Ethanol content I’d wager . . .
I think this is the problem. BAD FUEL!
Last week a couples Lexus stopped in front of our business and wouldn’t start. They bought a fuel additive for water and put it in the gas tank. They let it set overnight....and bingo the car started the next morning an drove off. Sorry I didn’t get the name of the treatmentt any automotive parts store should know what it is.
Batches of bad fuel have been popping up quite regularly especially in California. Best of luck!
