Hi,

When you turn the key, does the starter engage and the engine fails to start, or does nothing happen?

If the starter engages, it could be a few different things. For example, a faulty crankshaft position sensor or low/no fuel pressure. If the starter doesn't engage, then we could have a weak battery or an issue with the starter circuit.

Let me know exactly what happens. Also, if you haven't already, I need to confirm the battery is good. Here is a link that explains how to load test a battery at home without tools. Do this and let me know the results.

I will watch for your reply.

Take care,

Joe
