I have tested my coil pack, replaced my wires & plugs & still get this set of codes. I think its the fuel injector. How do I check it. Its a 03 Ranger 3.0 flex fuel. I have a multi gauge. What should the injector read.
thanks

 

Not exactly sure, but it should ohm out real close to the rest of them. You will need a noid light to check the injector pulse at the connector from the PCM.

 

I found it on a different site. Its 12 to 15 ohms. I made a light to test the pigtail
