I have a 1998 Dodge Ram diesel that will not turn over. I put fuel in it today drove home, parked it and then later moved it. Got back in it and it will not crank. It will turn over and try to crank but it will not start up. I have had no problems with it and this is the first time this has happen. Any suggestions on what it could be?

 

Did you by chance move it and park on an incline? If not I'd be looking at fuel pressure or rather make sure fuel is reaching the injection pump. 12 valve or 24?
