Syrus Posted July 14, 2011 Share Posted July 14, 2011 OK, I have a start problem and i'm scratching my head on. any help would be appreciated. I'll start from the beginning, I have a 2004 STi with Perrin fuel system, CP piston heads bore over 100m, Manley rods, Precision Billet Turbo, 3 core FMI, and 2 leaking fuel lines. so, i change one of the leaking lines thinking that is was splash/spraying fuel on to the other one. two weeks go by and i realize that the other one was leaking as well. Now the first one was the feed line past the "T" leading to the left side fuel rail (looking from driver seat). I changed it and worked just fine. Then 2 weeks later I changed the feed line heading into the "T" and then the problem starts. It wont start after i change the line. I disconnected the battery, then remove old line and install the new line then reconnect the battery. and for a week and a half this is what i've done.... removed and replaced (R2); Fuel Feed "T" Fuel Return "T" Fuel Pressure Regulator Ops checked; Fuses (Engine Bay and driver seat) - Good coil packs - Good spark plugs - Good battery - Good fuel pressure - Good fuel line for clogs fuel rails for clogs fuel injectors for clogs correct fuel line installation - Good cam angel sensors - Good crack sensor - Good knock sensor - Good fuel pump relay - Good fuel injector relay - Good I've tryed over and over to start it, yanked on all the connectors/harnesses, checked for oil levels and fuel in oil, all fuses, relays (i think) and my Cobb interface shows injec latency, delay, and power. fuel pump is working and i have pressure. I put carburetor cleaner in the intake manifold to see if it would start and it did... for 10 seconds. So i then used Noid Tester on injector harness and it did not get a light off. Relays were good and I changed the map so i could see if the ECM needed a reboot. nothing.... so what can i do now? is the another relay or fuse? do i have to get a new harness?

lmdew Posted July 15, 2011 Share Posted July 15, 2011 I'd post this over at NASIOC.com. More in line with that group and the mods you've done. Link to comment Share on other sites More sharing options...
davebugs Posted July 15, 2011 Share Posted July 15, 2011 I'd post this over at NASIOC.com. More in line with that group and the mods you've done. Yep. Lots of good info and folks here. But not as much with newer and modified stuff. Good luck. Link to comment Share on other sites More sharing options...
Cougar Posted July 15, 2011 Share Posted July 15, 2011 You have most likely blown a fuse in the panel under the hood that supplies power to the injectors. Blown fuses are easy to miss and look good to most folks on the first pass. Link to comment Share on other sites More sharing options...
