Number 4 fuel injector not functioning
This is a puzzler. My # 4 fuel injector is not working. I replaced the injector and it did nothing. The lead to the injector has 12.6 volts and the one I removed will funtion when I attach it to the other leads (1, 2, 3). When I try to pull codes from the ECU, the Check Engine Light just stays lit.
Please help before I rip my hair out.
Thanks

What makes you think it's the injector? Because the cylider isn't firing? Could also be the spark plug or plug wire. Have you checked for spark?

Re: Number 4 fuel injector not functioning (nub)
That was the first thing I checked. Spark is fine. The other three injectors are clicking when I listen with a screw driver. I am at a loss.
