My 1994 C4 LT1 sometimes just won't start after it's been running, Operating temp 200-220 degrees. sometimes it's just died driving down the road. But I leave it just sit for a bit, hour maybe a few it starts right up. By the way when it starts, it STARTS RIGHT UP!!! I Don't have to turn it over, and over to get it to fire up!! I have done all the basic stuff to try to find the problem. I have fuel at the fuel rail. but I don't have spark at the spark plug? Have replaced the optispark,ignition control module, and have bypassed the Vat's also. Did that first... LOL Now someone sad that it the battery votes was below 12.4 that could cause the car to start and run, But that the ECM would read the low voltage and turn off the car??? What... Someone also said that it could b e the temp control module? Telling the ECM that the car was over heating and do the same? Others have told me that the ECM is bad and replace it. I don't think so??
Anybody??? I hope someone has the answer. Because I'm sick of having my car towed home all the time and having my friends and other car show guys talking about my white C4 like it's a lemon when I can't get it started.
