Random injector clicking, car backfires, dies randomly.
So about 3 months ago i got into an accident in my rx7, well i swapped over everything to a new chassis, car runs great but randomly dies, I've checked all of my grounds 3 times, changed the fuel filter, checked the fuel pump, injectors are fine, I think it may be loose connections on my injectors cause with the car just to the ON position i can hear my secondaries randomly clicking, and i mean random. Also the car runs great when it is running, whenever it dies it just cuts power out like its completely losing fuel. im not hitting boost cut i know this. It will die basically anywhere and any rev limit, its not the dreaded 2800-5000RPM hesitation. I've been trying to track this down for about 4 days now and im stumped. This car ran completely perfect before i got into an accident and now ive got this fuel bug.. Suggestions?

Your ECU should be an N332 or N333.
They are Turbo ECU's.
The N326 and 327 are both N/A versions
I am assuming that you have that S5 TII engine wired up an an S4??

you are correct! But like i said before the accident the car ran perfectly. the guys i bought the car from had built this car with the NA ecu on purpose. i think my TPS may be acting up got the UIM off now and im adjusting it according to the OHMS

ok TPS was off on narrow range reading 2.6 closed adjusted it to 1.1 lets see how this works, also clips on secondary injectors were broken so im going to order some new clips now, and possibly ground the ECU better

adjusted TPS car accelerates smoothly. didnt die or bog out when i went to test drive it. did a couple 3rd gear pulls, man this car is quick
but when sitting still in neutral still sounds as if there is a misfire somewhere on the secondaries

I see maybe it was the tps all along
well i just drove the car for a while around town and so far no stalling bogging out or random dying, the hesitation is still there but i couldnt see my tach since my lights are burnt out in my dash.. is there a way to adjust the full range on tps for an S5? i could only seem to move the narrow band with the adjusting screw underneath the TPS
