Constant flashing CEL while in diagnostic mode indicates that there are no codes stored.

I'm not positive on the best way to check the fuel system operation on a 1JZ, but if it's anything like the 7M and it has a similar diagnostic port, you should be able to jump a wire from FP to B+; with the ignition key set to "Run", this provides the 12V positive power through the fuel pump circuit and you should have a constant running fuel pump until you turn the key off or remove the jumper wire.
