hard cold starting

[tomcat]

I've got a '99 f-250 powerstroke 7.3L that doesn't like to start on cold mornings (below 40) w/o plugging in the block heater. Glow plugs? Appreciate any help

Probably so. What do you mean by hard start. Does is spin over more than 2-3 seconds after waiting for the wait to start light? Bryan

It could also be old/weak batteries or a shaky GPR that's on its way out...

Thats why I asked for more specifics before saying forsure, help me out here.

Absolutely not--I thought my job was to be, at best, mildy irritating to you Mr. Whatadaddy Moderator Sir...

Subscribing....I had a tough time getting mine going ysterday morning. Seemed to be running on 4 cyl. and dying. No good. I had to give it gas to keep it idling. I figure that I have a bank of GP's not getting juice, but I am not sure how to see this. Anywho, I'll sit back and and see what the knowledgable say.

Don't give it gas!

Yeah, duh, maybe that's the problem I knew I was going to get a response on Freudian slip. Old habit, I will try to keep it from happening again.

Hmmmm, only running on 4? I would look into the under valve cover harness on the side you believe to be dead. That whole side may not be getting fuel if you shorted out a UVC harness.

As already mentioned tomcat, its probably either one of three (or possibly a combination thereof), Glow plugs, glow plug relay and/or batteries. Tell us what you have done to the truck so far and we can probably point you in the right direction.
