Timing is set by the PCM and is not adjustable.
Timing is set by the PCM and is not adjustable.
On the Vortec the computer does it all.
That requires an OBD2 engine scanner to set the timing.
set to zero degrees base timingthe computer controls actual timing
There is no ajustment for the timing on vortec engines the computor does it automaticly
There is no timing adjustment on that year. Computer controls the timing. This is partially correct. The distributor can and has to be adjusted to set the cam retard offset. For this you will need a scan tool that does this.
It requires an engine scanner to set the timing on that year engine.
NO there is not. The timing on that engine is computer controlled and it REQUIRES an engine scanner to set the timing. A timing light will not work.
The only thing you can do is set the basic timing by ear good enough to get it running If you just put the distributor in the engine. The timing is not ajustable it is controled by the computor. It requires an engine scanner to set the timing, not a timing light.
Probably computer controlled and not adjustable
If it is a vortec engine, then there is no timing ajustment. It's controlled by the computer
