49 Degrees and already barely starting...

Well it got down to 49 last night, and today my 7.3 barely fired. After one cycle of the glow plug is cranked slower than a Farmall M. Second cycle and it barely fired. Smoked out the shop! I just put 8 brand new Motorcraft glowplugs in it, and the left bank has new Injector/GP Harnesses. Bad solenoid? My wait to start light comes off pretty quick. i know i'm due for injectors orings but could that really be a cause? Even on a 65 degree day I get a little smoke on the start up. Its not oil, i barely use any and it smells of unburned diesel, I've wedged my face in my exhaust a few times! Any help appreciated!

I'd look into the GPR and see if its functioning properly.

you said "cranked slower..." are you talking the starter is barely turning the motor over?

I had the same problem ,after putting in a block heater,new batteries and glowplug +relay,I about gave up until someone told me about a gear reduction starter,I checked into it and ordered one through DB Electrical,it only cost $106.95. I installed it which weighs about half the stock starter,I could not believe how fast this thing turns the truck over ,amazing,I get a smile on my face everytime I start her up.Best money I ever spent.This is the site :sales@dbelectrical.com check them out great co. to do business with.

You might need new batteries if it's cranking slow, and replace the gpr.. But still if there is alot of white smoke your injector o-rings more then likely need replaced.

how long does the white smoke last? it could be injector o-rings.

honestly, if its cranking slow and your batteries are good i would lean towards the starter. i too got the gear reduction starter (imo, its 3x as heavy as the stocker) and WOW. i can start 49* no glows. imo weak batts or weak starter. you could try jumping the relay, but that wont make your starter spin faster.

Do you have a part # or a direct link to the correct starter... I could not find a listing for a 7.3 or a 444

Thanks
