Cold weather trouble

[Im_Strokin_ur_Cummins]

I have a E99 250 that HATES the cold!! I live in Northern NY so it gets quiet cold, and my truck just does not want to start. I run glow plugs 3 or 4 times some times more, and wether it is 40 or -10 or colder it wont start. I have replaced #6 and #8 injectors put all new plugs in on that side as well, and a new valve cover gasket and harness. Still refuses to start I have to spray "Start you Bastard!" into the intake for it to pop on colder days and warmer days it usally starts after quiet a few cranks. Yes I do plug it in but that doest do anything for it no matter what the temp is.I usally have to resort to getting the battery charger or a jump on the really cold days. My dads truck is same as mine and will start regardless of being plugged in or not even on the -10 days after sitting all night. Any ideas on what my issue could be? Hauling a salamander out at 6am is getting old fast lol!!!

Did they all burn out? What were they throwing out for voltage?

I was having the same problem as you in Pa it never wanted to start in the cold. I switched to synthetic oil 5w-40 and i swear it starts like a new truck i don't even have to plug it in ever.

So, it was your intention to have us all play a Guessing Game with you is that right?

Why not help us help you, and include EVERYTHING that you've already replaced or checked so you're not wasting our time telling you to do things you've Already done..........

Had you gone through the steps in the Hard Starting & GPR/GP threads I pointed you to?

I have already gave you the stuff I have done, read first post.



As for the oil situation I dought it is that since the old man runs the exact stuff I run. For the relay I currently dont know how much its pushing since i dont have a volt meter on campus.

5w-40 will help but at 40 degrees a properly functioning 7.3 should have NO problem starting with 15w-40 in the engine. Light weight oil helps but it is not a cure all...
