Ok i have a international 4200 with the vt365 6,0 in it which i hear is the same as a ford.. my question is the truck was running fine then one day it wouldnt start. it turns over but nothing someone said check the icp and unhook it and it will run in limp mode.. well i unhooked it and it did start in limp mode so i bought a icp. truck still will not start with new icp and its driving me nuts.. i just spent 30,000 bucks for this truck as a towtruck and i havent been able to make a buck off of it but have spent money to have it towed to my shop twice

 

What year is it? and is the ICP on the valve cover or behind the turbo??

 

its an 05 and its on the passenger valve cover

 

Did it start when cold then not want to start when warm?? just wondering if it started and ran till it was warm then you put new ICP sensor and it would not start. if that is the case then it could be a High pressur oil leak.
There are some tests you can do to try to eliminate some causes. You can test the FICM, there is a test procedure at top of the 6.0 section. You can also test the low pressure oil to make sure you are getting oil from the engine oil pump.

 

it doesnt seem to matter if it's cold or warm the first time it did it it was cold the second time it did it it was warm. and like i said i replaced the icp with a new one and it still doesnt start. il check the oil pressure and then the ficm . i changed the oil when i changed the icp. ill check back with my findings
