Default 1987 12v cummins no start issues

i know that most people post here about there first gen trucks. but im here with some issues coming from a 1987 koehring feller buncher. the engine is a rotary pumped 12 valve almost identical to a first gen dodge. the machine has been sitting for about a year now but it ran perfectly when parked. its got fuel in the tank and it will turn over great and run on ether but it wont run on its own fuel. there is fuel going to the injectors but it doesnt seem like very high pressure. any ideas?

I'm pretty sure those have a fuel cut solenoid on the pump you need to make sure it's getting power
