Hi,

In most cases, a crank no start is either an ignition-related issue or fuel related issue. Also, a failed timing chain can also cause this.

Does the engine sound normal when cranking it? If you feel it sounds differently, record it cranking and upload it for me to hear. It could be a timing issue and normally I can tell by listening to it.

If there is no change in cranking, here is what I need you to try. First, see if the engine starts if you use starting fluid. If it does and then stalls, we know it is a fuel-related issue. If there is no change, then suspect an ignition-related issue.

At that point, I will need you to check for spark to the plugs.

Here is a link that explains how that is done:

Let me know what you find and if you can record it, please do so.

Take care and Happy Thanksgiving.
