Hi,

If it happened all at once, chances are either you lost fuel pressure or ignition spark. The crankshaft position sensor can fail, cause you to lose spark, and never set a code. Take a look through this link:

Here is what I suggest to start. See if the engine starts using starting fluid and then stalls. If it does, then we know it is a fuel related issue. If it doesn't try to start at all, then we need to check for spark to the plugs.

Here is a link that will explain the most common causes of a crank no start condition. Take a look through it as well:

Let me know what you find or if you have any questions. Once we determine if it is a fuel or ignition related issue, we will get you up and running again.

Take care and I'll watch for your reply.

Joe
