I have a 1990 Dodge Dynasty that will not start. It has a 3.3 v-6. Whenever I try to start it it will attempt to start but not catch. I have replaced the fuel pump fuel strainer and filter and still no start. On two seperate occasions the car has started normally and ran fine for a few days and then back to the no start issue. I am not sure what to look for next to get this car running. during my research I have come across information that points me in the direction of the crank sensor but I am not sure. Any help would be greatly appreciated.

It may be your crank sensor. You may also want to remove the coil packs and see if there is any corrosion under them, if there is this may cause weak ground clean the bottom of them with emery cloth and reinstall.

BTW welcome to the DF family!!!

 

would a weak ground on the coil pack (I only have the one coil pack on the 1990 3.3) cause the symptoms that I have with the no starts? Apart from the no start situation I have been very impressed with the driveability of this car.
