Update:

Never did any vavle adjustment yet because it really doesn't make sense to.... Plus i just dont think it would just die like that and show zero effort in wanting to start after many times of cranking. We did however do air compressor psi flush back to clear any filter clog in the tank.

My dads machnical friend came by the other day and they tested the fuel lines coming out of the fuel injector pump unit and none fuel was came out. Looks like he needs to rebuild or buy a new/used injector pump which im am sure is a bunch of money.
