mass air flow sensor codes......just replaced the
mafs for the second time and plugs/cap/rotor.

Maybe a plugged up catalytic converter. A muffler shop can do a back pressure test.

I installed a fuel pump on my 2002 GMC Sonome engine 4 cyl. It started righd not startet up. But, after driven 2 miles, stalled out and died. Since then I could start only after taking out pump out of tank and reinstalled. Oil pressure is more than 40 PSI. I can not find any voltage from terminal.. I put a hotwire (jumper) from 87 terminal to 30 Terminal in fuel pump relay terminal, still no juice. I put a wire from batter to straight to pump . The new pump made noise . Still could not start. In this morning I put a jumper from 87 terminal to pump. I managed the engine running. I could start without jumper about 5 times. While the engine running, I decided to take my truck to road test. Whiel the engine running, I was gathering some tools and equipment for in case of broke down, the engine shut off. Why does my truck do this? I need help, please. 3 Answers
