Engine misfire

The connected end wasn't tight where it connect to the coil and it is tight now I think the pig is good how do I test the coil and spark plugs?

The connector to the coil was loose on #2 coil I replace new spark plugs and when I disconnect the connector from the coil the connector broke the engine was starting before I did that but now it want start no firing no fuel pump coming on and when I disconnector from the coil the connector broke the engine was starting before but now it want start no firing no fuel pump coming I don't no what could have happen if the connector wires touch each other will that cause the engine not to fire and fuel pump not working? What all I need to check to fix the problem why it not firing and fuel pump not coming on? Please help.

Yes I check for spark there is no spark, the fuel pump is not coming on when turn the key to run, I check all the fuses under the hood thoses that I seen I didn't find any blown fues, is there another fuse box on this car and where it is locateded? I want to get this car back running. What could I have broke and what I need to check now what all the things that can cause the fuel pump not to work and no spark? Do this car have a ignition module on it? What control the fuel pump and the firing system?

Engine misses very badly in hot weather. Tachometer bounces erratically. Cool weather it runs good. Last mechanic threw parts at it hoping to get lucky and fix issue but no success. New fuel pump, swapped out computer, new distributor, plugs and wires etc, no change in performance. I think IAC or dirty injectors or mass air flow sensor. What do you think?
