I have a 1991 honda accord. I was driving down a busy road when the car began jerking off and on then cut off. When I attempted to start it again, it turned but did not start. What could be the cause of this?

Perform the tests outlined in Sections A and B below:

Have your Igntion Control Module (ICM) and coil tested for free at AutoZone. I suspect the ICM may be bad. Also, make sure to replace the fuel filter, which could cause your symptoms.
