Chevrolet Repair: cranksensor, crank sensor, scan tool

Question
My chevrolet cabalier 1993 wont start how do I know if the crank sensor is
bad.

Answer
HI LUIS, THE BEST WAY TO TELL IF THE CRANK SENSOR IS BAD IS GET A SCAN TOOL AND GET INTO THE DATA SIDE OF IT WHILE CRANKING THE ENG OVER AND SEE IF THERE IS A CRANK SIGNAL..IF THERE IS THE CRANK SIGNAL THE SENSOR IS OK..I HAVE SEEN MAY PROBLEMS WITH BAD IGNTION MODULES AND CRANK SENSORS.. WOULD SUGGEST REPLACING BOTH OF THEM AT THE SAME TIME IF YOU FIND IT IS THE CRANK SENSOR OR MODULE.. SEE IF YOU CAN RENT A SCAN TOOL FROM A PARTS STORE. USUALLY YOU CAN..REMEMBER THAT THIS CAR IS PRE OD11...GOOD LUCK AND LET ME KNOW HOW IT GOES...TOM
