Truck Want Fire

1. Battery Check: Ensure that the battery has sufficient charge. Check the battery connections to make sure they are clean and tight. If the battery is low or the connections are loose or corroded, it can cause starting issues.
2. Starter Motor: Check the starter motor for any signs of malfunction. Listen for any clicking sounds when you turn the key to the start position. If you hear a clicking sound, it could indicate a faulty starter motor or a weak connection. Consider having the starter motor tested or inspected by a professional.
3. Ignition Switch: The ignition switch could be faulty and not sending the signal to engage the starter motor. Try turning the key while gently wiggling it to see if the truck starts. If it does, it could indicate a problem with the ignition switch, and it may need to be replaced.
4. Clutch Safety Switch: Since you mentioned that there is no power to the clutch pedal switch, it's possible that the clutch safety switch or its wiring is faulty. Check the wiring and connections leading to the clutch pedal switch for any damage or loose connections. Consider testing the clutch safety switch or replacing it if necessary.
5. Neutral Safety Switch: In some vehicles, there is a neutral safety switch that prevents the engine from starting unless the transmission is in neutral or park. If your Sonoma has this switch, make sure it's functioning correctly. Try moving the gear selector to neutral and see if the truck starts.
6. Anti-Theft System: Some vehicles have anti-theft systems that can prevent the engine from starting. Check if your Sonoma has an active anti-theft system and ensure that you are using the correct key or try using a spare key if available.

If none of these steps resolve the issue, it might be best to consult with a qualified mechanic or GMC dealership. They will have the specific knowledge and diagnostic equipment to identify and resolve the problem with your truck.
