New FSD, No glow plug now

[DaveHart]

What the heck did I do??? Ugh!!!!

My 94 blazer was stalling numerous times on my commute. Always started up just fine. I installed new FSD on FSD cooler today and when I jumped in to give it a try, no glow plug light!

I'm using the existing cord and left the old PMD on the pump. I don't think I put much stress on the harness. I even put a notch in the heat-shrink to give the ground wire more play.

Thanks!

I'm not real sure on the 94 but on my 99 the glowplug control/relay is on the back of the motor driver side. Also there is a number of wire conectors back there, I would start by checking both of those as while you were replacing the FSD you may have pulled a wire loose. Have you checked the glow fuse? Have you checked to see if they are getting power? Can you hear the click of the relay?
Hope this helps!
