Ok so i bought a noid light. I have pressure at the rail, all the injectors are firing, i have spark, my timing is correct and has been confirmed several times. I am CONVINCED that this is a mechanical problem. Either timing chain or valve train.

When i hold my foot to the floor it will give me pops through the intake and sometimes a backfire out the exhaust. It backfires so loud from the exhaust my neighbor actually came over to see what was going on.

ok if you jumped timing it could do all that stuff. verify that TDC and distributor agree. being a mechanic also even though a ford (will forgive you) I'll take it the distributor is very close to reinstalled fairly close to the clock position it came out at.
reestablish your TDC and see

this is going to sound a bit odd take a medium sized screwdriver and give the mass air flow sensor (black sensor between air cleaner a throttle body)a bit of a smack not to hard, I have been told the maf is a bit like light bulb when the filament gets tired give it a tap

no need to unplug it but I am running out of things and I don't have the manual, and I am also starting to suspect the ECM, or 1 of other many things In the middle. but I would love to know what it is and I am going to ask some of my friends what they think.

Heres the rest of the compression readings. It took quite a few seconds of cranking before it stopped increasing. Sometimes i could only get about 120 psi but if i stopped for a moment and bumped it again it would jump to 130-135.

these numbers are fairly consistent,
much earlier it was established that the distributor was replaced with cap and so on, here is the question did you assemble the cap? under coil there is a stamped steel plate that sometimes needs to be removed from old and installed on new.

You have fuel pressure, you have a good spark,injectors are pulsing,timing is good, no way this car should't fire up... Damn do you put that dizzy the right way in? Sure is the base timing good? Wires ? Mismatched?once i was stranded by my 85,i had 12 v at dizzy but no spark it was the ignition module that was gone un 1k miles... Cheap quality dynaspark from Ecklers

go to a search browser, put in gm hei cap photos look at the pictures. There is a steel piece about 4" long it goes from the plug area on top and is secured under the coil. WITH OUT IT IM PRETTY SURE NO BOOM or at least a weak spark
