how about checking that the glow igniter is fully charged then once it has been charging for atleast 12hrs(just to be sure) pull the glow plug again to check it
What elevation are you??
You might wanna try loosening eht glow plug just a bit and then tightening it once it starts.

You might want to get good pair of leather work gloves

There's not much to keep it from running Keep trying

Good Luck!!!
