Hmmm, as you've got 1 popping, theres really not much that can possibly go wrong as you're building the pressure. Sounds like either delivery valves, but unlikely that it'd stop one popping, or air in the system.
Thats not a vane pump issue btw, if it was vane pump then it would be all injectors, or none. Im not saying that the vane pump wont be shagged, but thats nothing to do with why you have 3 poppers down and 1 fine.
Assuming you're priming the pump properly with diesel.
