1997 Chevy Cavalier Popping and fire from throttle body

Check fusible links on starter solenoid
Check for codes
Do a fuel pressure test
With key on you should have check engine light on, do you?
Check if security light on and blinking
And if so turnkey on for about ten to 15 min

Checked links. If I remember correctly most of the codes were misfires. Ok, another reason I want to mention that why we called the electrician was because when my father-in-law was installing the starter, he accidently forgot and put one of the ground wires on the starter solenoid. So after it didn't fire up but cranked we pulled the car to a mechanic down the street. Also when we got there the intake was flooded with gas up to the throttle body. Mechanic immediately said that we might have messed up the computer by doing that after he checked it, but after it was checked by a good reliable electrician, all wires and sensors were working. The check engine light is on and the theft light too but not blinking, its steady on. Tried the key on for about 10 to 15 min and still nothing, cranks but wont fire. If we use starting fluid, it will just pop and start a fire at the throttle body. Here are my last options im thinking before taking this car to the junkyard for giving me a headache. Im going to do a fuel pressure test, going to change ignition coil housing, and check the timing belt. Any other things I can try? Ive had this car for 2 months and hasnt even worked 2 days straight. Have replaced the motor, air compressor, starter twice, did a fulll tune up. I am frustrated here. Maybe its just bad luck since the previous owners friend died in that car, and it has three bullet holes, in different locations. None that would stop the car from working.
