Cold. no start!

mpowerstroketwins08 · Nov 13, 2014

I'm having trouble with my truck not wanting to start when the temperature drops outside. I've found that if I jump in and put key to run open the door, lock then unlock the doors it fires right up. I've had it plugged in overnight fires right up no problem. It seems to happen when it sits outside unplugged for a period of time

I'd say the glow plugs are not working. Same thing happen to me last year. All the GP's were shot.

Did you replace them yourself

mpowerstroketwins08 · Nov 13, 2014

Is it hard to do

mpowerstroketwins08 · Nov 13, 2014

It doesn't crank till I mess with the locks. Is that the same thing as you

glow plugs are easy to swap but i doubt it is that. 6.4's hardly have any trouble starting in the cold.

what is the pats light on the dash doing? seems more of like a security thing to me.

also-what is your battery level like?

The red lock light flashes. 11.5-11.2 is the battery level. No codes come up

That's the pats light. Something is up with the security system

I'm gonna try switching to my spare key see if that helps.

So another cold day no start. Reading the owner's manual the pats light is flashing as it should to indicate the engine is enabled. Now I'm thinking it's the glow plugs. I'll try switching in some new ones hopefully that's it. Any suggestions for the glow plug exchange tips or tricks

A few times I forgot to heat the glow plugs in 25 degree weather and it still fires right up. I doubt that's the problem

Weak batteries?

mpowerstroketwins08 · Nov 17, 2014

Changed batteries. Another cold day. It started 2 mins later bellowed smoke. Cylinder 7 misfire. Cylinder 7 contribution/balance codes came up. Cleared codes runs fine
