[AT] 3 cyl diesel problems

[ivan]

     Helping a buddy out moving some dirt using a small bobcat excavator 
. He ran it out of fuel and thats when  the problem started .  After you 
fill it then you use the primer bulb . It will start up ,run for about 
10 seconds then sputter and die like its starving for fuel .  First try 
was a new fuel filter , the round spin on one bolted to the side of 
machine . No change . took off the fuel line where it goes into the 
injector pump and squeeze the primer ,fuel comes out .   He even tried 
grandpa's ,whack it with a hammer but failed .  Any suggestions ?    He 
said the engine is a kubota  3 cyl diesel . It was bought used 5 yrs ago 
and first tie its ever failed .  Thanks , Ivan
