Started, ran rough, now wont start

ok the car has been sitting for about 5 months or so with the front end jacked up on jack stands. I just finished my auto to manual conversion and had to buy a different starter. I put it in and started it, it started up, and was running really rough, I had to keep my foot on the gas to keep it running, then it died when I let go. I started it again, and I had to hold the gas even harder to keep it running (only at like 1000 RPM), and then I heard either 2 clunks or 2 backfires couldnt tell, so i let off and it died. Now it just turns over and doesnt start, or it gives one puff and a backfire/clunk (idk) every now and then. Anyone have any clue what the heck is wrong?? (ran fine when I started the project)

Just a quick guess...did you by chance forget to plug the MAS sensor clip back in?

Yeah I remembered to plug the MAS in. The guy at Autozone said that because it was sitting for so long the spark plugs may have been fouled, and because I kept trying to start it, fuel may have fouled the oil! But the oil is brand new, and I don't see how the spark plugs are fouled if it started at first (unless they just had a really weak spark??). Any other idea's? Theres one plug on the back of the block that is hanging down, but I don't see where it could go, its a black wire on the upper left (driver) side of the block. Also, when I did have it running the gauge showed no oil pressure (main reason I shut it off).

nope, he didn't have time to, I just took a volt meter the shift control plug on the transmission and figured out which terminals needed to be crossed.

Re: Started, ran rough, now wont start

Well the guy at autozone was completely right, oil smelled like gas and I took out the spark plugs and they where gunked up w/ oil and gas...so I replaced them, changed the oil, and while I had the intake off I cleaned that out too, was black inside, now it shines. Anywayz it started right up and runs great!!!!!!!!!!!!!!! WOOHOO!!!!!! and the 5-speed shifts great tooo!!!!!! but I need to do some more clutch line bleeding then it'll be mint! GO ME!
