I've tested the fuel pressure at the fuel rail, not sure what pressures i should be reading.
ignition switch on fuel pump runs for about one second pressure reads 20 lbs, recycle the the ignition sw then it reads 40 lbs. with engine running I'm getting 31 lbs pressure on gauge. otherwise trucks runs just fine.
