Does it crank?  You didn’t say.  Spin faster!

Enough humor.  If it turns over with or without a jump, it’s not the starter.
Backfiring in the exhaust is a sign that it could be loading up with gas
(bad injector, vacuum leak, loose tubing to the air inlet), or ignition
problems (bad points, wobbling distributor shaft due to wear, basic tune-up).
Check for vacuum leaks with some carb cleaner.  Spray extra fuel into inlet,
RECONNECT ALL AIR INLET TUBING, then try to start.  If it starts and runs,
cutting out a few minutes later, check the injectors including the cold-start.

ease off the gas.  don’t lift off abruptly.
if you do this in a 911 at speed, you will find yourself facing backwards
in very short order.  the traction control in the ’92 corvette that i
was driving did this to me by cutting the gas abruptly in a corner.
the tail, which had been gently drifting, abruptly slid out, requiring
lots of opposite lock to keep the car from spinning.

With a rear drive car, like yours, the trick is to let off the gas until you
feel the rear tyres gain traction.

With FWD you can generally ignore the situation. If the front tyres have
grip you can rest assured that the rear end will be along shortly.
