And after it sets over night i can open air bleed screw on pump has plenty of fuel running out but i see none at the injectors When it cranks over. Already had to replace fuel pump and shut off solenoid months ago. This problem started a couple months ago.

The only thing between them is the injector pump. Have you checked / tested the stop solenoid to see if it's working correctly.
Also when you replace it before did you install a new sealing washer?
What about the checking or replace the stop/load relay. if it's failing to energized or the wiring from start position to it.
Do you have the circuit diagram?

Í just looked at a picture of what I believe is your fuel pump 31S9401810, correct me if wrong, but I don't see a screw, just looks like a seal unit. Are you talking about the fuel filter assembly?
In Mahindra parts picture they also show a controller, I can only guess what it does but without a schematic not sure, maybe someone else can help.

Bleeder screw on injector pump. Solenoid is working and I did use new seal on it. Haven’t checked stop/ load relay. I don’t have a circuit diagram but can probably find one on line. Thanks help!!

If I understand correctly you've cracked the line at one of the injectors , cranked for a period of time and you still get no fuel ...correct.

The attach file might cover your problem or maybe not and some might apply while other not.

I'm a little late to the party but have you tried to cycle the plugs more than once before starting?

Believe you machine has the MHI S3L motor.

Had a similar issue with mine a couple years ago. Dealer stopped by and found crimp on wire connector to the glow plug bus was loose. Replaced the loose spade connector with a ring terminal. Said it’s a fairly common problem on the MHI motors. Also said the MHI motor really need the glow plugs even in warm weather.

Thanks for the info I will check the connectors.

Yea doesn’t seem to help. When it sits over night I have fuel at air bleeder on injection pump but none comes out at injector when I loosen injector nut.I’m assuming I’m loosing pressure.
