Ok, used a 9V battery, heard the click from the injectors, tested wires at injectors with test light (no noid avaliable) and saw a steady light on. going by what the manual says, a steady light on (with noid light) means a short. Checked wires going from ECM/COMPUTER found two out of three had continuity (were good) could not find third wire to have continuity. This electrical stuff really baffles me, friend of mine is helpin with it, but wanted to see if sounds like this could be an effective way to test, or if it might be right direction to go? to dark to continue. After two days of rain I put all wires back on, injectors, computer etc, truck fired up and ran pretty good for about 7 or 8 minutes then just shut off again. while running I noticed that one injector has a rather sloppy spray coming out of it, while the other looks to be fine. I hope this helps someone out there, cuz it is definatly confusing the heck out of me. thanks again.
