set the timing on a 1995 chevy truck?

With a timing light....

O.K., all kidding aside, to set the timing you must unplug the set timing connector, which is a single Tan wire with a black stripe/tracer on it. On some years the set timing wire is tan with a white stripe/tracer.

On your 95, I'm thinking it's located under the glove box inside the cab. Should be a single wire with a connector. Unplug, then set your base timing to "0", then plug wire back in. This will probably set a code you will need to clear out. Hope this helps.

R.R., do you have a service manual like a Chilton or Haynes? It details exactly how to do it.

I can get the manual from a friend, thanks for the replies I will try it this afternoon.

Ok I set the timing as the book said. It still backfires when driving. and gets where it will not run at all. Any suggestion!

What all did you do to it before you decided to mess with the timing?

Do you have any plug wires messed up?

Had to pull the distributor to install a pickup coil. It runs fine until it gets to normal operating temperature.

Where should the timing mark be after setting to "0" and the wire plugged back in?

Unplug the wire set it to 0 and plug it back in and the computer will do the rest.
