starting problem when cold

[halter413]

Hi everyone, I have 95 7.3L I have problems starting it when the air temp is below 45*. But when it is pluged in it starts just fine. I have tested the Glow plug relay and it works fine. Although I did notice when testing there was smoke comeing from the underside of the rear wireing harness, one the passenger side of the truck. Anyone have any suggestions? Thank you and Merry Christmas, halter413

i have the same problem.the only solution ive found so far is diesel starting fluid one spray of that and it fires right up

thanks i wil have to try that untill I can get the glow plugs tested.

no no no no starting fluid is crack for a diesel. that is the worst thing you can do for a diesel engine. i would keep plugging it in untill you get the plugs tested. i have seen so many good engines just get wasted by using ether. test the plugs and post up the results and we can go from there.

I also have a hard starting 95 7.3 @ about 45 degrees. It also blows lite gray smoke and smells of blow by for a few minutes. Runs superior when warm and no blow by. Warm starts are fast and clean as a whistle. Idea's please.
Thank you
