I nought this car not running I replaced the fuel rail, fuel pressure regulator, fuel pump relay, alternator, starter, and crank sensor but still no luck. It has fuel getting to it and spark. It turns over and attempts to start. What could it be?

I would check compression, and Fuel Pressure next,

. Test all under hood and under dash fuses with a test light or multimeter:

Be thorough, since it will save a lot of time and money.

. Check each cylinder's compression.

. Replace the Ignition Control Module (ICM).

If the problem persists, replace the coil packs.

The Service Manual will save Time and Money if you don't already have.

Could be a lot of reasons. Check with a local garage. Diagnosic fee probably less than the parts tried on the car already.

CHECK THE TIMING before you buy a lot of parts
