Hard Cold Starts

Been working in MD and have had a few issues. Few months ago had the fuel bowl heater short out and now with it in the 30's in the morning the 7.3 is real hard to start. Normally taking 4 to 5 cycles of the GPR before it will turn over. And, once it does getting white/gray smoke.

I took the truck to my local Ford guys and here is their analysis. Glow-plugs in #2 and #8 are bad. And, clogged/gummy fuel injectors. To replace all 8 glow-plugs and injectors ..........$5500.

Kick in the teeth is I am sure I can replace all of these myself if I had my truck back at my house in FL. Of course it doesn't get cold enough to have these issues in FL.

Let me know all thoughts and options. Also, if anyone has recently replaced both how long it took them.

Thanks everyone!!!!!

Fuel bowl heater won't matter on starting.
The GPs stay on for almost 2 minutes after the WTS light goes out, running or just key on.
Don't listen to the dealer. How do they know the injectors are clogged? Doubt they know at all.
First, find the sticky in the general 7.3 section on how to test your GPR and GPs. Then go from there. Might just be a bad GPR. If you wanna replace GPs, just do em all, and replace with Motorcrafts. Just have to pull valve covers and there they are.
Also, oil. What weight are you running? A 10W40 is gonna help over a 15W40. But a syn 5W40 is always best. Since the HEUI system uses oil to fire injectors, clean, well flowing oil is very important. When the oil is cold, it's hard to fire the injectors.
