Re: "Fast start" feature
Somewhere in the 89 timeframe they came out with it for the V6 engines. If yours had it, you should see something about it in the starting part of the owner's manual. The power pack advances the timing slightly when cold. Once the engine warms up, the power pack returns to "normal" timing. If you had a service manual, you may be able to determine how to disarm it. Or, just wait till the engine is warmed up to perform your timing procedure.
