Voltage drop testing will show power or ground circuit problem .

Also looking at a wiring diagram to see which ground point distributor is attached too. Free wiring diagram here http://www.bbbind.com/free-tsb/ Enter vehicle info. Year , make , model etc.... Under system click on engine , then under subsystem click on fuel controls . Click the search button then the blue link . Looking at the diagram ,i don't a ground for the distributor . Battery voltage supply to the coil , ground side goes to the ICM - ignition control module . You pulled the coil wire to the distributor an checked for spark ? No spark , ICM or crank sensor could be the problem.

2004 chrysler van 3.8 motor replaced coil pack still doesnt fire number 4 cylinder


If the coil pack has a four wire connector, one wire is primary voltage, the other three wires are ground, one ground for each coil, one coil fires two spark plugs. If problem with coil or ground, you would lose spark for two spark plugs. Did you visually check for spark, everywhere? What about the spark plug wire or the spark plug, itself?

I just replaced my coil pack 93 astro. Drive it 2 miles it backfired and died now coil is no good. Got another one same thing


are you sure the coil is bad and not a problem with the module in the distributor,you could try unplugging the tan wire with black stripe, connector near distributor and see if it starts, in 26 years ive seen alot more module failures than coil failures.

My car shuts off and stalls sometimes when i am


Could be fuel filter, fuel pump, air filter, coil, spark plugs, plugged catalitic converter, injectors or a host of other things. Start with the simple things like air filter, see if its dirty, then fuel filter especially if it has not been changed for many miles. Check battery connections, ground wires from body to motor and ground wire from battery to motor and body
