My problem only 34,000 miles. The engine may crank but not start.

It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. Remove an ignition coil with a spark plug in the rubber boot and the plug casing grounded have a friend crank over the car and see if you have spark. If you do the crank angle sensor is OK. It could be many things. I hate replacing parts without knowing they are bad. You need test instructions, There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
