The only way I could tell on the stroke length is to compare to a new one. I don't have anything on that either. Doesn't offer anything on this car.
Your logic sounds good.
Are there any codes?
Using Voltmeter
The service codes can be interpreted using a voltmeter. These codes will appear as a fluctuation of the needle, indicating the first digit of the code, followed by a two second pause, then a second series of pulses indicating the second digit of the code. For example, a code 3-2 would be indicated by three pulses, a two second pause, then two more pulses. If more than one code is indicated, there will be a five second delay between codes.
Using STAR Tester
After connecting STAR tester, the tester will run a display check as follows: The numerals 88 will begin to flash in the display window, followed by a steady 00, which indicates that the tester is ready to start the Self Test and receive service codes.
To receive service codes, press the push button at the front of the tester. The button will latch downward and a colon will appear in the display window in front of the 00 numerals. The colon must be displayed to receive service codes. If the Lo-Bat indicator shows steadily during operation of tester, turn power switch Off and replace the unit's nine volt battery
