Hello new here I have a 2003 Tahoe 4.8l started with driving home from work one day driving and it stalled out would start back up but would not drive more then 2-3 hundred feet had towed home figured was fuel pump replaced it Friday. Monday morning go to head to work make half way stalls out again will start won’t move. Towed home again replaced pressure regulator and fuel lines and filter. Hook pressure gauge up only getting 45 pounds so figure maybe pump is bad get another pump same thing 45 pounds relay replaced for good measure no Change will run for 30 mins to 210 temp then seems to stall out at this point at a loss and just have no idea what to do gonna check injectors but don’t have a check engine light on any help would be more then appreciated !!
