Hey folks.
I have a 70'ish Ford 4500 that I rebuilt last year. It has always started right up if it is 60 degrees f and up but was balky below that. It is a 201 3 clyinder diesel.
I put a 1200 watt tank heater on it and it helped quite a bit although if it was below freezing it would take a minute of cranking before it started.
I bought a thermostart and installed it in the intake and plumbed it into the injector return line.
I mounted a momentary switch wired to the ign terminal and found through trial and error it likes to be energized for about 70 seconds before cranking.
20 degrees f. yesterday and it fired almost immediately.
Does make a bit of a whoosh when the thermostart lights off though.
Best $25 I have spent in a while.
Now if I could get rid of that little miss at high rpm/no load.
