No fuel

I am getting no fuel from the injectors. New fuel pump (working), new filter, injection control module is good, and I have spark. Fuses are good too. I checked the injectors and one of them is good, the other is bad. Would one bad injector cause there to be no fuel from the good one? I am thinking the fuel line from the filter up to the TBI unit could be clogged. When I removed the old pump it had a lot of gunk in it. Obviously I need to replace the injector that is bad, but that still will not solve the issue, or will it? I have even heard that the distributor is the cause of my issue. See pictures.

This picture is the underside of the top cover. I have no idea what it is supposed to look like, but I do not think it should look like this, lol.

Hello,

Where is the ignition module for the distributor I do not see it? Also, watch that small piece of gasket material left on the throttle body it will cause a leak.

Please let us know.

Cheers, Ken

I did not take a picture of it but the white dot was yellow. I tested it four times and each time it came back as good so I did not replace it. And yes I scrapped the old gasket and replaced with a new one.

If you have spark and fuel pressure lets check for injector pulse when the engine is cranking over.

Here is a guide:

Let me know if you get pulse.

Please let us know what happens.

Cheers, Ken

Injector pulse is fine. I finally dropped the tank again and the line from the sending unit was completely blocked. Blew it out, reconnected all fuel lines and got fuel up and out of the injectors.
