if a 7.3 does not start??

[melmount]

Just checkign for info, If a 7.3 dioes not start, we can unplug the icp? that will set itto default. If it starts then, replace the icp? If it still does not start, it could still be injector not getting enough psi, right?
bad hpop?
do hpop's fail? Or is it all mechanical there? Example, just loose an o ring or something? Which causes pressure loss? What can go wrong with an hpop?
thanks

Yeah you can unplug the ICP. HPOP failure is very rare though it does happen. Make sure you are getting fuel. Smoke when cranking? CPS OK? IDM fuse OK? UVCH OK? Fuel tank got fuel? Fuel Pump operating?

where the icp on these? early 99?
Would the uvch set a code?

Didn't you replace injectors recently? If so did you get it started after doing so?
