Let's start from the beginning. Did you have the fuel pump replaced because the engine light was on? If so, do you know what fault code was stored in the computer at that time. Also, and more important, what code is currently causing the light to come on . There are a lot of different faults which will all set different fault codes and turn the engine light on. If you can tell me what codes is current now I can try and tell you what may be wrong.

Yep, same problem. When that check engine light is on it I can't use my electric start, plus it does the "might/might not" start thing. UNRELIABLE at best.

My check engine light would stay on for 2 months go off for a day or two and then back on turned out to be the thermostat - about 250.00 to replace
