The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

I had the same problem with my '05 F350, it's the Fuel Injection Control Module (FICM). My dealer replaced it under warranty, and even picked up the tow!!!!!!!!!

SOURCE: running fine. Died and wont start. Cranks fine

can you hear the fuel pump kick on when you turn the key on but without crancking the engine? Generally the fuel pump will prime for about two to three seconds when you first turn the key on. if you don't hear it that's probably the culprit. If you do hear it it may be a bad pump. also should check to see if you have spark. You can do this by removing a plug wire and using another spark plug. Ground the plug to somthing metal and have someone crank the engine (making sure you are not touching the plug or metal) You should see a spark while cranking. Good luck

SOURCE: 2000 v10 ford f350 wont start with out either

If the crank sensor circuit is malfunctioning, then that is your problem. The code does not mean that you must replace your crank sensor. (sometimes it means this, sometimes it does not) The code means that either the crank sensor CIRCUIT is out of range or the crank sensor cannot SYNCRONIZE with the cam sensor. There is a whole lot more to diagnosing a crank sensor circuit than simply replacing the crank sensor. Proper diagnostic procedures need to be followed to locate the exact cause of the problem.

99 f250 v10 auto 4x4-cat converter imploded,

The fuel pressure sounds too low. Is it multi-port injection? Check the fuel pressure against your specs for the car and engine. MPFI systems usually require 40-50 psi.

I replaced the fuel filter on my 1995 F350 ford dually. It ran ok before, but now the fuel pump does not provide enough fuel for the engine to run above idle speed. It starts, runs for about 15 to 25...

Usually on a fuel filter there is an arrow indicating inlet (making sure it was placed on correctly). Can you purge the line by cranking the engine (safely) with out the fuel filter ?. Did you purge the fuel rail ?

F350 Super Duty Diesel 2005 suddenly died while driving.Cranks fine but wont start.Help

that's good but it still doesn't rule out a leak in the high pressure oil system. When you turn on the key do the injectors buzz like normal? Usually 5-10 secs
