Fuel pump controller? Your fuel pump only has one speed on or off. If u have high fuel pressure you need a new regulator. Or check for linked line under car where it might have came in contact with the asphalt. If ur pump is just really loud then it is on its way out. Walbro can be had for around 100 bucks.

Yes u are getting bad info only thing controlling your fuel pump is a relay. I'll let in on a Lil secret first if all give it a tune up plugs, oil, fuel filter, air filter then buy some PURE acetone from your parts store. Put half a gallon in with half a tank of premium gas. Drive it around a Lil bit then test if ya don't pass use more. I've seen it work on cars without catalytic converters. But never done it on a turboed car.. I'm doin a 1jzgte swap right now in my mkiii this is how ill pass due to it not having emission system on it.... but I live in Utah its just a Lil sniffer in the exhaust for a few mins. But im sure this will work for you
