Hello all. Truck is a 1995 F250 and has 111k miles on it with no mods at all. Truck will start sometimes but with a very rough idle/loping and white smoke out of the exhaust. I found a burnt pin on the driver side front UVCH pigtail so I replaced the pigtail and put in a new UVCH and connectors to the GP/injectors. I have also replaced the CPS (tach wasn't moving while cranking) and a new ICP because FORScan gave me a P1280 code for it, that code is no longer showing up. I pulled out the IDM and shook it to see if it had water in it and it didn't, tested all the wiring on the IDM using the test procedure at gbreman.com and everything was within spec except the power-to-injector-ground on the right bank was 3.1 ohms where it should have been OL on my DMM, left bank read correctly. So after installing the new ICP tonight I was hoping it would have fixed it since it cleared the code but it hasn't. So I ran an injector buzz test and it came back with a P0282 #8 Injector Circuit Low. At this point I don't know what else to check or do and I am by no means a mechanic but am willing to try anything else. Would anybody have any suggestions on where I should start next? Thanks for any help.
