Re: 95 g30 no start

Are you saying it has no spark?

If so,

It sounds like heat could be causing the ignition module in the distributor to break down. Many auto parts stores in my area will test the distributor module for free if you bring it in.

The test results from these stores are not always accurate, and some times the will say the module is good when it is not, but for a free test that may find the problem it is worth a try.

Make sure when you install or reinstall the distributor module that you use heat sink compound under it. The compound helps dissipate heat from the module. Without it, the module will fail.

If it has spark see if it is injecting fuel when the engine is cranking.

The computer needs to receive a distributor reference pulse from the distributor module to trigger the injectors.

Re: 95 g30 no start

If the injectors are spraying fuel it tells you that the pick-up coil in the distributor is working and the module is sending a reference signal to the computer.

The distributor module could still be the problem.

You may want to try another coil wire. The center core of the coil wire on these trucks will burn so open that spark will not get through the wire anymore.

Re: 95 g30 no start

Everything is pointing to the distributor module as the problem part.

Also make sure the wire terminals in the connectors to the module are not stretched out.
