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.

 

**** that POS man (sorry for the language) ive been around that dry kti for years, when it first came out. that think is crap for our cars, works great on low pressure systems
