Engine stalls while driving

When it won't start Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!

If you smell gas, check your oil level too, gas can be washing the cylider walls and filling up the crankcase...not good, this can and will damage the engine! Check the pigtail connector on the crank sensor, it's on the lower part of the motor on the passenger side by the bottom pulley, take it off and put it on again you will feel it click. This is a problem on these cars and my be your issue. A new sensor is only 18.00 at autzone.

Don't forget a simple vacuum leak can cause hard start, also the idle air control valve! Get a can of spray Throttle body cleaner, start the car and spray around, pay attention to vacuum lines and manifold, if the idle changes, you found a leak. You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs!
Keep the spray away from the exhuast manifolds. Fire hazard.
