I bought a use 2004 malibu maxx LS, when the prior owner had the emission test taken the check engine light stayed on and hasn't went of, also my service light comes on ocassionally

4th cylinder not firing

I have been having so many problems with my car...to where I'm not able to drive it..

2004 Chevy Malibu classic 03 engine.has a new fuel filter cranks but won't turn over.its not the theft system either

I cant find where the oil is coming from, possibly the rear main seal. If I start and let idle it doesn't leak, only after driving it around the block it starts leaking like a sieve.

what could it be, I would your help on what it could be or what should I do.

With my old car I could get the code by turning the key backwards 3 times and the code would show. My check engine light is on in my 2004 Chevy Malibu

I bought this car a week ago, replaced alternator. also dash lights are very dim and wont adjust , cd wont come out, the drivers info center has no warning messages . it just tells me service air bag...then car acts up it tells me low fuel then says 311 miles left .

The car stopped and it was the starter that was bad so we changed it out you put a new one on the battery died that's why we replaced it replace the battery and it still will not turn over the car. That's why we had everything checked

fuses are good . Could it be either ignition switch or body control module
