Won’t start in cold or damp conditions

I found a couple “u-toobs” on this subject.

This one I found short, to the point and confusing, but explains the problem:: https://www.youtube.com/watch?v=GVnYc0V8Tg8

THIS gentleman is Much Better at education and presentation…..but He has a “jumper-wire w/L.E.D” ….to sell to you from his website. I didn’t need his product…. just needed to get to the appropriate “pins” on the TIPM and make my own “jumper wth-Bosch-relay”…. Regardless, it’s a good way to understand the problem. https://www.youtube.com/watch?v=HcV5oAF1hM0

THIS red-neck just got back from diggin’ up ginger-roots in the woods…but if his daddy had not wasted his life in prison…he would have had enough family-money and talent to become a heart-surgeon… Anyway, this fellow gets serious about replacing that tiny OEM relay on the board itself with an end-product still looking like OEM. (Not the way I’d do it…but 4-stars for a real education by a courageous fellow country-boy.) :

And THIS shop gives you the PN’s and resources to DIY if you wish to buy the $20 part off Amazon and “Git ‘er Done!” : (notice THIS guy’s prob. was the pump running Continuously….but the exact SAME repair is also for the pump relay which fails to run.):

(The only thing I”d do different is at approx 20-mins…where a pin is removed from the plug so an unnecessarily-complicated splice can be performed..when all that’s necessary is Cut the Wire…then strip and splice the added wire into it… avoiding unnecessary disassembly of a Complicated plug.)

Thank you all for your help !
The TIPM fuse relay seems to have done the trick for the most part . Every now and then there’s still a hiccup but it’s better than before .

I don’t know how so if a mod could delete my thread I’d appreciate it !!

When i was a starving student in a cold climate area I improvised a block heater with a drop light. Worked decently. My first thoughts would have been battery, cables or posts but you seem to have that covered.
