boost4

I isolated an overnight battery drain on my S14 with redtop SR swap down to the 7.5 amp fuse under the hood for the EGI circuit. With the key out of the car, I can hear the ECU coming on when I replace the fuse after I pull it.

The car has a 255 walbro pump in it. I have had a lean issue under higher boost with my chip tune and 520cc injectors. Voltage was on the low side at the pump under boost, in the 11 range, but fuel pressure seemed to check out fine. So I'm hoping whatever this problem is that fixing it will rich my mixture up a bit too.

What wiring, relays etc. should I be checking next, and for what? One other thing is that my ignition switch is kind of flakey. The turbo timer and stereo dont come on until the switch is turned back from the run position just a hair.

Thanks for any direction here..
