So first a little background. I have a 2006 6.0 with 117,000 miles on it. I knew it was about time to change the EGR
cooler and oil cooler and had the parts ordered. Well my FICM
ended up dying on me and so I went ahead and sent the FICM
in to be rebuilt and changed out the oil cooler, egr
cooler to aftermarket with tubes and put it all back together and installed a coolant filter. The truck wouldn't start and I wasn't getting any faults running scan tool on it. Everything was showing that it should start. Ended up having it towed to the dealer. They called and said according to our computer it should run. I told them I knew that and that's why it was in their shop. Well he asked the Ford Mechanic hotline and someone told him to remove the glow plugs and watch the injectors. All injectors on drivers side were bad so they changed them out and test drove it. On the test drive 2 on the passenger side died so I had them change all 4 on that side also.
Well a month down the road I noticed an oil leak. When I got to looking into it the leak was coming from beneath the oil cooler housing. I pulled it apart and the gasket on the oil cooler housing was leaking and had a small spot in it that had the leak. I replaced it and put it all back together. Now the truck will not start.
I am getting codes P0264, P0267, P0270, P0273 and P0282. I have double checked the ficm
plugs and all are tight. All the injector plugs seem tight. My question is should I pull them all off, clean them with electrical cleaner, apply some dielectric grease and put it all back together? I pulled the batteries and had them tested and they tested good but just a little low on the cold cranking amps.
