96 GMC Jimmy Starting problems?

Just bought the truck a week ago, and its always cranked over very slowly. Today I parked it at a gas station came out and it turned over very slow and wouldnt start, I swapped out the battery and it fired right up. I drove it home and now its not starting again, not clicking, no sound whatsoever. Im thinking possibly a bad ground somewhere? Any input is much appreciated.

Changed fuel pump, cleaned fuel filter and other filters, no effect? Any suggestions? Or is there a specific way to drive when going uphill?

Sometimes loses power while driving on flat surface
+ onboard software is not being recognized when trying to connect.?

a '14, under Honda factory warranty, so at least call H dealers service dept. have cars VIN, Vehicle ID Number handy: on registration.

and instead of 3A, add road service on insurance, much more economical.

you could check battery cables & see if they'r loose, disconned, etc. buzzing is usually solenoid not getting enough electricity.

dont mess up warranty, have Honda take care of this.

Power loss, unbalanced load, could be lots of things.

My wife's washer shuts down if you open the lid. The lid hits the timer knob, shutting down power.
