Can you turn the ignition key on without cranking the engine over to see if you can hear the fuel pump in the tank run for five seconds? Here is a guide to help us get started:

Yes, I hear pump running and there is pressure in gas line will check with a gauge tomorrow but it did squirt fuel out. Getting spark of and on what concerns me is while cranking one minute it sounds normal next time it cranks kind of slow almost like its out of time. Occasionally it spits back up through the throttle body (air cleaner box removed).

Can you please shoot a quick video with your phone so we can hear the noise? that would be great. You can upload it here with your response. Does it sounds like you lost compression? Let take a reading of a few cylinders to see where we are at this guide will help

No, it sounds normal cranking then it will sound like it is cranking slower like timing has jumped making it spit up through throttle body.

Yep, it sounds like the timing has slipped a compression test will confirm the issue. You can rent a gauge for free from an auto parts store in most cases.
