The car shut off after driving a distance of i say 4 miles with no oil. The auto part store sold me the wrong oil filter and from the time i started the car the oil filter popped loose and i was losing oil. Didn't notice that until the oil light came on and now I'm trying to get it back going. Engine cranks but don't start. I tried it until the battery gave out on me. I had to get a new battery since the old one was bad couldn't recharge it. Next i tested for spark and compression. Spark i tested with a plug in the wire and the spark is weak but all four do fire. Compression i sealed the spark plug hole with my thumb and couldn't stop the air from coming out. Compression seems fine to me. Sprayed starter fluid in to the little hole by the throttle body and also tried spraying into the throttle body it didn't start. Couldn't check fuel pressure its no where to hook it up at that i know of. I replaced oil pressure switch, camshaft sensor and crank shaft sensor. Now i got the ignition coil off and the resistance on the primary is 0.8 ohms and 12.77k ohms. Also when i read for codes there is none.
