5177 Fuel pressure switch I have the 5177 kit. Sprayed it one and now the fuel pressure switch is not allowing me to spray. (Second solenoid not opening) I changed the switch out and I still have the same problem. When I jump the connectors the system sprays perfectly. I don't foresee it being the fuel pressure because the car runs great with no leaning. Any suggestions. 
Some of the FPSS aren't adjusted correctly for the system. I personally don't use one and on a stock car don't see the point. They are a pita IMO. There is a screw on the end of the switch under the black grommet that can be adjusted by turning it. I don't know the correct procedure for this maybe someone else can chime in.
Suggestion: ditch the switch.
