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.
