First make sure the transfer pump is moving fuel. Crack the fuel line at the pump inlet. Cycle the key verify fuel flow to the pump. Retighten.
Crack the injector lines at the cross tube at the head about a turn. Crack #1 for sure plus 3-4 more. Which ever are easiest to get to.
If you crank and get zero fuel spraying. Anywhere. The VP44 has failed. It is very common to fail with no codes. But there are a couple of VP death codes.
