Therefore, there's no switch to simply reset. If you suspect a problem with fuel delivery, the issue isn't likely a simple switch. Here's a breakdown of potential problems and how to address them:
* Inertia Switch (Crash Switch): This is the most likely candidate if you suspect a fuel-related issue after an accident or a sudden stop. This switch is designed to cut power to the fuel pump in a collision to prevent fires.
* Location: The inertia switch is typically located under the dash or in the engine compartment (consult your owner's manual for the exact location on your specific year and model). It usually has a small red button that you can push to reset it. If you push it and it clicks, then it's reset. If the button doesn't click or it won't restart, the switch itself might be faulty and require replacement.
* Fuel Pump Relay: A faulty relay can prevent the fuel pump from receiving power. You'll need to consult a wiring diagram or your owner's manual to locate the fuel pump relay and potentially replace it.
* PCM Issues: The Powertrain Control Module controls many aspects of the vehicle, including the fuel pump. If there's a problem with the PCM, it can prevent the fuel pump from operating. This requires professional diagnostics and likely repair or replacement of the PCM.
* Low Fuel Pressure: This could be due to a clogged fuel filter, a faulty fuel pump itself, or other problems within the fuel system. A professional mechanic will need to diagnose this.
* Other Electrical Problems: Issues with fuses, wiring harnesses, or other electrical components can also prevent the fuel pump from working.
In short: Check your inertia switch first. If that's not the problem, you need professional help to diagnose and repair a fuel delivery problem. Attempting to troubleshoot advanced fuel system issues without the proper knowledge and tools is dangerous and can lead to further damage or injury. Take your van to a qualified mechanic or dealership for diagnosis and repair.
