I replaced Injectors 4 & 8 after having them Diagnosed at a Ford dealership. This was my 3rd trip into this area (2nd on the right bank) as I have been replacing them as they go out. What I found odd was that one of the ones reading weak was one I had recently replaced. When I removed it, it was still like new more or less looking like I had done the job yesterday. I went ahead with the change out. Once done, when it started up ran on 7 cylinders. I shut it off, checked the plugs and fired it back up. Only 7 were kicking so shut it down. I checked the ScanGauge-X and it showed P0283 DTC meaning #8 High Current current. That says a short in the harness or a faulty solenoid in the injector. I went over the wiring real well seeing no chaffing. I pulled the FICM looking for bent pins with all good connections.
I will do a voltage check on the FICM in the morning, but I highly doubt thats the issue here.
Could the Injector itself be bad? Could there be another issue Im not getting. Is it a viable test to plug in one of the core injectors outside of the motor to see if I get a different reading?
I just dont see how I suddenly have a harness issue.
I have not run the truck other than twice to hear the miss. Maybe a minute total.
