You need to be sure that the wiring is right before you just throw parts at it..

So...

code 15 is ignition output signal/ignition control module in the dizzy

code 16 is saying an injector is bad, or not firing right..

My advice is to check the wires from the ECU to both the dizzy, and to the injectors.. It's a total of like 10 wires!
Get a wiring diagram, and check for continuity on each.. If your checks are good, then check the parts!!

You have to ohm the injectors, and also check ignitor in the dizzy.


I say this because you said the car had a wire tuck at some point..
