Quick question for anyone that can help.....I have a 2000 Silverado with the 5.3, when I go to start the truck sometimes (Intermittent) it take a good while to start (as long as 5 seconds). I recently changed the fuel pump becuase the fuel gauge was acting crazy and I was advised by another GM mechanic (Neighbor that moved) that there was a short and it was about to leave me stranded....and I definately do not want that.

I know that I have seen some topics suggesting a Fuel pressure regulator but is there a sensor that could be the cause of this too? Maybe and Idle or Throttle position sensor.

Any help from anyone is appreciated.

  Ha!! So GM Customer service, ive already been talking with someone on your email team and there is nothing they can do. So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
