Injector? Lots smoke - doesnt like the cold!

I have a '03 PSD 6.0 F250.

Its got 131,000 miles on her.

She runs great - as long as the morning temp is above 60 degrees!

The morning start is horrendous! Hard to start, makes a ton of racket, blows alot of white smoke (just at initial start), shift points are greatly extended, RPM's barely climb - doesnt want to accelerate.

But 10 minutes later - all is pretty well.

My mechanic has a 7.3 - loves fords and PSD's - he is baffled. No codes. But he said it appears the engine is only firing 6-7 cylinders upon first start. After that - after a good 10 minutes - the engine runs fine.

Maybe injectors, maybe injector computer.

My question - why is it so rough only when the temp starts to drop? Please tell me its something simple and not too expensive!

Do you have the newest replash for the "cold start fix"? Ford came up with a new flash (the second one) for this. Go to Ford and get it.
Might have them do a power balance test too. Could be a lazy injector or two with 131k miles.

yes

clay is right. The latest reflash is for that. But if it keeps going after warm up an injector or 2 are probably gone. But i would put my money on the reprogram.

It only struggles "pre-warmup"

After it warms - it runs great!

Was thinking though, I know the injectors are problematic especially in 03's and 04's (I have an 03)

I was told by Ford "You must have gotten one of the good ones!" as these are my original injectors - and have had very little engine problems.

Would new injectors be a worthy investment - even with a reflash? If so (new injectors) which ones?

New injectors will cost you a small fortune. A reflash won't. I wouldn't replace injectors unless they are proven to be bad. As far as which ones, they only have one factory replacement for them as far as i know.
This reflash has helped countless 6.0 cold start issues...even older ones that used to start fine and then started acting like yours is now.

injectors

You dont put them in unless you need them. You probably dont. The reflash should only cost you about $65 or so. That should take care of the problem. Injectors are $240 each.
