no it has a timing chain.
There are a few ways to set the timing on a 1994 Suburban 1500. Disconnect the connector firewall to loosen the distributor turning just a bit clockwise.
Adjust your timing
YOU can if you have an engine scanner. if you have not fooled with the distributor then there is no need to adjust the timing because it is controlled by the ECM / computer. It will adjust it's self.
THE TIMING IS COMPUTER CONTROLLED. It requires an engine scanner to set the timing on that engine.
if it has a distributor you can.
The timing is controlled by the powertrain control module - not adjustable
That requires an OBDII engine scanner to do that. The ignition timing is controlled by the computor. If you have not moved are removed the distributor then there's no reason to fool with the timing.
Computer controlled If you have a 3.0 you can turn the distributor to adjust, after you pull out the adjustment chip.
