sierra with 50psi on fuel pump
2006 sierra 5.3...Having a issue starting....it will start for about a second and stall...tested the pump today with one cycle of the key and gave me 50 psi...i didnt cycle it much but held its pressure after a min...its been sitting for a few months...what else should i check for? 50 psi should be enough to start it right?
