Why plug it into a block heater in the middle of summer I do not know. I am not the one that did it. But it works. Which is what makes it very strange.
This is not my truck I am the 4th auto shop that has had this vehical in the past year to try to figure the problem it has been to 2 other independant shops and the GM dealer.
So I am looking for new Ideas. Here maybe one of you could think of something everyone else hasnt already thought of.
And Seriously I would have it on a battery charger not that I PLUG it in. I mean when my customer came in and said he plugs his truck in the middle of summer to make it start I didnt say What are you plugging it into, I just said that is very strange and even though it is weird and strange he was right and it does work.
So obviously pluging it into a block heater is warming somthing up that makes it easier for the truck to start. now what that could possibly be I dont know.
But I have seen a similar thing on a Ford Diesel that had a fuel leak on the top of the engine. It would not start in the middle of summer unless it was plugged into a block heater. Somtimes things that should not work do work.
