ok the truck had a burnt up glow plug relay module, after we repalced it , it comes on and clicks for about 20 seconds, with each click it does power the glow plugs,,,but the wait to start light only flashes once when the key is turned on, on this truck with the gpr is it supposed to click once and stay on then click off , or is it supposed to clcik click click for like 20 seconds? i know its wired right its fool prooff, we also repalced all the glow plus and now have replaced all the injectors,,, once the truck starts (with a lil shot of either) it will idle fine and dosnt have much exhaust smoke, but if i step on the gas it has alot alot of white fuel smoke, ? any ideas? talk to me?
