Im missing on cyl 4, im getting spark, got good compression, injector isnt firing, and i have no injector pulse. My question is I measured it at the ECU and its supposed to read 11-14V KOER, i got nothing, has anyone had this prob. i dont wanna just throw a ECU at it. any help would be greatly appreciated.
