Just repowered my Catalina 36 Universal mp25xp with a rebuilt. Starts right up but when I take my finger off the ignition it just dies.

Fuel pump is tied to the starter button. Glow plugs disengage upon release of the starter button, so not in play.

Not always.

Leslie,
Thank you for all your help. One more question. what is this sensor? Seems like there should be a wire connecting to it but there never was.

what is this sensor?

From the location, looks like a temperature sensor.

 

[LeslieTroyer]

That is you engine temp (water). Should go to your engine panel.

That is what I thought but I have this sender united that the temp gauge was connected to.

Those goofy temperature sensors often use a brass stud with a groove to hold a push on wire terminal by friction. This instead of a screw. The wire falls off easily and you have no temperature sensor. Hopeless design used over and over by many manufacturers.

So are you saying I have two water temps? One a push on and the other the screw type. Thank you

Sure looks that way.

Thanks, everyone for the help. I ended up getting it working. After replacing fuel lines, cleaning the fuel tank, new wire harness I still couldn't get the rebuilt engine to start properly. The company that sold me the engine told me everything was rebuilt and tested. Turned out that wasn't the case, I had the fuel pump rebuilt and it fired right up. County Sales and Service out of Ohio were too good to be true. Sad that they wasted so much of my time.
