1994 Voyager 3.8L swapped.

On my way to work this morning the van started running very rough, CEL came on.

I pulled the codes and got a code 27 (Injector control circuit does not respond, problem in circuits 3/4), and the code 32 (for the EGR which it's had for a while).

Until today this drivetrain has been working phenomenally. I don't want to drive it home for fear of wrecking something, but I don't really have a choice.

Hopefully someone has an idea where to start/what would cause this/etc.

Thanks in advance guys.

 

Checked connections at the injectors and going to the ECM, everything is good there. I don't see and broken/bare wires either.

 

Did some simple testing of unplugging injectors to find the one that wasn't firing. Number 6 injector was "dead". Tested to ensure it had power and was getting proper pulses, it was. Replaced it, problem solved.
