did the search cant find any answers. I did rx7-store ulimate fuel system upgrade and have power FC and all other mods to support this. The map is correct for the bigger injectors, all the resistors are wired in correctly i hope? and all the emissions are blocked off. Car will start if you spray fuel into the throttle body but still injectors wont open. Any ideas.........???

have you tried running a 12v source through the injectors to see if they click?

Will do. any other suggestions??

disconnect the injector and see if you are getting any pulse to them idealy with a noid light or be sure you are using a HIGH impedence test light to check for the ground switch and the steady batt power when you crank it. if no signal check how thw resistors are wired and ohm the wiring from the injector connector to the ecu with the ecu unpluggec. glwi
