First, I believe the manual says never use starting fluid on these engines, you can destroy your engine, did you prime the fuel filter? Check your fuel pressure, check your fuel lines to see if they are cracking and sucking air. There are a lot of causes. Was it blowing any smoke? How many miles? Post a signature so people can see what you have. I place the filter on top of the starter and fill it with diesel then put it on,never have used the primer.
