hey scotty, this past weekend i got home from work one day and had to pull my car out of the driveway after it had been off for 5 minutes. no problems before this moment at all but it would turn over and sputter a bit but it would not start. after further inspection i could not hear my fuel pump and my relays were good so i went and banged on the gas tank a couple times to see if i could free up the pump and ive been driving around ever since without any problems. should i be worried? the previous owner of this car had an invoice from the shop from 200 miles ago for this exact same problem but they could not figure out what was wrong because the car had started working again. where should i maybe start?
