While driving the truck backfired, shut off and will not start?

Hi,

Does the engine sound normal when it is cranking? For example, does it sound the same as always or does it seem to spin faster? If possible, record it cranking and upload it for me to hear.

Next, I would like to hear it cranking before proceeding, but have you checked for spark and fuel to the engine?

Again, I would like to hear it first to confirm the timing belt hasn't failed, but that is up to you. Here is a simple test. See if it 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 I would suggest checking for spark to the plugs.

Here is a link explaining how that is done:

Let me know.

Take care,

joe
