tryed starting my moto today

well after fixing some problems with my regulator(had the main line going to the retuen line port) i finally got fule going into the injectors(i think) but my fule peressuer gage did not read anything just kinda bounced around.the moto fired really qiut then turned off as i let go of the key. so i dont know if it becuase its not getting any fule or if the wiring is messed up on my ignition switch. she sounds mean just for that split seconed it fired need all the info you guys have wanna get her running tomarrow!!!

Sounds like maybe the lines are not bled yet, or you damaged the regulator when it was hooked up backwards. Did you try several key-on cycles to run the pump enough? Or, jump 12V to the gray fuel pump prime wire by the PCM to run the pump longer. You should eventually get pressure. Engine won't run without good solid fuel pressure first.

Gas in tank, right?
