Hmmm. When it finally fires up how does it run. Does it slowly come to life. Smoke. Or just crack to life like everything is fine?

Check your glow plug controller. Volts shouldn't be more than .3v (I believe) difference across the 2 big posts when the relay is engaged. These motors will stay warm inside for a long time. You could also plug it in for the night and see if that helps.

Will do i need to grab a DMM thought i had one but i dont, I only imagine the smoke is from try to start it and not succeeding because anytime after that there isnt any. If im correct the posts should show like 11v?

Maybe it was a poor connection between the pcm and harness. Good luck. Did you have it plugged in last night?

I plugged it in for the glow plugs and I have a feeling it was a bad pcm harness connection

Probably wouldn't hurt to check your gp situation.

I'll check the big posts tonight. I can only imagine the glow plugs are good they're all brand new but that's always a chance. Assuming to check them I need to remove my valve covers?
