Easy Cold starts, NO GPR

Well, with so many treads on hard cold start I wanted to ask a questions.
Is there any damage to the Glow plugs or anything else if GPR is unpluged/broken. Mine is busted at the connectors so I disconnected it totally.

It only takes a crank or two to start it Up, there is barely any visible smoke out of the exhuast.
Currently there is only 37K on the engine(original).
The temperatures here now around 44 F.
I will eventually put a new one in when I find long lasting one .

This is what I am going to do when my relay goes out again, I think (it is only my opinion) that leaving GP's out of service for long periods of time causes carbon to build up on them and then makes them difficult to replace because the element is larger than the hole. I would imagine that those individuals who break plugs off in their truck, that plug has not worked for a while for one reason or another. I would get the system back up and running soon, doesn't need to be today, but don't wait a couple of months either, you might regret it.

That's pretty amazing that it starts easily at 44f without a GPR.

BTW: No damage will occure with it disconnected...just more difficult to start, well not for you though.

Its a quick and easy repair.
Seems the GP system along with the EBPV system start to have a use at 46* and below. Above that they are not needed. Just my findings.

I always thought that I had good working Glow plug system, until I realized that dash voltmeter was not indicating disengagement of the GPR.
after testing it out I knew it was bad.

I know I might get in trouble when it dips below freezing but I could always jump the GPR terminals.

Only my opinion but, the part is cheap it,s easy to replace and (the wimpy stock one) lasted this long so I would just do it!

Cut off the connector and splice the wires to the GPR. Doesn't matter which posts you put them on.

I am not sure what is wimpy about the stock GPR. The current one on my truck has been on for five years and 150k miles, but it could break today.

Wimpy= not reliable, high fail rates, high currnet draws, terminals snapping.

I too thought I had a reliable GPR, since my truck had no problems starting at around freezing temps. until I found out.

Well,
It has hit 31-35 F and around that here at night. And starts Up fine.
If it has been sitting overnight or more that 20 hrs than it starts on the second try.
After I swithced to White bottle of Deisel Kleen than all it takes is one try.
Pretty cool, I think
Mast be good compression in that engine.
