i have been diagnosing a hard start on my 1994 yukon
today i checked the fuel pressure pump will prime to 13psi then immediately drop to zero it is not holding pressure at all....running its 13psi but i cant test it under load
warm starts are easy one crank cold starts its chugga chugga chugga till it decides it wants to start
is this the pump or is there another part that will hold pressure to start
