Cranks, sparks, no fuel, no mmmmmm

Ok. I've got an 88 N/a that had been sitting for awhile. I figured I try to get it going. It won't fire so I propped open the AFM and got it to run. Once it was running I took my prop out and everything was fine ran good and strong.
Turned it off came back acouple days later and I had to go through the same process to get it going but it took a little more cranking to get it going.

Tried acouple days later and it wouldn't start for nothing. I tried ether, I tried everything i could think of, nothing. So I took off the UIM Cleaned out the injectors with cleaner put them back, bought a need gasket, and triied to start it. Nothing.

Now through all this sometimes I would have fuel pressure sometimes not. So I figured The filter or something was clogged and was going to replace it later. BUT Even if the filter is clogged shouldn't the ether still get it to fire? All it does is crank over. It's got spark it smokes out of the exhaust. Maybe it's flooded. I took the plugs out and spun it alot. Still no mmmmmmmmm.

Any ideas? bad AFM, bad computer?
