Cougar just stopped running

Last year I noticed my car lights kept flashing I didnt know what was wrong with it. I kept driving it like that for a few weeks. I noticed my brake lights wasnt working anymore so I had my brother 'fix' them (he says he didnt touch anything yet) and the car just quit. After that it wouldnt start. It hasnt started back since. It cranks over great. the starter is good. I have replaced the alternator, computer, crank shaft sensor, coil pack and it wont fire. All the lights come on. My brother said the plugs arent getting fire. the plugs work. The fuel pump works. I need help!:frown:

when your check engine light flashes it means you have a miss. Mine is doing the same thing right now. And i cant figure out how to fix it. So if find out an answer please let me know so that i dont have the same issue as you ended up with. My car is my baby and i have a shit ton of money invested in her. So please keep me posted on your problem. oh and by the way... misfires cause compression issues. So check your compression. what i cant figure out is WHY its misfiring.
