What is Ignition timing procedure for a 1992 Chevy s10 2.8L v6?
I know that you have to put the truck in base timing mode for my 93' but I have a EST or HEI style ignition. If you have the electronic distributor then find the grey wire with a plug on the end of it next to the A/C box on the left side under the hood near the firewall. It will be hanging out of the wire harness. Apply 12 volts to it from your battery with a jumper wire and the truck will go into base timing mode. then line up the marks on your balancer. take the jumper wire out and your set.
The full procedure is a bit lengthy to write out so I've attached some links below to show you how. To adjust your ignition timing loosen the 12mm bolt in the middle of the distributor slide and move the distributor towards the front of the truck to advance the timing, move it towards the back of the truck to retard the timing.
