Hello all, I have a 73 IH 354 diesel cav type injector pump. I was mowing and the engine revved up a few times and the engine died. I went through the fuel system, cleaned all the lines, put a new filter, cleaned the bowl,and put a new pump on the motor. I bled the lines to remove air and it still won't start. Took a little gas a and poured it on a towel and stuck it in the intake and it started, but won't keep running. Could it be a bad pump? no smoke, no missing, no banging or any type of engine noise. Any help or ideas would be helpful as i am stumped. Thanks in advance.
