The first diagnostic, pulling the PCM connector and checking for voltage is easy. You can also visually inspect the white wire going to the C2 Blue connector, pin #35 and see if it's broken - if the car is a M6 maybe it's damaged from a shift light install or something? If you don't feel comfortable with the flow chart or suspect the IPC you might want to have someone look at it for you. Here's a description of all the PCM pins for the '98 - www.ls2.com/boggs/torques/98pinpcm.htm
