I originally posted this to an existing fuel door issue thread before I realized it was on the SRT6 page, so sorry for the duplication.
After arriving at work the other day I pressed the key fob to lock the doors and nothing happened. Thought maybe the fob had dead batteries, not the case as I walked around to the back of the car hit the fob and the lights flashed. So I manually locked the doors but this does not lock the trunk. This morning I took off the right rear trunk panel and the Styrofoam insert on the floor deck to expose the air pump, started the car and tried to listen for an air leak...nothing I could hear with the exhaust blowing on my legs. I then lowered the windows, car still running, and hit the manual lock button on the center stack, doors and trunk lock but the I am able to open the fuel door when everything else locks. The service manual is a little vague on the fuel door operation other than describing how to remove the locking part near the gas cap to then pull out the lock actuator. Before I attempt this has anyone else experienced this issue of the fuel door not locking. I am assuming because of this issue that is why I can not lock the car? Any assistance would be most appreciated.
Thanks,
PJ
If all of this is factual and you have not become confused in your description of symptoms, I'd say you have two issues:
1) The key fob you are using needs new batteries or complete replacement.
2) The pump has a real problem. (You mention the trunk didnt lock when it should have and the fuel door lock is not working.)
I while you may have a leaky hose to the fuel door, you may also have a problem with the pump. Just keep in mind that you can suck or blow into the individual hoses and manually lock/unlock each lock. If you can't lock/unlock any one location, look for sluggish mechanism at the lock end or a leaky hose.
One more note - I do not understand why you started the engine to troubleshoot the pump. The engine running has nothing to do with this. The pump does two things: 1) It creates pressure. 2) It creates vacuum. (One is for locking, one for unlocking - but I cant remember which is which.)
