HeavyEquipmentTech :

Hi my name isXXXXX will tr to help you. Check your suction line for restrictions from the tank yo the pump. Check your lines for any dry rot or cracking. Once you are certain there are no leaks or restrictions, and your problem exists..... replace/rebuild the pump as long as you also verified the fuel shut off is working properly. Let me know if you need further assistance. Thanks for using JA

JACUSTOMER-w8h01egr- :

CHANGED FUEL FILTER / PUMP.... HAS FUEL TO INJECTORS...WE SUSPECT ITS MORE ELECTRICAL RELATED........

JACUSTOMER-w8h01egr- :

CHANGED OIL PRESSURE SWITCH WITH ONE WE KNOW IS GOOD

HeavyEquipmentTech :

It the fuel shut off solenoid working to open the fuel in the pump for starting? Make sure you have power ther at the fuel shut off and it is actually opening up the fuel for starting.

JACUSTOMER-w8h01egr- :

ALREADY CHANGED THE FUEL FUEL SHUT OFF VALVE...........STILL DOESN'T START
