Ya, My truck HATES the cold....

truck is a 93 7.3 idi bone stock besides the soup bowl mod.

It was about 38 this morning and I didn't plug the truck in. I really didn't think it was going to start.
I plugged it in for maybe 20 mins.
I'm not sure how old but I'm told the glow plugs and relay was new. I also did an oil change about a month ago with rotella 15w-50.
I'm going to make it so I have a button in the cab to control the glow plugs. If that don't help I guess i'll be replacing the glow plugs.

Also the battries and alt are less than 6 months old.
Am I missing something?

Depending on the brand of glowplugs they could be bad withing a couple weeks. Autolite plugs will do this.
It sounds like you need to check each one with an ohm meter to verify if they are working or not.
If you have autolite, you should replace them with motorcraft right away. The tips will swell and break off in the cylinder. Possibly taking out the whole motor.
If your wait to start light comes on and off in just a few seconds, that could indicate bad glow plugs as well.
So 2 questions for you
1: how long does your wait to start light stay on?
2: does it start good when plugged in?

As stated, those two questions will in fact tell us whats up.

If the wait to start light comes on for a couple seconds or less, or doesnt come on at all and just starts flicking, your glow plugs are screwed.

I would plan to buy glow plugs, rockauto has the ZD9 plugs for something like $10.50 for motorcraft plugs (only motorcraft, or Beru plugs, nothing else!)

See those on rock auto.
Light stays on for 8-10 sec
It starts like its 80 out when its plugged in.

I did notice a fuel leak. The pump is new but something is leaking from it.
Loose line or something. I'm wondering if that has something to do with it.

- When its cold and I let the plugs cycle. If I just give it a little throttle it fires and dies. I'm wondering id that leak is making a small air pocket.

When its 40 here my light stays on for at least 30 seconds, if not a little longer.
Check your glow plugs for sure. you have a couple bad ones.
Then fix the fuel leak. Air will add to the problem.
sounds like your on the right track

That's normal. Once its done with the initial heat cycle it will click on and off several times after the wait to start light goes off and after its started. That's to help cut down on smoke when its first started.
The time that the relay cycles on is determined by the resistance it see's from the glowplugs. Less resistance= less on time. Bad glow plugs = less resistance.
An ohm meter on each glow plug will give you all the answers.
