You didn't say what year, but judging by your Sig, a '92 ~'93 will have the PCM located behind the battery

- Be sure your crankshaft position sensor (at the harmonic damper) is about 0.050" from the damper and be sure it's plug (straight up, close to the radiator hose) is good and secure.

Crankshaft Position Sensor. Post #2 above.

Just spray it and surrounding engine with your favorite cleanser and hose it off.
