fd problem

[zxrazorxz]

so i have a problem with my fd its been ongoing for a month now and i cant seem to figure out whats really going on.
anyway heres the problem when i came to a stop at a stop sign the car stalled on me and would not restart.. it took me about a week to finally get it started again and it ran decent went into boost fine and boost ten pounds so after running it for a while to clear out all the gas and oil from the engine i parked it at home for the night.i went out the next morning to start it..and all i got was cranking it seemed like it wanted to catch and fire a couple times but it didnt.
so i got it towed down to my friends shop and unflooded it again and i made sure i had a blue spark so this time it started but it couldnt idle .. i figured you know.. it just got unflooded so thats normal.. so i drove it around a bit again.. and after about 30 mins of driving i tried puuting it into a little bit of boost.. i couldnt even get to 5 pounds of boost becasue all it did when it entered boost was backfire like crazy.. i took her home and parked her for about an hour and came back outside and i know theres a fuel cut while holding the throttle open all the way so just to make sure i did that to start it and it fired up no problem i went downtown to renew my insurance and came back home and parked it for the night.. came out in the morning and all i got was it cranking and trying to catch but it wont.... i really dont know whats going on.. the guy i bought it from said it wasnt running a fuel filter.. do you think its my injectors?.. or somethien more serious? compression is 90 on all rotor faces by the way..
any help would be awsome!
thanks
