New here, slow start

Hey guys, I'm new to the forum, recently bought my first diesel. I have done a search for this issue, but the threads I found either didn't have quite the same problem or suggested a solution that I've already tried.

I purchased a late 99 F250 EXT Cab 4x4 a couple of months ago. Just over 130K miles. XL with a manual transmission. Love the truck. Pulls everything I want it to and is fun to drive. When I bought the truck, it had been sitting for awhile. In 2004, it had 114K on it, and like I said, it's now just over 130K. I got a great deal on it, and budgeted to put some money into it. It turns over great and starts up after 3-5 seconds. Not a long time I know, but my brothers 7.3 fires right up. I figured I would get to know my truck a little better and do some work that may not have needed to be done because it had been sitting. I replaced the batteries, the GPR, all the GP's, and the CPS on top of doing new tires, new brakes etc. It still doesn't fire right up. Cold outside, warm outside, after driving 200 miles and then stopping for gas, doesn't matter. It's always takes a few extra turns to fire. Any suggestions?

Also, anything else that it's just a good idea to replace after it sitting awhile?

1999 F-250 Superduty XL 4x4. EXT Cab, short box, manual transmission. MBRP 5" Turbo back. Programmer ordered.

Mine does exactly the same thing. I haven't figured it out. I've cleaned out my fuel lines and my fuel bowl. I've done almost everything I can think of. I've just learned to live with it. But if it needs to get fixed, I'd like to know, too.

Install a gauge and watch the fuel pressure at startup. The fuel pressure regulator, on the bowl, has a spring, and oring on the piston. If the oring or spring is not working properly, fuel pressure can drop drastically. The pump comes on with the wait to start, then shuts off, once pressure is reached. The pump does not restart until truck starts. If pressure is dropping , would cause longer start.

At startup, try turning key back off, then on to re-energize fuel pump before turning over, see if it makes a difference.

I tried re-energizing the fuel pump. No joy. I'll put a fuel pressure gauge on it next week. Appreciate the suggestion.
