injector question I have a 98 TA with an LS1 that has developed a serious problem. One morning it just would not start. After having a new pump put in the car due to no fuel pressure, It STILL has no fuel pressure. Me and a friend started doing some checking, and when you hotwire the pump at the relay, it builds pressure, so the pump is in and working properly. The injectors on the car are NOT clicking, so it seems the PCM is not sending the proper pulse to open them.
What would cause the car to have no pressure unless hotwired, and have no injector pulses? Possibly a bad PCM?
Thanks for your help.
