Over time, the fuel injection wiring harness can be damaged and needs to be replaced. If you notice your vehicle is idling roughly or misfiring or your engine isn't performing normally, be ...Problems with fuel injector circuit. This is my first time posting. I bought a 2009 cadillac cts 3.6 and it will not run. Whwn it does crank it runs really rough. So i read codes and looked at live data when it did crank and it showed injector 6,3, and 4 is not being commanded on the codes are p2152, p2155, p216d.This code sets when the powertrain control module (PCM) detects a signal from the injector or its wiring that doesn’t meet the expected values. The “Cylinder 6” in this code’s definition means that the problem is possibly connected to the fuel injector in the engine’s cylinder number six.Re: Injector wiring, power/ground help! (invain) Well, we fixed the voltage problem, there was a short in the power wire for that injector and the connection back in the harness was pretty ****ty too. 12 volts at the injector plug now, but it's still not firing. We've checked continuity for the ground wire back to the ecu for that cylinder and ...If fault follows the fuel injector(s) swap: Replace the affected fuel injector(s) only. If the fault remains on the original cylinder: Perform a temporary overlay from the ECM to the fuel injector and retest. If the fault no longer returns after an extended test drive: Replace the engine wiring harness and the 8 pin injector harness.OK, the computer grounds one of the curciuts on each injector to pulse it. Interesting information from alldata, the autodata and mitchell and Bosch AFC all show a code 11 as being ECM (B+) that I have, which could be the EFI main relay, fuse, fuse link or wiring (usually one of the wires on the battery terminal have broken off or corroded and lost connection)The fuel injection wiring harness provides power to the injectors and the oxygen sensor, which determines how much fuel is needed for maximum efficiency. Over time, the fuel injection wiring harness can be damaged and needs to be replaced. If you notice your vehicle is idling roughly or misfiring or your engine isn't performing normally, be ...I'm thinking either a ground short at/in the connectors, a short in the wiring from rubbing, or the common 2/7 injector connector faults Its kicking these codes, which make me think a wiring short as well: P0202 - Inj circuit / Open Cylinder 2 P0203 - Inj circuit / Open Cylinder 3 P0205 - Inj circuit / Open Cylinder 5 P0208 - Inj circuit / Open ...4045 (4.5L and 6.8L Level 11 Electronic Fuel System with Denso HPCR) 4045 (6.8L - Level 4 Electronic Fuel System with Bosch VP44 Injection Pump) 4045 (Level 34) 4045 (PowerTech Final Tier 4-Stage IV) 4045 (PowerTech Interim Tier4-Stage III B 6068 (PowerTech Interim Tier 4-Stage III B (174hp) 6090 PowerTech (Final Tier IV – Stage IV).
