with no problem. Fuel Pump or Modul? I had the floater device in gas tank & alternator replaced 2 months ago. 121K miles good condition. Check gas cap light & service engine light comes on. Car stalled while driving downtown. Gentleman stopped to help me & he tapped the gas tank & the car restarted & then cut off again. He said it could be the fuel pump or fuel pump module. Does this sound familiar? Can this cause the check gas cap & service engine lights to come on? Is this expensive?
 
when it dies again, remove gas tank cap anp place it back. If it starts replace the gas tank cap.
