I have an 08 6.4 powerstroke. I just recently got the truck. Drove it a week and didn't have a minutes worth of trouble. Couple of days ago I took my son to school, came back to the truck, started it put it in drive and it died. Sat a minute, started it back, drove home fine. Go to get back in it a hour or so later and started it. Went up the road and the traction control light flashed then abs,then check brake system and the truck went into limp mode. Brought it home and cut it off went to start it back and NOTHING. Wont crank won't do anything. The theft light pops on along with every other light that they put in them. It does have an h&s mini maxx tuner but the screen is blacked out and I can't read codes. I bought a cheap scan reader at auto zone and it reads u0155 and u0073 and it shows where I have 8th cylinder glow plug bad. Any help would be greatly appreciated because I have looked non stop for a reason for it doing this and can't come up with anything.
