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? (IMG:style_emoticons/default/WTF.gif) Any suggestions? Thanks |

I'm not an L-jet expert or guru but ...
I would check the double relay to see if the Fuel Injection control module is getting power, thing the fuel pump is a separate circuit in the double relay. I would also check to see if the Fuel Injection control module is getting the signal from the ignition points (white wire to the coil) since the FI won't try to operate the injectors unless it see the ignition signal.
