truck starts but stalls out after a few seconds. both tanks have gas, and fuel presure at fuel rail is at 45 psi. when key is in the run possision. but as soon as you turn the motor over it drops to below 10 psi. it also drops to zero when you turn the key back to the off possission. anotherwords , it isnt holding presure....?????
