friends 05 lly was knocking/ smoking under load, balance rate on #2 was +12

he swapped the injector out drove fine for about 15 miles, knocked on his way back home.


i went to take a look the next day, started and ran fine for 5 miles then died, will not restart. only making 200psi rail pressure. the return line on the injector he swapped is leaking (lost the oring)


tried unplugging fpr still only 200psi. any ideas? just wierd how it ran fine for 5 miles with good rail pressure up to 22,000-23000 (stock truck etc) and now nothing
