Give me some direction, bringing car back from the dead
Ok so we have an 86 n/a that we are trying to get to fire up. The car sat for a few years before we got it. I have searched to a pretty good extent.
New battery, is getting spark, and has excellent compression. I believe it is not getting fuel. When the test connector is jumped, I can hear fuel going through the fuel rail. When I pull the plugs and crank it, I cannot see any puffs of gas coming out.
What are some things to start checking?

If it sat for a couple of years, it wouldn't hurt to inject a few teaspoons of Marvel Mystery Oil in each rotor. Some people use ATF but Marvel Mystery Oil will do the same thing and it lubricates better. You will probably have to add it moire than once.
The way I do it, I inject a little in each bank, turn the motor over a little , then put the plugs back in and see if it will fire.

That's the first thing I did to the engine, even before I put it on the trailer.
Compression isn't the issue here. I haven't done a standard test, but when cranking, I get 3 even puffs of air on each rotor, very strong. I know it's just an estimate, but I'm very confident in the compression of this engine.
I definitely am sure it's fuel related now. After a half an hour of tinkering and cranking, there was not a drop of gas on the plugs. Usually, (on my car) if I pull the plugs and crank it, I get puffs of fuel vapor comin out. With this car I get nada.
I plan on pulling the intake and swapping the primary injectors and fuel rails with known good spares sometime soon, but keep the input coming. I'm also going to swap out the MAF for the sake of doing it.
