RrrrRrrrRrrr means the starter is turning the engine over, it just can’t start. Maybe it’s not able to turn it over fast enough. Could be out of fuel, not getting enough fuel, not getting a sufficient spark, or the air flow to the engine is clogged. I don’t see an air clogging problem, so that’s probably not it. As a tow truck driver in my earlier life, I’d check the fuel gauge next. Then I’d try to jump it from a good battery. After that, I’d probably tow it in and let a mechanic in a nice warm garage check it out (although I’ve been known to adjust points on the side of the road to get a car going again).
