1994 LS

changed the fuel filter this morning after the car had trouble starting... before if i had trouble starting, id beat the shit out of the fuel filter and the car would start on the next try.... so today i just change it and once i was finished, the car still wont start.... put like 10 gallons more into the tank, a can of stp fuel system cleaner... car still wont start. im about to drop a match and collect insurance.

any ideas?
