More wiring issues

[Swifty1638]

So, after driving to the mall today, and everywhere else under the sun, the car was just fine. Then, on my way to a party tonight, the car starts ticking from under the dash. I guessed it was that MPI fuel relay (gold box under the radio area). I unplugged that relay, as my fuel pump is wired to a switch instead (battery to fuse to switch to pump to ground-on when the switch is on) but, with that MPI relay unplugged the car wouldn't start. I don't get why, as I thought I by-passed it, but I guess not. So, I plugged it back in, and drove around on it to, and now from that party. The car runs and drives as well as it did, but you hear that damn relay ticking away sparatically in the backround. Also, when trying to boost, the car breaks up badly around 4k rpm-almost wants to die cause it's missing. What could be going on, and anyone have ideas on how to fix/bypass that switch?
