Terry,
Thanks for the info. My codes reader says its "controlled ignition system or misfire"
It doesn't want to start cold and when it does it's an extremely rough idle.
If the engine heater has been on it starts with a normal crank, but trips the codes immediately. It was giving an injector circuit open code also untill I replaced the relay with the new one. Now it's just the misfire codes.
Can I and should I test power to the injectors?
