1998 Chevy Suburban V8 Four Wheel Drive Automatic 115000 miles
Engine will not start due to lack of fuel pressure.
Fuel pump works when the relay contacts are closed manually for trouble shooting. Fuel Pressure then rises to normal.
It looks like the power from the ECM is not turning on the relay. The voltage from the ECM is not present. The relay works and all fuses are fine.
Could it be the ECM.
Has anyone had to replace the main ECM before in order to solve the fuel pump relay controle problem?
have the same problem?
