BNR S3 now a miss developed?

why is your fuel so dirty? I'd drop the tank and clean it out while you're at it.

have you done a boost leak test? can't say it's not one without that but I'd you're getting 12 psi on the itfp that's a fuel issue for sure
 
Everything else on the log stayed consistent except for the hpfp pressure. I'll boost leak test it when I put the new pump in.. just to be sure. It also sounded like the pump kicked on then cut off after like 2 seconds.. the sock was clean as a whistle this time.
 
just bench tested my facotry itfp and it works fine. maybe the resistor or fuel pump relays??? buy why only a 1 cell dip?
 
If you only have 12 psi when the itfp is in the car something is not right. It may not be building pressure or there is a restriction or blockage in the line.
 
still have the 1 cell drop in hpfp pressure. installed the plugs the tuner recommneded and its still present.
