Oil light will not start

Old battery have to get jumps often.

Sitting parked in idle and the car was fine but then began to shake and as it shook the oil light flickered and then shook rougher and turned off and the oil light came on solid.

Put gas in, not that.

Hooked to friends Prius did not start.

Cranks but does not fire.

There is a coolant leak coming out of the little screw cap right of the engine, and was barely visible but still present white smoke from tail but it went away.

Car cranks quickly but does not fire, all lights work, convertible top works.

Used one, nothing no check engine light.

Plenty of fuel.

The coolant is septic and probably needs changing, the oil is dirty and sticking my finger into the fill hole there is a lot of grudge and dirt on my finger.
