What he said. No need to prime them. Do you have access to a rail pressure gauge? If the ECM doesn't see at least 2000 PSI it won't fire the injectors. I assume that the inj's are plugged in, wires in good shape, all the basic stuff has been checked? Any codes? One possibility might be a rail relief valve leaking or stuck open.the commonrails are self priming.
