Need some help. Auto Xray has told me this:
Took some info on my Autoxray and noticed my fuel pump voltage is 13.3 and my battery voltage is 13.4. Usually the voltage is : battery=14.3 fuel pump=14.2
What would cause the voltage drop? Could it be the battery? The voltmeter is reading slightly lower and it looked like FP dropped a little on my gauge as well. I can also hear that the pitch of the fuel pump has changed
And while viewing "real time" mode on my Autoxray, I noticed Closed loop/ Open loop mode switches back and forth. Again, it never did this before either.
The oxygen sensor is new and is performing correctly. Any help or suggestions would be appreciated.
Thanks
