How do you set the timing on a 1985 4-cylinder GMC truck with a 4.3 liter engine?
[Edit]

Answer

first off a 4.3 liter is not a 4 cylinder it is a 6. however if you need to set the base timing,you will need to disconect the base timing wire from the computer underneith the dash,(if it is computer controlled) it will be a brown wire or a brown wire with a white stripe. Goto the library for more information on which wire to disconnect. next loosen the distributor bolt and connect a timing light to number one plug wire. Start the vehicle and point the light at the cranshaft pully and rotate the distributor to correct the base timing according to factory specs, which will show up as a scribed line on the crankshaft pully. the single most important thing is to get a book from the library and watchout for the cooling fan while the engine is running (be carefull!!!)
