Driving my car and it was performing like usuall then I turned a corner and for some reason it lossed it's power and the idle dropped. Seems like the engine is running really rough now. Usually it would shift at 7000 now it shifts at 4000 grand and there is no power. Anyways was driving it home and all of the sudden it started running normal again. Ended up driving to the store and on the way there it ran rough again but then in a block, it died and would not start. Got it towed home and found that the negative battery cable came loose off of the engine block. Well I tightened it so there was a good ground. It started fine. No problems but it runs really rough still. Well I let it sit in my driveway till I had time to work on it. Well when I finally went to work on it. Now it won't start at all. It will crank over but doens't fire. Could I possibly have a bad ignition coil or Module that went bad?

Hi Krazemofo, Welcome to 2carpros and TY for the donation

Hard to say if its the ICM or the coil-Do below to determine if its a fuel or spark problem and get back with some results we start here.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

Well your welcome for the donation!

Well I got my little helper over and I checked for spark. And I don't have any! So where should I go from here to check. It has no distrubuter so what do I test now? To test the input voltage. Should I get voltage at the connecter when the car is on with keys in it?

Check and test the crankshaft position sensor and the ignition control module.
