When i start the genesis 7.7 it will idle great runs good at 1/2 to 3/4 throttle but if i run at full throttle for more than 50 yards or so it dies, acts like it runs out of fuel and wont push fuel through the line even when i hold my finger over the exaust, if i let it sit for a few minutes it starts like a champ but still does the same thing over and over, Im new at this and dont have a clue, putting in new glow plug today to try that, any more suggestions?
Couple of things to ck. Sometimes they got some locktite in the exhaust pressure line fitting. Run a wire or something thru it to check. Check the O-ring on the tank cap and make sure you push the cap down tightly. Check that all fuel lines are tite and not against the head , etc. Have you messed with needle settings at all yet ? Is the truck new or what ? Also is this with a full or half tank ?
