Thanks guys! I have a weird update though:


Got in the car today and plugged the pump module in and it didn't automatically start making noise. The car started fine and then my ABS/brake and stabilitrak lights came on. Threw a code u0121 (Data bus, ABS module - no communication). Drove it like that for about 30 minutes, next time I got in the car the ABS & stabilitrak lights are gone, as well as the fuel pump issue. First time seeing this ABS stuff. The car has had the parasitic drain issue for months.


Will see what I can test over the weekend using the diagrams and check back in. Thanks again.
