Here's a breakdown of likely causes and what to do:
* Weak or Corroded Battery Connections: This is the most common cause. Corrosion on the battery terminals (positive (+) and negative (-)) prevents a good electrical connection. Clean the terminals thoroughly with a wire brush and baking soda solution, ensuring a tight connection.
* Faulty Battery Cables: The cables connecting the battery to the starter and the rest of the electrical system could be damaged, corroded, or loose. Inspect them carefully for any breaks, fraying, or corrosion. Replace any damaged cables.
* Faulty Starter Solenoid: The solenoid is an electromagnet that engages the starter motor. A faulty solenoid may not be receiving power or may be internally damaged. This often manifests as clicking noises when you turn the key.
* Faulty Starter Motor: The starter motor itself might be worn out or damaged. This requires professional diagnosis and likely replacement.
* Loose or Corroded Connections at the Starter: Check the connections directly on the starter motor itself for corrosion or looseness.
* Ignition Switch Problem: A faulty ignition switch might not be sending the necessary power to the starter solenoid.
* Wiring Problems: There might be a break or short in the wiring between the battery, ignition switch, and starter. This requires tracing the wiring to find the fault.
What you should do:
1. Safety First: Don't attempt to jump-start the vehicle until you've investigated the problem. Improper jump-starting can cause damage or injury.
2. Visual Inspection: Carefully examine the battery terminals, battery cables, and starter motor connections for any signs of corrosion, damage, or looseness.
3. Check Battery Voltage: Use a multimeter to check the battery voltage. It should be around 12.6 volts when fully charged. A low voltage indicates a weak or dead battery.
4. Seek Professional Help: If you're not comfortable working with car electrical systems, take your van to a qualified mechanic or auto electrician. Trying to fix this yourself without the proper knowledge and tools could lead to further damage or injury. The screwdriver method is a dangerous workaround and shouldn't be repeated.
Ignoring this problem could lead to being stranded and potential for more serious and costly repairs down the line. Get it checked out as soon as possible.
