first time , pulled up to stop and while waiting for light , car died , started right back up , idle ran at 3500 rpm then droped off car then started running really rough and died , would not restart , smelled real strong of gas , discussed with jhoop , online when this happened , pulled codes , he told me to replace coolant sensor , i did so , car ran for a few months , took a drive to other side of mountian , then second time started , hello , doing same as before , with codes : 12 , 13 , 24 , 3 quick flashes , the wierd thing is the car today was running fine then again


i think you have a bad crank sensor..these will do this when they start going bad..this is located near the harmonic balancer...also remove the ignition control module[this is under the coils,take it to auto zone or most other auto parts stores,they can test the icm for free


Customer: replied 6 years ago.
is there a way to bypass the crank sensor to be sure that is what it is , carburated cars dont need this sensor to run , is there a way to disconnect it


this 98 must have the crank way around check the can cause this also


Customer: replied 6 years ago.
is the crank sensor basicly serve as the distributer

that and the icm work as the distributer...
