It threw white smoke from exhaust And turned off and it won’t Start again

What is your question?

The engine light came on it showed a misfire so I change 5 spark plugs and a coil and it still continue To bring the check engine light it would turn on and erase And come back on and this afternoon I just all the fluids oil was good level and by the way I recently did an oil change so oil is clean and good and I checked the anti freeze it was very low not to empty but low so I drove to my local Walmart bought engine coolent and filled it to the top and squeeze the big pipe it runs so it can suck in to the radiator And drove to another store to buy important stuff and when I try to start it it took like 4 seconds to start until it finally started and then I drove back to my home and as soon as I wasn’t parking I decided To give it a little rev to check if everything is good and it completely Threw white smoke from exhaust For 5 seconds and it turned off at the same time and now it won’t turn back on the battery is still good
