Why does my fuel pump have to run several times before my truck won't start

Asked by Mar 07, 2017 at 04:04 PM about the 2003 Chevrolet Silverado 1500HD LT Crew Cab Short Bed 2WD

Question type: Maintenance & Repair

All of a sudden my truck  Will not start until I turn
my key on and off several times to allow the fuel
pump to run,  after allowing the fuel pump to prime
the system it starts automatically.  It does not
matter if it sits all day or if it sits for 10 min.  I have
160,000 miles on my truck I change the fuel filter
every year and use gas additives.  I have the 6.0
engine.

Fuel pump replacement soon.

Ordered a new A/C Delco fuel pump. Hope this fixes the problem.

After replacing my fuel pump my truck finally is back to normal!!! I ordered a ne A/C Delco fuel pump off Ebay for 115.00 dollars when the dealer wanted 450.00. Thanks for the help enginecreator!
