Also, the same night the car wouldnt start, my engine coolant was bone dry!

yes a coolant leak will cause a car from starting .If it overheats to a certain point the ecm should shut the fuel off so you dont blow up your engine.tell yuor mechanic to first chech for power and ground if both are present it could be your fuel if there is no power scan test the ecm to see if you have a faulty temp sensor good luck
