No amount of cranking the engine will start it. For this year/make/model it would probably be cheaper to either purchase another vehicle or swap in a low mileage engine than repair the current one.

The results are increased wear on valves and potentially melting the aluminum of the head. The melting is under extreme conditions. You are in a situation where ...
I would have the front wheels bearings checked. A bad bearing can cause sensor misalignment and the ABS to activate. You may also have an issue with the power brake booster.
