My Talon is currently running on three cylinders. The #2 injector is not firing. I believe that my ecm might be bad but I thought I would post this before I ordered one as I am not a fan of swapping parts for fun.

All injectors have ~11 volts when the key is in the "on" position.
All injector ground wires have continuity to the ecm plug.
I replaced the non working injector with a remaned one.
I have noid-light tested the injectors and #2 doesn't light up.


The ecm is remanufactured and does not have any burn marks, just some yellow looking stuff on the board around the capacitors.

I believe that I have checked everything that I could check for this problem. Can a bad ECM cause one injector to not work?
 
Hopefully these pictures are good enough.

I replaced the ECU and it runs perfectly. Apparently not all remanufactured ecu's are of great quality.
