Bad fuel pump

Will a bad fuel pump through the red lighting bolt on the 04 hemi???

I don't think a bad fuel pump will give you any lights. I believe that lightning bolt tells you there is something wrong with the electronic throttle control system. Some guys here have added an extra ground wire to the throttle body and seen improved response and better idling. Don't know if that's your problem but it might be worth a try.

Yes red lightning bolt is issue with electronic throttle control.

Have you recently unplugged your throttle body? Make sure that it is plugged back in all the way and see if that fixes the problem
