Video. Wont crank weird sound

Please pitch in if you know what wrong. Im guessing no compression in some cylinder. Maybe blown gasket. Bad rings. Melted piston. Like i said Im not sure so please help.

Im not positive but to start the vaccum pump is loud and sounds like its about to take out on you. Look into that. The miss on startup is not good.. You want a nice even crank. But if you listen closely the starter does not sound right... Id replace the starter first being that its cheap and go from there. Moving forward- why the truck did not fire and start is another question. That could be a number of things that you would need a monitor for to make sure all the values/pressures all in line to fire engine.

It takes a minimum RPM to start and it doesn't sound fast enough to me.

Unless you had a generator running that was out of sight, unplug the vacuum pump. Get a couple of hot batteries and try again. Jumper cables won't cut it. If the starter still has the hiccup in it with hot batteries it may be toast.

How many miles? Does it have oil in it? Does it fill the fuel bowl? Any history on truck? Do you have the ability to scan for codes or view data stream?

Definitely a dead cylinder, an almost dead batteries and a worn out fuel pump. (oil doesn't look too good)

Of course my impression!

The ring gear on the flywheel/flexplate that the starter engages. You will need to pull the starter and turn the engine over by hand and look at every tooth on the gear.
