I was driving around all day yesterday. The motor was performing well.

Got in to start it this morning glowed it then when it fired up it immediately revved real high and started to climb. I shut it off immediately and now it will no longer start. The starter will turn it over but it will not fire.

Last night I re-attached the oil pressure sender wire and put a new gasket on the side cover of the injection pump. But that was all I did.

I noticed that the glow plug light (since I put in this "new to me engine" stays on a lot longer than the old engine.

What would cause it to rev like that? and then not start back up?
