Ok here goes i have 1996 chevy camaro z28 with the lt1. I bought the car about a month ago not running, i had to replace a bad optispark and while I was working on it i replaced the plugs,wires,fuel filter, crank position sensor, and pcv valve. The car ran like champ up intill sunday. I was pulling out and it just died for a split second seemed like ignition cut out. It kicked back in and i drove about 1 mile or so and the car shut off completly. I pulled over and started the car back up it idled but when i reved it up it cut out and shut down. I was only a few miles from home so i drove it home and kept it at a very low rpm. When i got home i reved it again and it cut out but didn't shut down. I did get a code and i called autozone and they told me it was a bad ignition coil. I forgot to write the code down sorry. So anyway i put the new coil on and then it didn't start. That was sunday. I got up on monday and went out to the car and it fired up i drove it 500ft to my garage and let it idle it idled for 2min or so and shut down. So i went and got a new ignition control modual and tried that no luck so i put the old one back on and returned the new one. I am starting to think that the optispark is not sending the info to the pcm is there any way to check to see what the optispark is sending the pcm? ohm or any voltage you can check? So what i have is a brand new coil, 1month old optispark,plugs,wires but car will not run? any input or ideas would be greatly appricated!

Thanks Travis motoman626@gmail.com

 

i have a same problem... i got a 97 camaro ss... lt1 and i just got a complete engine overall done including everything in the engine like bearings, pistons, piston rings, oilpump, timing chain everything... and i got exactly the same prob... i donno wat to do.. my mech tells me to get a computer checkup done.. must b some sensor.... throttle position sensor... or the speed sensor or the maf sensor.. not sure exactly... hopefully some1 else must have had the same problem and mayb they can help us out.. the rpm goes High when neutral and when the car goes on D the rpm is normal tats 900 or something.. n then when it shifts to P or N... its almost 1400.. even after heating the car up for 30 mins or so... waiting for some ideas or the solution... thanks in advance

 

hey i guess the problem is with the sensor that fits to the water pump.. so i got mine replaced and the car is working completely fine now.. but there is still some prob with the rpm.. so need to check that today.. but the car is not turning off and its ok now.. so u shud check urs aswell..

 

well i thank you all for the support, i think it got it fixed i replaced the coil ($35.00), icm ($75.00) and the connector ($48.00) that plugs into the coil. So it all looks good for now i'll let you all know if anything changes! Thanks Again Travis

 

no go, it let me sit again sunday night It did give me two codes this time a po372 and a p1371 so from what i can tell the opti isn't working correctly after only a little over 1,000 miles? Don't buy them from autozone seems like they problems! I'm going to get the msd 83811 and hope that fixes my problems thanks again everyone
