2001 Dodge Ram only runs when gas is poured down throttle body. Changed crankshaft
position sensor, camshaft position sensor, coil and wires. Put in a rebuilt ECM. Checked
and found 50 psi at fuel rail. OBDII shows no codes. I am flat out of ideas, any hints.
Thanks

Check for injector pulse. Fuel pressure at the rail is great, but the injectors need to be pulsing to get the fuel into the cylinders.
