Mitch and I been working on this 5.2L with M112. We are trying to the engine fire up but still after changing the fuel pump still no fuel in the return line. What of the some of the cause of this? There is fuel in the inlet line but no return.
Possible Cause:
1. Physical Obstruction of fuel rails
2. Fuel Regulator
3. Fuel Pressure not enough
4. Fuel filter
5. Fuel pump control?
