P1293 no start, IDM problems
what's up guys, having some problems with my 7.3....i'm kinda at a loss here so any advice would be helpful.
my truck started off running rough, felt like a cylinder or two was dropping out. so i parked it at my uncles and it wouldn't start back up. hooked up my modis to it, had a ton of codes. one being a 1298--internal IDM failure--so i got a new IDM for it (OUCH!!!--expensive)...all the codes went away except i'm still throwin a 1293 code for high to low side open right bank(funny because motoralldata says 1293 is for the left bank). i've ohm-ed out the harness from the IDM to the injectors on BOTH sides of the motor. from the idm to the valve cover gasket itself, the gasket connector itself, and the UVC harness. nothing came up. i replaced the UVC harness on the right side for good measure, with the updated version from international. even though the left side ohm-ed out fine, next up is replacing the left side UVC. i've checked the pins and connector at the IDM for broken or bent pins. i've checked the injectors---pretty nonsensical that all the right side injectors would go bad. i don't know what else to check. what else is there in that circuit that could cause this code???
i'm at a loss! my only thought from here is that i got a faulty IDM.
will repost when i get the left side UVC in.
any advice welcome. thanks!!
