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

First of all, the injectors won't spray when you move the flap. You have to touch the white wire from the point side of the coil to ground to get a pair of injectors to fire.

If it stalled as you were driving, odds are you've lost an electrical connection or a ground for the relay. Losing the CHT sensor connection will do it, too, or the CHT sensor being loose in the head. That's common on Bus engines where the CHT sensor is right out in the open. Or the Pertronix unit could have puked, something that's pretty common, IME. PM me with a GOOD e-mail address and I'll send you an L-jet guide. It's a big file, BTW.

Good luck! The Cap'n

I could get it to almost restart if I pumped the heck out of the gas pedal and cranked, it would fire and sputter for a second before dying again.
Would it still be electrical?
