f250 89 injectors 2-3-6-7 are not polsing
so i live out on a ranch about 33 miles to the nearest city. i use my f250 89 for crossing rivers in the winter time. its kinda my life line. i tested for spark and it was working great. i did a water test to see what injectors weren't firing found that they were 2-3-6-7 all the rest are working fine, i flipped the wire from a working injector to one that doesn't and it seemed to work fine that time. so i tested for voltage there is power getting there. i believe its could be wiring because i looked at the wiring diagram and it shows that the injectors in question are wired separate to the ones that do work. i have all but given up dose any one have any ideas as to what it could be? its a f250 custom with the 5.8L engine gasoline 4WD. i desperately need my truck with summer cumming on i have 1100 acres of land that i cant manage without it. any help would be greatly appreciated thanks all.
My guess is that there may be an issue with the wiring that feeds power to injectors 2,3,6&7. Follow the wire harness looking for corrosion or abrasion along it's path.
turns out that i found the issue the injector wires on 2 &3 were grounding out.because a pack rat decided to chow down on them. ended up pulling the plenum off and soldering the wires. tomorrow ill put it back together and pray that it works ok thanks for the tips.
