2001 PS not starting

[Texas7Stroker]

I have a 2001 F250 PS and has been running fine. 121,000 miles. Only mod is a chip set at 75hp. However, it did start a little rough yesterday morning. Today all it will do is turn over.

1) It has a new fuel filter (one week old).
2) Oil changes (One week ago)
3) It has a chip and I set it back to stock and no code but 603, which means it has a chip.
4) The tachometer does move with the long cranks, which I have been told means the CPS sensor is fine.

What do I look at next?
I really don't want to tow to the dealer unless it's an absolute must .

Replaced the CPS and Unplugged the ICP Sensor and still no start.

Anybody have any ideas? If not then off to Ford Service it goes.

Couple-a things...

Does the WTS light come on? (shows the computer is running)

Is there fuel in the fuel bowl now? (open the drain level to check)

Fuel pump runs? Fuel refilling filter housing?

Could the fuel gauge be giving a bad reading? (are you close to empty?)

I have drained and filled the fuel bowl twice without issue,
and i still have 3/4 tank of fuel left.

I have done some reading about a fuel pressure pin getting stuck or something about a bent spring causing the pin to get stuck. Where is that located?
