I have a 97 GMC Sierra. I just replaced the oil pan gasket and now it won't start. I pulled a spark plug and I'm not getting a spark. I tested the crankshaft timing sensor and only got .7 volts. Not sure where to find the PCM. Haynes Repair manual has nothing on it.

Check to make sure the Crank sensor wiring wasn't pinched or damaged while doing the work.
