I have a 1991 Z28 350 24k miles it quit runing. I have fire to the plugs no pulse to the injectors. All injectors were replaced months prior of this problem. I replaced the Distributer all of it. No change, I replaced the ECM again no change. Car will crank over, but no pulse. Before the ECM was replaced the car would start and run for about 3 minutes, then die and would not start back up. So I repalced the ECM and now it just cranks. Some one told me it was the VATS system but not sure how a car would drive at 70 MPH then die and not run again. Not sure if the VATS does anything after the car is running. This was the intial problem. I could have two issues just not sure. Any advice would be appreciated. Thanks Steve

Car is running fine now. two injectors were reading low ohms 3-3.5. The should read between 17 and 16. If one injector is bad the ECM shuts all of them down.
