If you're having fuel delivery problems, the issue is likely something more serious than a simple reset. Possible causes include:
* Bad fuel pump: This is the most common cause of fuel delivery problems.
* Fuel pump relay: This electrical component can fail and prevent the pump from operating.
* Clogged fuel filter: A dirty filter restricts fuel flow.
* Low fuel pressure: Various components in the fuel system can cause this.
* Wiring issues: A problem in the electrical system leading to the fuel pump.
You should consult a repair manual specific to your year and model van or take it to a qualified mechanic to diagnose and repair the fuel delivery problem. Trying to troubleshoot this without the proper knowledge could be dangerous.
