Need help starting a 75 1.8L L-Jet in NoVA, Injectors not spraying Options

[wrightee]

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.

Pin 33 and 32 looks like injector 1 and 4. So if your getting voltage at the ECU connector at these pins, and you apply ground to these pins, you'll be able to fire them. I understand the inability to hear this in a noisy environment. You can remove injector 1 and 4 from the intake, and visually look for spray mist.

After the Coke dip for each injector connector, spray them down with ether or something, to remove the residue.

Correction, I may have read the schematic wrong. What you stated earlier about the injectors for what cylinders that corresponds with pin 33 and 32 maybe correct.

I'm going off a good diagram I found on Jeff Bowlsby's site with a hand-drawn schematic of the L-Jet wiring.



Also, I found this unused (green) wire, but I was guessing it was from the condensor that was pulled out for the CompuFire ignition (IMG:style_emoticons/default/confused24.gif)
