Truck shuts off

Asked by Bobgreen1977 Jan 19, 2018 at 02:43 PM about the 2000 GMC Sierra 1500 SL 4WD Extended Cab LB

Question type: Maintenance & Repair

My truck starts and shuts off like it is out of fuel.
But there is 18 gallons of gas in it. Changed the
fuel regulater and still does it. I can't hear fuel
pump. And wanted to know if it might b something
other than fuel pump.

could be the sending unit , which is on the pump , make sure the pump has a good ground and power at the disconnect , check fuel pressure some vehicles are particular and just having it won't do , check for spark when it dies
