sumtin wrong with the car ? ? ? ? ?

driving home one day my car started to run ruff like it was out of balance or missfiring, and sundenly shut of it will crank over and will not start, the injectors work, the camshaft timing is correct, all cylinders have a compression between 175 185 psi, but i think the ignition timing is bad and was wonderin if theres a way to check when the engine doesnt start, the rotor in the distributor cap is good so any help would be nice too find out what went wrong ?????? coil possibly went bad :banghead: :screwy:

Sure the coil could have gone bad. . .any time a car doesn't start you always check to make sure it has gas in the tank, fuel pressure @ engine, battery current, & verify for spark. If you tell us which one the 4 is missing then we will be able to assit.
