Turns off when runing and when heating it up in the morning

if it turns off it might be the MAP censor it happened to my 2001 dodge if not take to a Dodge dealer they will tell exactly wats wrong and how to fix it :)

i have a 1994 f350 diesel 4x4 the engine wont start

Check the starter. Pull it off and have it tested at your local parts house most parts houses will check free of charge. Also these 6.0's are known for injector problems along with oil pressure o rings going bad.

this is not right there should be a rubber grommet in cluster lens take out and press button with ignition on to reset light just like resetting trip meter

test glow plugs.

You have an air lock in the fuel lines

To clear it you will need to go to the point where the fuel line meets the injection system and loosen the nut on the joint .

Turn the engine over with a rag wrapped around the joint until fuel comes through, once it has soaked the cloth tighten the nut and try the engine.

If you are runing on diesel then there are a number of bleed points on the fuel lines which are designed to let the air escape in a controlled manner

hi,if your engine is a diesel engine,you need to check the glow plug system,it is necessary special in morning,then you have another problem,seem vacuum is leaking for engine not stop by itself,you can visual check if there is loose vacuum connection,ty

Broken hose

Check the starter, selinoid, and then the ignition switch if the motor will not turn over. If it turns over without fire check the ignition coil and then the distributor.
