Big thanks to you guys for the help !!!! Found my problem in the middle of reworking to underdogs write up. While plugging back in the fpcm connector come to find out I had some lose pins from de pinning the wires earlier. Fix that and Fire her up good to go boys !! Just need to clean up the wiring tomorrow and do some voltage test to see my gains. Thanks again guys!

Think where I am getting confused is to where fp+ goes to ? Off the pump to where cuz turkeylord write up shows it getting un pinned from the fpcm connector and pin 87 going to fp+ wire. Your saying 87 goes back to b+ and into the fpcm ? Correct ?

Yes Underdog I can data log the ecu and have a fuel pressure gauge in engine bay. Car had no issues before I touched the wiring. Wanted to upgrade the wiring for full potential of pump. I think I see my mistakes and will correct them and test again. Thanks again for the help

http://legacygt.com/forums/attachment.php?attachmentid=215305&d=1440504392 i have 87 going straight to fp+ and not going threw the controller is that maybe my problem ? i followed this write up http://legacygt.com/forums/showthread.php/upgrading-your-fuel-pump-wiring-4th-gen-213570.html

I'm pretty sure I have the wiring correct. Only question I have or want to double check with you guys is 86 wire on the new relay gets tapped into the red/black wire (b+) wire. Then that wire is removed from or cut before it reaches the controller ? According to the wiring print u guys have posted. 87 wire from new relay goes to the pump + side correct ?

Thanks for the help Scooby2.5 my friend has a spare controller im going to try tomorrow. Going to double check the wiring make sure it's good. I'll let you know what I find. Thanks again !!!

Hey guys followed along on all the post about the fuel pump rewiring. Finally got around to wiring it up. Followed exactly to the diagrams. Car fires right runs for about 1 min then dies. Noticed duty cycle at 100% on fire up and stays at 100% for fuel pump. Not sure what is going on at this point any help would be great thanks guys
