Sounds like your "traction control" system is having issues such as a wheel speed sensor. You can have these type things scanned free at your local auto parts store, Auto Zone, Advance Auto Parts etc. etc. They should be able to "steer" you in the right direction. Hope you get the problem at hand resolved, for that is dangerous driving like that. Jesus loves you, John 3:16-17 (KJV)

Battery Disconnect or Replacement Problems

Were is the radio ground wire located on my 05 avalanche? Radio goes in and out all the time.

It should be on side of transmission.

Has no fuel switch . Filling the vehicle with fuel would not have anything to do with it a day later . Is it fuel or ignition system problem ? Testing would need to be done to find which > Sounds like your best bet would be to have A qualified repair shop check it out .

That's odd - I am not aware of any configuration change that can be made to the radio that could change the operation of this switch. So, I think the problem may be internal to the radio (not interpreting the input of this switch correctly). You could try resetting the radio (and all other modules) by carefully removing the negative battery cable for a few minutes.

Are you stepping on the gas pedal while starting? If so don't fuel injected engines do not need priming.

Can only help by putting in a new oil pump as well. I would say remove the heads and check where the coolant is coming from. Bad head or crack in a cylinder wall.
