Question about Chevrolet Silverado 1500
There isn\'t one. The vortec engines did away with timing light based ignition timing. The distributor can be adjusted, but it adjusts something called Camshaft Retard Offset, and can only be checked using a scan tool. The ONLY reason you would need to check that is if you have recently replaced the intake manifold or removed the distributor from the engine, or have reason to believe that the distributor is off a tooth or two.

Look under the hood on the fire wall behind the engine there is a black cover with 3 tall black what look like nuts. remove them and you will see a relay center, now there should be a brown wire marked timing may be not marked but pretty sure its brown just unplug it and go from there. I sure hopes that gets you going and thanks for using

That was a good suggestion by Molson. Also, if you have been doing a lot of heavy hauling, have them check the strainer, which could be a problem as well.
