88 Olds Delta 88

Hello there,
Im working on a 88 Olds Delta 88 3.8. The bendix in the starter went bad, I unhooked the battery cable and removed, fixed, installed the starter. I hooked the battery back up and now the car turns over but will not start. It has no spark at the coil pack. I can hear the fuel pump, dash lamps are working. One thing I noticed was that I removed the negative battery cable first, and I can remember reading 'take off the positive always' Could it be that it burned sumthin up?Ill bet I fried the PCM right?

Thanks in advance, Mike.
