Crank no start

I'm sorry to say that the fact you felt the need to change the crankshaft position sensor leads me to understand that you haven't done any proper testing here. The crankshaft position sensor is likely just fine and replacing it could cause more variables than positive benefits. Spark, Fuel, air flow, emissions controls, engine timing, engine compression, exhaust flow. Anti-theft system features. These items are the only things to create a "no start" situation. Check into all of them, or employ someone to do so. Have you started using a new key recently? www.repairpal.com/repair-shops
