I have a 7.3... had the same problems. I replaced the cam shaft sensor twice...second time I used a ford part. Didn't fix my problem.... I replaced the ICP sensor and it would not start. Put the old one back in and it started, but ran rough. Swapped the bad sensor, put it in and it ran like a charm. The next day the truck would not start. Any idea what could cause this? I am going to try yet another sensor for the ICP. This blows my mind how it worked yesterday and not today. Thank you in advance

[@KITS_Auto_and_Truck_Repair]

Hip Airbrush you should check your injection pressure, sounds like you might have a defective IPR or bad high pressure oil pump... get a pressure gauge and install it on the ICP sensor opening, crank the engine and see what kind of pressure you get

Excellent troubleshooting video. My truck was running fine when I shut it off 2 years ago. Upon starting it recently, it started, ran rough and died. Now, no start. The ICM was full of water, swapped it out. Replaced the cam position sensor, fuel filter, IPC, and put a gauge on the HPOP. Finally towed it to a diesel shop, and 6 weeks later, I owe more than the truck is worth, and it still isn’t running. They’re telling me that it needs 2 injectors, and if one stops up, it can prevent fuel,from getting to all of the injectors. Am I being had by this shop?

[@KITS_Auto_and_Truck_Repair]

nclaytonc I wonder why they replaced all those parts!!

[@GenerationsLodge]

@@KITS_Auto_and_Truck_Repair in all fairness, it was I who replaced the parts before I finally decided to take to someone else. The Injector Control Module was full of rain water, so I condemned it. The IPC, cam sensor were cheap enough, and the fuel filter had 148k miles on it. I talked at length with the mechanic yesterday. He was a Ford tech for a dozen years, and trained other techs on the 7.3, 6.0, and the 6.6. I was impressed by his knowledge and thoroughness, but the bottom line is we’ve spent a lot of money and it still does not run. The only parts that don’t check out at 100% are 2 injectors (#4 and #6). Right now, I’m waiting for the shop manager to come back from vacation so we can agree on a not-to-exceed repair cost. The no-start condition is being blamed on the tank of bio-fuel that has now been in the tank 4 years. I didn’t know that bio-fuel has the same issues as ethanol gasoline when it sits too long.

How to you test the 12v supply side of the injector driver for a shorted driver with a test light? I connected the test light to battery positive and and touched the test light to injector driver 12v supply to injectors. The test light was flickering. I know the light should only flicker on the control side when the pcm pulls them to ground. But it shouldn't flicker on the supply side, positive to positive should it? Did I do this right? Have I confirmed supply side injector driver shorted? Need a second opinion to confirm I did this test right please.

Melody Carrero it sounds like you have a wiring issue, check power and ground at the IDM, if you have power and ground for the injectors at the module , you should also have it at the heads, on both sides... be careful checking those wires, there is 200v on them/ the other possibility would be the module itself,
