Car: 1986 Cutlass Engine: 305 Transmission: 200-4R | Zero spark? (cavalier)
Not a Camaro problem, it's my Cavalier. 1991 Z24 that uses a 730 ecm and DIS ignition system, you guys may be able to help with that part.
Started car, drove it into the garage, put air in the tire, went to start car again and the engine won't fire. Turns over fine. No sputter nothing, just like the ignition is off. Check for spark, I have none at any plug. Check for any trouble codes, ecm only flashes 12 as normal. Take out the coils and module, have the module tested and it's fine.
That's where I am at right now. I was banking on it being the module, similar symptoms to the 2 HEI module I have had gone bad on other cars. For the past month the car breaks up a little at 4000rpm, then is fine. Then one day no start. I also checked the crank sensor and the resistance was within spec.
Any ideas? Is there anything else computer related that would cause zero spark without setting a code or at least cause it to run in limp mode? I will grab another module and coil set from the wrecker, toss it in and see what happens.
Thank you for any help, I am out of town untill sat, so I apoplgize if I don't respond for a while.
