My son just inherited an old jeep cj5 from his uncle. its been in the fam a while. its 1975 cj5. I bought new cap and rotor but still no spark to plugs. Does anyone know what i need to do to start it? seems to get a spark to center of the cap but its not quite 12 vdc.

 

has the coil been changed

 

Try the camshaft positioning sensor. In the distributor. Its called the pickup sensor in some circles.

by the way.. This post belongs in the OEM Tech Section.

 

I have replced the pick up coil, the coil, the rotor and cap. weird still no spark.

 

make sure coil has a good ground run it to the batt to test it. might wanna check the main and body to engine grounds

 

voltage to center of the cap should be in the thousands as in light yo azz up voltage


later year but it might help
