Default International VT365 (ford 6.0L diesel) Issue

Need a little help from the 6.0L techs!!

My boss has a 2007 International MXT (UniCat) with a 6.0L Diesel that he uses as a chase vehicle for the BAJA 1000s. The truck only has 20K miles and had a leaky EGR cooler. We decided to install an EGR delete kit and did the head gaskets and studs to be safe. I was able to do the entire job in about 15 hours, but can't get it started now. Cranks fine, but seams to have air in the fuel system. I have cycled the key many times but just can't get it to fire. The glow plugs and injectors cycle when the key is turned ON.

Anyone have any tricks they care to share??

Thanks,

Scott

a long crank is normal after anytime the high pressure oil system is opened up....sometimes it seems like the bitch might not even start up...now assuming that there are no actual high pressure oil leaks, like the stand pipe and block off incorrectly installed, and orings new/ in good shape..you should be fine just keep cranking..as far as the fuel goes, i like to take the upper fuel filter cap off, turn the key to the run postion and fill the bowl..after its full reinstall the filter and cap, and the fuel system should be fine, unless you have a injector oring/ copper compression washer issue...if you did the oil cooler as well you have to watch for dirty oil/ dirt getting below the oil resivior and then it goes strait to the ipr valve and will cause a no start as well..the screen under the oil cooler is almost always torn..shit design..id say keep cranking but if she doesnt wanna fire up after a while id hook a scan tool up and look at you icp pressure...need 500 psi min to start..good luck!
