02 f250 5.4L cranks no start. I have tested and replaced everything I can think of sometimes x2. Long story short- I had a hole rubbed in my fuel rail hose replaced fuel pump x3. New fuel filter, cops, injectors, ckp, cam shaft sensor x2 a new external relay for fuel pump and still no start. I did the instrument panel test mode and d262 came up - comm. Bus error . pcm no comm. with one of the modules. I have everything but no tachometer. Fuel pump primes but no start. Any help would be appreciated!

 

Starts with the basics: Fuel, air, spark. At least one is missing. You need to identify which in order to make real progress (unless you plan on more guessing and happen to get lucky).
