While I was driving pulled into a driveway my car stopped and will not come back on. It rotates but will not start. I replaced the battery and the ignition coil and thats not the problem. What could be the next step to solving the problem.

Do below might lead you somewhere

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

ATTN: leomnr2008,

Check your fuel pressure if its within specs if okay clean out the idle air control valve and EGR/PCV valves and test the TPS and MAP sensor to include the fuel pump relay and fuel pump and oil pressure sending unit.

I have found the problem with my car and it might be helpful for you to check it out the pickup coil in the distrubtor mine is falty and the car tryes to start but then fails after. The pick up coil is easy to check.

First disconnect the EST ( electroinic spark time) connection this is the black and tan wire just to the left of the blower moter as you look at it then disconnect the four pin connector at the distrubtor control modual not the two pin fron the coil, check for spark if you get one then the pick-up coil (AKA ignition coil) is faulty and needs to be replaced.

If you dont get a spark the using a DVOM(digital volt ohm meter) disconnect the two pin connector at the distrubtor and check both pin for voltage the should read battery voltage if they dont then you have a short in the two pin gray connector at the coil. You will need to fix this
