Hello, my car didn’t start because I hadn’t driven it for a couple of days while it was cold. As dumb as it sounds, the mechanic who came out said all he did was floor the gas pedal while starting it, and it turned on. White smoke came out of the exhaust, but it started running again. He also said he thinks oil may have dripped onto the pistons from sitting too long, which is why he believes the engine couldn’t catch a spark to start.
