More info on wierd problem
Still won't start, but more info. Injectors are good, fuel pump works, good fuel pressure, tach bounces, starter turns fast. I got it running tonight after a lot of messing around with the idle screw and the little hex thing in the AFM. It wouldn't idle, and when i hit the gas it would stay idling very high and not come back down. I even changed out the AFM with a spare no change. After snooping around i saw the intake manifold bolts were literally falling out. If i hadn't caught it, im certain 2 of them would have fallen out. So i tightened them to 15 ft/lbs, now i cant get it to run at all. I have spark, fuel, compression, no idea where to go from here, especially since i had it running about 5 times today for a substantial amount of time BEFORE i tightened the bolts. After i tightened the manifold down, I did play around with idle screw and AFM screw again with no luck.

You have messed up the AFM settings on both units. You will have to go back if you remember how many turns you made on each one. Use the link below to help you straighten out the mess. Air Flow Sensor (AFM) Never mess with the AFM unless you read up on it first. You have to remember how many turns you made on the idle screw.

Thank the good Lord for that. When ever I make adjustment I have to write it down as I do it. I suffer from CRS so bad any more, the older I get the worse it gets.
