I have a '75 1.8L L-Jet that has sat for a while. Its my parts car, but I'm trying to get it running now.
When I got it, the fellow told me the double relay was bad, so I replaced that. Fuel lines were also totally gummed at the tank, so those have been changed, tank cleaned and fuel filter replaced. I also had the fuel injectors tested and cleanded. I had also found a shredded "stray" wire, which turned out to be the engine temp sensor (under the engine sheet metal), which was replaced. The car will "fire" when I spray starting fluid in the intake. I don't have a pressure guage, but the pressure is sufficient to blow an improperly clamped fuel line off the fuel rail (I had an injector out, and some fuel must've sprayed into the hole, causing a "sputtering" near-start). I pulled the injectors to see if they were spraying, and they are not. When I manipulate the AFM flap, I can hear both the fuel pump as well as a "hissing" sound from the pressure regulator (but can not see any leaks). Troubleshooting these type issues is not my strength (IMG:style_emoticons/default/confused24.gif) so any help/advice on where I need to look next would be greatly appreciated. |

Remove the distributor. Hook an ground wire from the distributor to the engine. Spin the distributor with the key on. The injectors should click. If you can't hear them, put a automotive stethoscope on each injector.
Another alternative is to get a noid light and test the injector leads. (IMG:http://www.914world.com/bbs2/uploads_offsite/ww2.justanswer.com-1143-1346710982.1.jpg) It is plugged in to the injector leads. If the light flickers, your injector circuit is fine. They are available at your FLAPS. |

When you say ground the distributor, is there a particular place that this needs to hook to, or just connect a wire to the distributor body and then engine? |
