the ignition module has been replaced ran for about 9 miles and cut off going down the road.
Expert:  JHoop replied 5 years ago.
Follow that chart I provided. You may have to replace the pick up coil in the distributor or you have a bad ECM
Customer: replied 5 years ago.
can the pick up coil make the fuel injectors not work?
Expert:  JHoop replied 5 years ago.
Yes and you will have no spark too.
