electrical connectors are tight (especially on the coil, I've had that problem), check the voltage on the battery, should be around 12.6V, check for disconnect vacuum lines, etc., etc. It's always the stupid little things that get to you.
My first thought was a bad ignition control module, but you've already replaced that. But, did you happen to test the pick-up coil while you had the cap, rotor, and ICM off of the distributor?
Huh so that’s what that light is the dealerships didn’t even know that. I guess ill have to whip out the snap-on computer and reset the airbags.
The engine cranks but wont start there is fuel getting to the engine I tested for power going to the coil and there is none; so I guess I’m going to be checking fuses and fusible links when I have time.
I see you said you replaced the dizzy module?, do you mean the ingniton control module? That thing crapped out on my car and gave all the same symtoms you speak of. $30 from autozone, and I was back on the road...

Bruce (90RS305)
i do beleave it was the ingniton control module
because i dont know what a dizzy module is.
lol, I'm sorry, you said a distributor (dizzy) module, thats what I was talking about. It's the little U shaped harness that 2 wires plug into (one leading to the coil)
He was referring to the ignition control module, which is what I am pretty sure you've replaced (the "dizzy module", as it was called earlier).
The pick-up coil is also located inside the distributor, but it cannot be replaced without taking the distributor out of the engine. It's round and has a 2-wire connector on it.
Here's what an ignition control module looks like:
Check the fuseable links next to the battery. I had some work done at a shop once and they blew the fuseable links. It wouldn't start, no click, nothing.
ok it cranks but it won`t start,have you tried checking the fuel injectors?fuel filter?to me without being there to hear what it sounds like it sounds to me to be fuel related.when you turn the key over to the on position do you hear the fuel pump kick on?if not check your fuses or the fuel relay.i`m not trying to steer you in the wrong direction just tring to point out a few other things not mentioned yet.
well i pulled the dist. today and was going to fix it when i found that part of its internals were cracked so i got a new one and i have spark
i made a small mistake that i didnt have time to fix today.
i accidently installed the dist 180degrees off so it wouldnt start but i will pull it back out and switch it around and it will work then i hope.
