Hello and welcome to Just Answer

its possible that you have a stuck injector?

I'd say to turn the ignition on and off a few times to run the fuel pump and then remove a spark plug to see if its wet

as there should be no fuel injected if the engine isn't turning

if the plug is wet then you will need to replace or clean the injector

if thats OK then its possible its due to a faulty water temp sensor. If this is the problem then the ECU will be leaving the car constantly ' on choke' and not reducing the fuelling as the engine warms - so unplug the sensor and clean the contacts on both sides with some switch / electrical cleaner (not WD40) and inspect the wiring for any signs of damage to the insulation especially where it runs over other components and through the bulkhead- if this doesn't help consider replacing the sensor as they're not expensive
