[Vwdiesel] More Quantum questions?-progress

[William J Toensing]

Finally get the Quantum's engine all back together. Then tried to start it. No luck, not even a pop. Cracked the fuel line to #1 cylinder, no fuel. Dido the return line from the #4 injector return line to the IP. However the clear plastic line from the fuel filter to the IP looks like it is full, no bubbles. I suspect the fuel on/off solenoid at the rear of the IP might not be functioning. Would appreciating suggestions for trouble shooting it & other possibilities. Before I took the head off, the car did run.
