    V6 or V8 look at crank pulley, bottom front possible timing problem.Do you have fuel getting in to motor?
    Have you look at the fuel pump?

You got a 7.3liter diesel. First thing to do is make sure the oil is at the proper level and if its real dirty change it. Powerstrokes have to have correct oil level to start and it needs to be clean. Next I would change the fuel filter. If it still doesnt start you need to have the fuel psi checked it should be about 60psi key on engine off, 50-55psi running. If that checks correct you will need to hook it up to a diagnostic scanner and scan for codes, you could have an Injector Driver Module failure ($900), or a high psi oil leak in the system (to check that you need to look at the hi psi oil pid it needs to read 600psi to start. These motors are a bit complicated hope I helped some.

Chugs when driving at rpms around 1300 when accerating

Start with checking fuel pressure. Pressure must be at specs before looking elsewhere, like spark plug condition, air filter, air or vacuum leaks, throttle position sensor, etc.

1996 F250 powerstroke 7.3L keeps dying

It is sometimes difficult to determine exactly what is wrong with the 7.3L engines. Many times it is hit and miss for the do-it-yourselfer. It sounds like you are getting enough fuel at first and then fuel is being constricted. You might want to try changing the fuel filter. Sometimes debris becomes lodged in the fuel tank switching valve which would require cleaning the valve or replacing it.

1996 f250 7.3 powerstroke has rough idle on starts

it sounds like to that it is either worn/ old injectors,dirtly HPOP (high pressure oil pump) oil worn HPOP pump or dirty fuel filters or fuel. you can take truck to a qualified diesel shop and they can do a buzz test on your injectors and see if they need to be replaced with a buzz test the tester will buzz all eight injectors with engine off and you can hear the buzz of the injectors then it will go through and buzz each injectors individually in firing order to der determin witch ones are bad. the bad injectors will be alot quieter than the other and most testing equipent will show what they are running at. hope this helps.

The 7.3 power stroke is not tha bad sheesh its actually pretty simple ok let me ask some questions here ok lets start simple when cranking does the needle on the tach move to approx. 5-600 ? if not more than likely its a cam sensor in which case there is actually a recall from ford they will fix it free.... yes I said free :) if not my second guess would be the Idm they were notorious for getting moisture in them btw IDM stands for injector driver module and you can find a good reman unit online for 200 "use google" if you have a friend with a high end scanner hook up and watch engine rpm there and also do a "buzz test" no buzz = idm fail another easy thing to do is open the drain on the fuel filter bowl and turn the key on and crank for 1 sec is there fuel shooting out ? if there isnt check fuel pump well that about covers it good luck please let us know whats up :)

04 f250 diesel cranks but won't start

this is an oil pressure problem, either a sensor is not sensing enough oil pressure, or the high pressure pump is not building enough pressure(possibly leaking or head is leaking). this engine requires 450 psi minimum oil pressure at the injectors to actuate the injectors.
