Answer 1

This is a test only forum, so we can't SHOW you what you want to know.
HOWEVER, with hood open, standing in front looking over radiator at the front of the engine, driver's side just about 2 o'clock above the harmonic balancer you will see the pointer, and the marks indicating "0" or TDC, 5 deg, 10 deg, etc. The index mark is on the balancer itself.
Be sure to read the instructions on the ( Vehicle Emissions Control Information (VECI) label for checking and adjusting the ignition base timing. Be sure to follow them exactly, as if you don't, your adjustment will not be within range.
Also be aware, that if there are any components for the computer that register out of range (i.e. throttle position sensor) you MAY see timing at something over 20 deg or more advanced.
If this is the case, It is important that you either follow proper diagnostic procedures, (repair manual) or take it to a shop for diagnosis and repair.
There is simply too much to know to try to just "wing it" where computer control is concerned.

Good Luck
