Default Cylinder 2 and 4 not firing

All of a sudden the car is running on two cylinders. There is spark but apparently no fuel. I did a little digging and it was recommended that reflashing the ECU may help the issue. I went ahead and reflashed it and the issue persists. Help I have to go to work in the morning

Wrong section. Need more info on your setup. What standalone are you running?

Wasn't sure what the real issue is so I figure general chat would do.

I'm on MS1

Sequential module fell out?

Never had sequential. It's running COP on waste spark.

Sequential injection, not ignition.

Sorry I misread. I don't have anything sequential... that I know of. I thought MS1 wasn't capable of that. I checked the wiring harness and all seems fine. I opened MS and didn't see anything out of place.

I inspected the injector to make sure that they were not firing. I switched 1 with 2 and 3 with 4 to check if they were stuck and they are not. All for injector can squirt. I then checked the voltage at the harness and all 4 clips showed 12v with the ignition on. Then I cleaned the grounds under the brake booster and #2 and #4 still won't fire.

Is MS not grounding the injectors? or am I missing something?

Sounds like driver #2 that drives injectors 2 and 4 has gone belly up.

So I just discovered the harness has a cable that came apart from the pin.

I've looked for the harness diagrams but it seems that the site hosting the images is no longer up and couldn't find anything that could guide me.

I looks like it belongs to this pin (there seems to be some solder residue)

Do you have a wiring diagram?

The MS was build by Braineack right? I can see if I can dig up a wiring diagram when I get some time, honestly don't know when that will be though.

So I managed to dig this diagram out. If this is correct, then the blue wire that came off the pin is the for the injector bank.

Frank's site has a picture at the bottom that might also help.
