    does the motor run when you request function? do the valves magnetize when at the same time? is the small black orange wire under the hood hooked to the negative battery terminal.

    what type of truck? who installed it? maybe a picture of said unit.

    2005 f350. checked all grnds today. Motors runs and each of the valves got 12v when tested while motor ran. Pretty much ran through the mechanics guide. Still haven't performed a pressure test. Gotta find someone capable of that.:mechanic: Just soooo frustrated, bought the damn thing to make life easier and nothing but headaches. Tested all valve cylinders and found 1 not working and installed new one today.
