The problem is in the start circuit if the starter won't engage from the key. From battery to ignition switch to neutral park safety switch to starter relay to starter solenoid to starter to ground and back to battery-lights come on so switch is good, next check the neutral safety switch for power in and power out.
Once you get the start circuit working so starter engages from the key, then you can address the ignition circuit for possible no spark.

bottom rear of engine on the passenger side, the starter is serviced from under the car. it is held to the engine block with two bolts, then u must remove the battery cable and starter solenoid wiring as well, always disconnect the battery before doing any work on the starter.

2.2L Engine remove protective shields as needed then remove front exhaust pipe. Remove the brace from the engine to the clutch housing, then disconnect starter wiring. 4.3L Engine 2 wheel drive just remove the right front tire and you will have access to the wiring. 4.3L Engine 4 wheel drive you must remove the differential carrier shield if equipped then remove the starter bolts and rotate the starter to get access to the wiring. Good Luck.

SOURCE: 94 gmc sonoma 4.3l vortec new coil, plugs, wires

The ignition module in the distributor is what you need to give the engine spark to the plugs. It senses signals from the PCM to regulate the spark control and this item is the part that took over the old style point & condensor type ignitions. It is time for a new one in your truck
