Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hi There, This is Clay, I'm a certified master automobile technician with 30 years of automotive repair and diagnostic experience.
From your description I'd say there is a wiring problem to the injectors. The DG/BK wire is power from the ASD relay to the PCM, coil positive and to both of the injectors. There should be power during cranking. At the injectors, the WT/DB and the Tan should pulse ground with a test light clipped to the battery positive. I understand that one of the injectors works properly. Check the other and let me know if there is power missing or the pulse to ground.
If there is no pulse to ground check the injector's circuit at pin #16 for injector #1 WT/DB and pin #15 injector #2 Tan at the PCM. If there is injector pulse at the PCM and not at the injector simply run a new wire to the injector from the PCM.
I hope this information is helpful. If you have any questions let me know. Also if you need a connector view with the injector pin locations let me know. You can reply back to me through this thread at any time.
Let me knowThanks
Thanks for getting back to me. It's not voltage you're looking for at the PCM. You need a ground pulse from the PCM to turn the ground on and off at the injector.
With a TEST LIGHT clipped to battery positive probe pins 15 & 16 at the PCM. With the engine spinning over or running. Does the test light flash on and off on?
This is the proper way to check or injector pulse.
This is with the PCM connector plugged in and checking the wires at WT/DB pin 16 and Tan for pin 15 for injector pulse.
The DG/BK wires at the injectors should have constant battery voltage during cranking and engine running.
Hope this helps, let me know.Thanks
