Help Needed 99 SD 7.3 cold start problems

[rudolphvan]

Greetings fellow enthusiasts, snows coming soon and recently my truck is a little hard to start on the frosty mornings. Thinking of checking glow plugs and buying a set on ebay...they seem cheap, have any of you 7.3 owners tried these plugs, they say they are OEM. The Ford dealer in town wants way too much. Suggestions anyone?

How does the glow plug relay look?

First, I would check your batteries. Have them load tested individually to make sure they are both strong. Also, make sure your connections are clean, and corosion free.

If they battries are weak/bad, replace them BOTH.

After that, yes glow plugs would be a good place to start. Stick to Motorcraft glowplugs only! This is one place you dont want to try and save money. I would be leary of some ebay ones...

Good luck!

Thats what I was thinking. I wouldn't want to buy parts like that for my truck off anything other than a reputable site/web store.

X2 rammertide , I changed all of the glow plugs to find that the relay was bad. The relay is the same as an old ( 1966 or so )starter solenoid.

advance auto part number for the relay is "gpr7"
thats 17 dollars too. Its slightly different then the original with wire placemsnt but they fit. It bolts right in place. Its not that ord part number but the internals are the same. The correct part number one is 40 something but internally the same.

Or get a kick azz relay from Mouser and never worry with the POS stock ones again. This one is GREAT and alot of others have them also. VERY HEAVY DUTY!
