Won't start after misfire and white smoke

2019 grand cherokee 3.6l won't turn over. Yesterday the 22nd, that morning attempted to start car, made grinding sound. Second attempt started with cloud of white smoke from exhaust (no smell/not head gasket). Got to work, put scanner on it, cylinder 4 misfire. After work, car wouldn't start, only a slight knocking noise from right side of engine. Swapped coils, no change. Inspected harness and checked for power (don't have voltage reading at this time). Oil was full, slightly burnt smell. Checked fuses and relays, no change. After work today, new noise from fuel pump. Also tapped starter with hammer to see if it would start, again no change. Was not able to jump starter due to its position!

Side note: replaced all 6 spark plugs, disconnected battery for 24 hours, misfire code went inactive, but Manifold Absolute Pressure Sensor became active.

This beast saved my life, the least I can do is return the favor! Please help.
