[QUOTE="Philngruvy, post: 56860, member: 632"] Bobbie-g, thanks for the reply. I have good fuel flow to the pump. Plenty of flow at the solenoid fuel shut off and yes the solenoid is good and working properly. I have blown out the injector supply lines. I have squeezed that doggone primer bulb until my arthritic fingers are aching, both with the engine turning over and with it not turning over.
