The OP stated the engine starts and goes up to 3000 then promptly dies.

With a dead primary fuel pump...since the engine starts on both pumps and runs that way a while until the ECT comes up to a certain value, it won't die until the ECM cuts off the secondary pump and that does not happen immediately after start.
