74 1.8 L-Jet No Run - Help Please!, No fuel out of injectors Options

[SteveL]

74 1.8 with L-Jet
- Gas in tank
- Key on and AFM flap moved with screwdriver, I can hear the pump run.
- Removed fuel injector and placed in jar. Key on, moved AFM flap (can hear pump running), no fuel. Reconnected AFM to air intake and cranked it over (can't hear pump over starter), still no fuel in jar. Propped the AFM flap open, key on (can hear pump running), cranked it over, still no fuel in jar.

Best I can figure, I think it must be one of the following:
- plugged fuel filter?
- fuel pump spinning, but not actually pumping fuel?
- fuel pressure regulator?
- injectors not receiving signal to spray?

Any suggestions?

Thanks

do you have a 'noid' light to check for signal to the injectors? pump running, signal to injectors, no fuel…try filter (easiest). have you ever cleaned or inspected the tank or replaced the output tube screen/sock? is this a out of the blue development or a sometimes it does and sometimes it doesn't?

This is the first time it has failed to start. However, this summer when I go to start it I had to crank for a few seconds for the fuel to get there before it would start, rather than firing instantly. I seems like the fuel was back-draining when shut off.
