Expert:  Tim's Auto Repair replied 4 years ago.

ok

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

thanks

Customer: replied 4 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
Expert:  Tim's Auto Repair replied 4 years ago.

no

this 98 must have the crank sensor...no way around it..do check the icm..it can cause this also

thanks

Customer: replied 4 years ago.

Expert:  Tim's Auto Repair replied 4 years ago.
