Odd fuel/throttle issue

[KMW-NWXJ]

Well, after two months it's started again. We checked codes, and it's showing a code 76. The chart I found says: "Fuel pump bypass relay circuit. Need specialist or dealer diagnostics"

When it started I was quite a ways from home so I got to feel it out pretty good. Idle is fine. You have to rev it up quick to get going without stalling. And it absolutely won't start without holding the pedal to the floor.

Then once you're driving, if you are smooth with the throttle it does fine, but if you punch it quick you get a lurch as it completely falls on its face for a second and then takes off just fine. It kind of acts a lot like a carburetor with a bad accelerator pump.

Anybody know what the fuel pump bypass relay circuit is?
