hi
thanks for your reply
I went to a hobby store and bought the whole harness kit (it was really 5 bucks + tax) that goes on to the truck and replaced it. I even got a couple of new glow plugs (thinking that my old plug was worn out or something). still the same problem, my revo or 4tec won't start but as soon as i disconnect the blue wire and plug in the glow plug warmer, starts it right away.

dunno what to do now... or is ezstart just not strong enough? as i've read on diff. posts, should i just cut off the blue wire and just rely on the glow plug warmer?
thanks
