SR Swap: Spark in #1, but none in # 2, 3, 4 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So ive pretty much completed my sr swap, but Im having a huge problem getting it started. Its getting fuel and air, but it will only spark on the #1 cylinder. All coil packs are good because i plugged them all into the #1 plug and they all fire. I tested the ignitor per FSM and its fine. Ive also double and triplle checked the wiring. The only thing i can think of is the ECU. its a #61 ecu for an auto sr20det redtop. Any info would be great. thanks

Hey, did anyone get back to you through email? i'm having the same problem except its only with #1. did the same thing of switching the coils and its not the coils, my friend who's working on the car said it might be faulty injectors, so we're gonna try that this weekend.

funny, friend had the same problem you did, Khmerguy618. his problem was fixed by replacing the injector in #1 and changing out the faulty coil pack.

mr2turbo, check your coil pack harness. it can also be ECU. also try swaping around the injectors.

how would messing with the injectors help get spark on other cylinders? My problem was that i was only getting a pulse to the #1 coil pack. All my coil packs worked off the #1 plug and my ignitor was fine. It turned out my problem was the ECU. I got a new one and it worked fine.
