If it gives me the 55 "end of test" code, is it safe to assume that the ECM is
getting all the power it needs? I guess it's possible that there's a wiring
issue that only cuts the power supply to the fuel pump. No matter what, I'll
check the voltage right at the top of the pump itself before pulling the old
one. 12V + no fuel = bad pump.

Good idea... I'll do that when I get a chance, so I can stop worrying about it.
To be honest, I'm surprised it hasn't bitten me yet (knock on wood).
Thanks,
