how to cut fuel on a diesel gets complex , no ?
and how you do it , can cause unintended bad things.
starving fuel pump is bad (some need it to be lubed, so coasting with no lube, oops)
2 stage pumps, one in tank and the injector pump on motor. easy does it.?
and did you know some injectors will not close off , if there is no fuel pressure behind them. Including direct injection.
you really need to study the design of your diesel system first before , guessing.
get the EFI injection schematic first , look at the inputs and outputs and see what is available to play with. there will be cam timing scheme there. we exploit that.
