Re: Gmc v6 ignition problem
Replace the points and condenser. Set the dwell to spec.

Re: Gmc v6 ignition problem
There should be a ballast resistor wire that limits the voltage to about 9 volts. 12v into the coil damages the condenser and points. If there is still no spark after all parts are replaced correctly then the distributor is internally grounding somehow. Then you swap out the distributor for another. You need to get a service manual that guides you through trouble shoots. Or do more research online. There is another site you can also post for help.

Re: Gmc v6 ignition problem
this is before the coil correct and if this is damaged I wouldn't get any power to my coil?

Re: Gmc v6 ignition problem
Make sure the points are adjusted correctly. Around .017", I believe?

Re: Gmc v6 ignition problem
Standard troubleshooting procedure:
Take off the distributor cap so you can see the points. Turn on the ignition switch and rotate the engine by hand until the points are open. Now use a multimeter or test lamp to check for power at both the (+) and (-) terminals of the coil. If no power on either one, you have a break somewhere between the coil and the switch. Work backward toward the switch, checking at each point where there is a terminal or connection until you find the break. If you have power at (+) but not at (-), disconnect the lead going to the distributor. If you have power at (-) now, you have a short to ground somewhere in the distributor or the connecting wire. If you still have no power at (-) with the lead disconnected, you have an open coil primary, but this is VERY rare. If power at both (+) and (-), turn the engine by hand until the points are closed. Now you want to see power at (+), but not at (-). If you still see power at both terminals, you have a break between the coil and the distributor, or else the points aren't making contact. |

Re: Gmc v6 ignition problem
For about $75.00 you can change out all the internal components with Petronix Electronic Ignition, I did mine 6 years back and have not had any problems with it.
