2005 Malibu Classic rolls over, but won't start
I have a 2005 Malibu Classic, 4-cyl. Several months ago, my car decided it didn't want to start for me. When I turned the key, the motor rolled over like it wanted to start, but it wouldn't fire. The first time it did it, I just left it in the parking lot for almost two days, tried it again and it started just fine. About a week later, it did the same thing. That time, the only mechanic within an hour of where I live came to get it for me. He kept it for four months only to tell me he found a bare injector wire that was grounding to the motor and he 'fixed' it. When I got the car back, I was pretty leary since I've never used him before - so I traced the injector wires and nothing. I think he just let it sit up long enough it reset itself again like it did in the parking lot the time before. I got in my car this morning and it started doing the same thing again. I really don't want to have to tow the car an hour to get to a reputable mechanic, so any advice would be greatly appreciated!
Fuel is getting to the motor. I checked by pressing the pressure relief valve, priming the engine, and pressing again. When I try to start the car, it rolls over just fine - and the battery doesn't sound weak at all. I've replaced the spark plugs & wires, fuel filter, and the oil & filter. Still no luck.
