abower1 0 Posted October 7, 2016 Share Posted October 7, 2016 i have a 2007 mack granite with the mp7 motor. we purchased about a month ago. changed all filters and fluids. last week we had a hard start issue and found it to be the cracked filter housing. yesterday when the truck was idling it just died. no restart. it will start with a spray of ether. when just cranking, its not smoking at all. we have checked the fuel filters, changed oil sensor, cam sensor. the dash oil pressure is reading 0, hours arent showing up, and the codes that are up are peal sensor, road speed sensor, cruise sensor, and one other which i forgot. the ecu connections are clean. i hope someone can help me, my next step is to have it towed to mack....
