Hey Fellas, My car cut off on me a few days ago while I was driving. When I attempted to start it again the engine sounded like is was halfway on. It was a low rumble for about 2 minutes and when I gave it some gas it shut down. Since then I have changed all of the spark plugs and wires and installed a new battery. The car still will not turn over. Any suggestion?

Could be a fuel or spark problem do below

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
