Greetings all-So I am new to this website and joined after reading some really good remedies to the usual 6.0 issues that come along with my 6.0 F250. So here is my description for my problem. About a year ago i had the hot start problems,(So i came here to read up) I replaced the STC fittings and all four plugs to the new ones. After last years winter i had taken my truck to the dealer and had the glow plugs replaced on the drivers side(FORD said they were bad after testing). I had the radiator flush done as well. I change my oil every 5k to 6k with approved Motorcraft parts from the FORD dealers. Lat mont i also replaced all 8 injectors as the dealership said 7 of the 8 were bad. Now coming up to my problem. My truck will not start. I had went out to my truck to come home from work and the truck had a slight vibration throughout the start and ride. The next morning i went out to warm it up and went back inside, only to come back out to find it was shut off. I tried to restart and nothing. I replaced both batteries as they were old and no juice(tested at FORD) as well as replaced both fuel filters(Motorcraft). I read through the website and pulled the ICP sensor and the truck fired right up(Idled rough) after there were no previous starts. I plugged back in and no start again. I pulled the ICP sensor and there was no oil but replaced anyways. I replaced and plugged in and it started up but ran really rough with black smoke for about 30 seconds and stopped, Tried again but it would not start. So then I read here once again that I need to check the IPR. I pulled the blower to get to the IPR and the screen was clean and no tears. I am about to reconnect everything as I have just purchased a scan gaugeII. I know this should have been the very first thing I purchased minimal to try an pin-point(lesson learned, trust me). Any input would be beneficial and appreciated.
