Good evening, all,
I've replaced both the CCRM and fuel pump motor in my son's '02 coupe, but now have the underhood fuel pump fuse (F1.14) blowing every time I move the key to the on/run position (before pushing it forward to start).
I alternated disconnecting first the CCRM then the pump, trying the key after each, and the fuse pops only when the pump is connected (C463 connector behind the bumper). With a good fuse installed, though, I get continuity on the harness-side of C463.
When only the CCRM is connected, I hear the integrated FP relay click when the key is engaged, which leads me to think it's okay. I also, though, sent 12v through pins 6 & 7 of the tank-side C463 connector and heard the new pump run fine.
Am I right in assuming the pump shouldn't run if the short was in the pump itself or tank-side connection? I lowered the tank to ensure the tank harness wan't binding on anything, with no luck. Again, though, it runs fine and indefinitely with power applied to connector.
Any suggestions for chasing this apparent short would be greatly appreciated.
Thanks,
Ramon
