Thank you. Found out my problom and it only gets worse. Glo plugs work now. Still wont start so i think it needs a rebuild. It has 267k on stock motor

 

Is it taking a long time to pull fuel up, if its warm dies it not wanna start back sometimes?

 

Once its warm it fires right back up but if its been not running for like 6 hours takes a lonnnnngggg time

 

Fuel pump, cracked diaphram thats whats wrong with mine.

 

check your fuel lines..... thats the usual suspect in that kind of issue... I replaced all of them with Gates Bio Guard fuel line... got it from car quest a whole roll for about 65 bucks.... never ran this good before

 

I replaced all of my fuel lines. Presure checked them and everything so idk if that would be it
