fuel pumps dont seem to go out on Y33 as much as G50, probably less strain on it due to using only 270cc injectors vs 370.

In 97 they redesigned the FPCU plus they added a safety resistor from fuel pump to ground so that if FPCU failed the pump would still run enough to crank and cruise................problems show up as weak acceleration [fuel pressure drop].
