Having some problems with my 08 si. Stock k20z3 cx racing turbo kit, 1000cc grams injectors, grams 320 fuel pump, hondata 4bar map. During my etune the tuner noticed a issue with the fueling. After some inspection i realized injectors for cylinder 2 and 4 are not sending fuel. Both positive and negative wires going to injector have power for those 2 injectors. Which i know ground is supposed to get the signal from ecm to send fuel. The other 2 injectors are functioning fine. Ive checked continuity through my harness, continuity in the injectors themselves, checked my fuses and relay, checked my grounds. Anyone else have a issue similar to this. Really appreciate any help!!

 

Post a copy of your FlashPro datalog here. How sure are you that the ECU or wiring is the issue instead of a clogged or broken fuel injector ?
