WHEN I GOT BACK HE SAID MY RADIATOR WAS LEAKING BUT THE CAR WASNT OVER HEATING SO HE KEEP DRIVING IT..SO WHEN I GOT BACK AND DROP TO THE GAS STATION WHILE ON MY WAY BACK THE RPM HAND WAS VERY LOW ALMOST BY THE 0 WHILE THE CAR WAS RUNIN AND JUST OUT OF NO WHERE IT CUT OFF STARTED IT UP AND IT CUT BACK OFF AND DIDNT START UP.BUT NOW WHEN THE KEY IS TURNED AND THE ON POST THE OIL LIGHT STAY ON CAN ANYONE HELP TELL ME SOMETHING AND FAST

 

If the car is not running with the key on the oil light should be on since you have zero oil pressure.

You say the car won't start...does it turn over when you hit the key?
