I'm not going to get in any deeper, someone else can explain it if they want.

Good luck getting it running.

See ya around the water cooler.......

Good chance the injection pump is worn out.

Try pouring water over it and attempt a start when the hot no start occurs-if it starts the IP needs attention.

Adequate cranking speed is also needed.
