MS2 Idling with only 1&3 cylinders?!? 1.6 '93
I installed MS2 to my '93 1.6, and car starts and idles with only cylinders 1&3. I have toyota COPS.
- I can see spark in all cylinders when car is idling with extra coil+plug attached to harness.
- Today I also tested injectorclip signals with lightbulb to injectorclip, one by one. I cranked (coils not connected) and found bulb glowing in all 4injectorclips.
- I can see that 2&4 is not working, because when idling, I can remove clips from 2&4 coils without affecting to idle.
I'm confused, what the ***!! Suggestions how to continue troubleshooting?? I still suspect that engine gets no fuel to 2&4 cylinders..

Your car is likely wired for sequential injection already. Mine was a California car so it was. Check if 2Y and 2Z are populated, if they are you need to run leads from those wires to INJ1 and INJ2. I cannot remember which goes where. I had the same exact issue!
If only 2U and 2V are populated, then check your leads in the megasquirt. There might be something wrong with the INJ2 circuit, which drives Injectors 1 & 3 on a batch injected car.
