The last several weeks have been 50-70 degrees and only a few nights getting into the 40's, the truck won't start unless plugged in but is fine starting the rest of the day after I get it started in the morning. But there was several weeks where I was working 12 hour days and even sitting out in 60-70 degree temps the truck either wouldn't start (without a super small shot of starting fluid, I know big no-no) or was very difficult to start
Ok basically I've checked or what I know the following;
Glow plugs/undercover harness replaced two months ago and tested harness connector (think they all read .6 if I remember right)
cps replaced two weeks ago
stancor gpr two winter old but tested this morning and still working (although made the mistake to see how long it's energizing gp's but can test that in the morning)
When replacing the gp's I also replaced the injector O-rings I was very careful and not damaging them but who knows maybe I did.
Fuel filter/ oil changed under 2000 miles ago
One thing I didn't check was to see if I was getting oil drain back out of the reservoir
White smoke at startup, but clears and doesn't smoke after warmed up and it seems to run fine with no missing, loss/burning of oil
batteries/starter checked and good
not sure where the fuel bowl heater fuse is and not sure if that would make any difference anyway
Any suggestions on what to check next/again?
when checking the reservoir what is considered low?
Thanks for any suggestions, I really don't want to have to take it to a shop as funds are kinda low
