1G Advice needed with no start condition

[drich970]

Just got my build put together. 1g 6bolt. This has been an ongoing build for the last 5 years. Everything from valve cover to oil pan done.

My issue:

Car turns over great, but not starting. I got it to start for about a half a second. I have narrowed it down to fuel. I have good spark and compression. I have good fuel pressure at the rail. But after pulling the plugs I have no fuel on them and no smell of fuel except in one cylinder. I pulled of the CAS and rotated it by hand and can feel the injectors pulsing but still no fuel in the cylinder. This is how I also checked for spark. Pulling the plug and turning the CAS which showed spark on every cylinder.

My question is do you guys think it's possible for every fuel injector to be plugged? Also is there a way to test the injectors without pulling them from the head. Maybe pulling a plug and look in the cylinder while cranking, which I did and didn't see fuel.

The injectors are old 660's so that's why I'm leaning towards them as the culprit.

Thought I would reach out and ask for advice.

Thankyou everyone.

Sounds like you’re on the right track. You could build a DIY injector tester/cleaner if you want to. If you’re not familiar with Jafro, he has a couple of videos on YT about building and using the one he made. Here’s a link to the first one.

Appreciate the reply. I'll look into this.

Agree that the injectors are the likely cause...especially if the injectors sat for a long time with fuel in them. The fuel would have evaporated causing a buildup of varnish on the needle.
