• bought from a sketchy small dealership 165k miles
• Changed transmission fluid(jet black, some glitter)
• spark plugs covered in soot
• valve gasket cover hard as a rock
• alternator and drive belt replaced
• still getting one click and hum when trying to push start the jeep
• cleaned the throttle body butterfly

So is it a bad ground strap, relay fuse? because no codes will show up except some old ones that say driver/passenger door module issue. if I hold the window up/down button my engine hums. they cut the wiper fluid tubes under my hood. I see that they ripped foam out to get to the low/high trim fuel line. Im out of answers. It will start after a few tries but engine light blinks when malfunctioning.
