Please help 1997 7.3
i switched to stage 2 injectors monday night, started the truck it wasnt on all 8 cylinders and smokeing heavy so i unplugged each injector found out witch two were not fueling and pulled them cleaned them put them back in the truck was running on all 8. seemed to be running good. so i went for a test drive and got about a mile and the truck seemed to loose all power and stall. hard to restart but once it restarted it would run ruff then clear up so i would turn the truck around to drive it back home and it would do the same thing well i let it run on high idle for 10 mins it seemed fine reved the engine and seemed strong so i took it back up the road went about 3 miles and it acted like it ran out of fuel and wouldnt restart.
i did the following to it,
ran the scan tool said crank sensor faul put the crank sensor in (rpm gage works)
new icp sensor
new crank sensor
un hooked the tw chip still no start
the hpop oil level is about 1/4 below the plug.
ran a buzz test on all 8 injectors all 8 worked,
im running out of ideas any help would be nice thanks
