Ok, I picked up this 84' Chevy CUCV with the 6.2 in it. I followed ya'lls instructions and fixed someones wiring gom, when they tried to convert from 24v to 12v. I've got that all fixed and I've got the motor turning over rather quickly but have nothing happening. Is there a way to see if the glow plugs are working?? The truck only has 39K orignally miles on it, but I know these motor eat glow plugs. I tried putting a little diesel in the intake and nothing happened, so all I can figure is there's no spark. Please let me know if im going in the right direction and what else could I try????
