IMO: It's somewhat difficult to interpret, your description of the problem, "ie" ( "when it did it didn’t quite seem like it cranked over to the right spot where cars normally crank over to." ) It would be most helpful, if you could post a short video, showing exactly, what the issue is. Not sure, about your car, but routinely, it is not a good idea, to pump the gas pedal, in fuel injected cars. Pumping the gas pedal, MAY have introduced, too much fuel, into the system, causing the engine to misfire, resulting in the " jerking", and potentially, trigering the check engine light. Also, extremely hot weather, is very hard on batteries. You may want to take your car to the nearest auto parts store, and ask them to test the battery, starter, and alternator, for proper performance. Most large chain stores, will perform these type tests, at no charge.
