I have a 1994 GMC Jimmy with a 4.3L Vortex V-6 (CMFI). It has 120,000 miles. First thing I did when it would not start was replaced the Electric Fuel Pump and Strainer because I was not getting any fuel at the manifold fuel inlet line, also I did not hear the electric motor running inside the fuel tank like it used to. Went to start it right after I put fuel into the tank and it wouldn't start. I do have plenty of fuel now at the manifold inlet line, and I do hear the electric pump running. Went ahead and checked all the spark plug wires and ignition coil for sparks and I have plenty of fire. There is no check engine light codes given when I scanned it. Put a little fuel in the throttle body and it starts up real rough and only starts momentarily. Any suggestions would be greatly appreciated.
have the same problem?
