These engines actually use a switch in the air flow meter to run the pump. Make sure it is connected, none of the wires broken and that the boot and those big vacuum hoses are in place. There is also a voltage reducing or ballast resistor for the injectors. I have seen them go bad (rare). All the injectors are wired in parallel. If none work and the pump is running and you have spark, you need to check wiring or suspect a bad ECU.

1980 VW Vanagon Westy not getting fuel Photos of engine compartment here <http://www.zzyzx.org/1980_Vanagon_Kingman/index.htm> . Problem is engine starts fine if primed then quits once primer fuel is exhausted. It will not start without being primed. It seems the fuel injection system is not functioning properly. I've checked grounds and plugs for sure fit. Bentley outlines several tests which I've completed the following one failed. Bentley 1980-1983 pg. 24.6 suggests testing voltage supply at injector plug by quote 1. remove connector from injector. 2. connect test light on connector plug. 3. operate starter, test light must flicker. "If NO, refer to AFC Troubleshooting Guide (pg 7) catalog no. US 42-00-5955-1" This test failed to produce a flickering of test light. The fuel pump is delivering fuel to the ring. It seems the computer is not signaling to the injectors properly A google search of "US 42-00-5955-1" failed to yield useful results. Any ideas as to what component could have failed or where to find AFC Troubleshooting Guide (pg 7) catalog no. US 42-00-5955-1 Any guidance is appreciated Steve |
