Hello! Let's see if we can can work together to get to the root of your question!

Do you know what engine you have? Kubota , Duetz, or ?? Electric fuel pump from tank to engine?

Customer: replied 11 months ago.
No. I'm not sure which engine.

OK< if you open bleeder at the injection pump, and turn on the key, do you get fuel flowing from the fuel transfer pump ?

Customer: replied 11 months ago.
Can't find the bleeder. That is the biggest problem. I feel once I find it I can handle the rest.
Expert:  Curtis B. replied 11 months ago.

I'm thinking this is Deutz oil cooled engine.

Expert:  Curtis B. replied 11 months ago.

Looks like all the injection parts are on the opposite side of the engine! Will engine swing out?

Customer: replied 11 months ago.
Engine will not swivel

Do you hear electric fuel pump running when you turn on the key/ Do you see the high pressure lines going to the cylinder head? Need to locate the fuelline going to the engine from the fule pump, and loosen the line or bleeder and see if fuel is flowing. Was engine run out of fuel ?

Customer: replied 11 months ago.

Found the head, there is no fuel coming out
Expert:  Curtis B. replied 11 months ago.

You need to be checking fuel at the injection pump area, the place the high pressure fuel lines com from.
