i bought a 5500 4x4 the other day and i cant get it to fire up for nothing. no codes just a a pain so far. its asking for 6k rail pressure it is getting almost 2k when i try to start it. fuel is clean, no air and holding pressure when you pump it up. all sensors seem to be reading and nothing out of the ordinary. yall got any ideas?
