Message	I pulled the plenum off almost a year ago to replace the injectors because the car wouldn't idle for damn. But a whole-house remodel sidetracked me and the car sat in pieces. I finally found the time and got new 95+ style injectors and the JWT fuel rail adapter kit, put everything back together, but now the car won't start. Everything is exactly the same as when I took it apart so I'm not sure if it's an electrical or fuel problem. According to JWT, the injector pigtails don't have a specific polarity requirement, though I did ensure I was consistent in keep the thick and thin injector wires from the engine harness go the same side of each injector. I used butt connectors as I plan to pull the motor to replace the turbos, but will also replace the engine harness with a brand new one. Fuel pressure seems good; got a face full of fuel when I pulled the fuel line after the fuel filter. Car has only 82,000 miles, so everything is basically original, albeit old, brittle, and hardened. 91 TT MT
