SCAN IT CHECK COOLANT SENSOR IT WILL CAUSES STARTING PROBLEMS IF ITS NOT WORKING.DOING COOL ENGINE START UP COOLING SENSOR MONITOR COOLANT TEMPERATURE SENSOR.IT WILL ENRICHEN FUEL MIXTURE JUST FOR COLD STARTING ENGINE.IT WORK LIKE SAME PRINCIPAL LIKE A CHOKE ON CARBURETER ENGINE.WHEN ENGINE WARMS UP THE COOLANT SENSOR AND OXYGEN SENSOR WILL LEAN OUT FUEL SYSTEM .WHICH IS CLOSED LOOP.CHOKE ON CARBURETER WILL OPEN AUTOMATICALLY AS THE THERMOSTATIC METAL COIL WARMS UP.YOU NEED A RICH FUEL MIXTURE WHEN COLD STARTING ENGINE.NOW A CLOGGED AIR FILTER BAD PLUGS + WIRES CAUSE WEAK SPARK NO START UP.SO I WOULD HAVE A GARAGE OR SOME BODY WITH A SCANNER SCAN IT TO SEE WHAT THE PROBLEM IS.YOU WONT SPEND TOO MUCH MONEY GUESSING.
