See this FIG : Power, Ground, and Injectors(c) (2000), no data provided for 1999.
http://www.autozone.com/.../...rGuideContent.jsp

The powertrain control module sends a ground signal to fire the fuel injectors.
Local auto parts stores such as a Autozone or O'Reilly might have the fixture to test the PCM or you could loan it for a try.

This and the crankshaft position sensor is what I'm leaning to, thank you!
