I have a 94 Lumina APV With a 3.1 engine. I parked it and went to start it 1 hr. Later and it would not start. After checking it over I found it was not getting any gas. I thought it was the fuel pump so I replaced it, but still no fuel. I can make the pump run by applying 12 volts to the fuel pump test terminal. I have replaced fuel pump, ECM, oil pressure sensor, and ESC. I have checked the relay and it is fine. When I turn on the key the pump does not come on, but after you crank it for a while it will run for a second when you quit cranking. Also, I get no pulse signal to the TBI to make the fuel spray. I can make it spray manually by jumpering it out, I have the steady 12 volts. And when you hook up a scanner it says there is no communication with the computer.
have the same problem?
