Alarm system

You can't "cut" the factory anti-theft system. When it is activated, the engine will run for only two seconds, then stall. It sounds like you have a charging system problem. Jump-starting is the clue. That won't overcome any anti-theft system. If you charge the battery at a slow rate for over an hour, you'll find the van runs a lot longer.

Start by using an inexpensive digital voltmeter to measure the battery voltage while the engine is running. It must be between 13.75 and 14.75 volts. If it is low, measure the two voltages on the two small nuts or the two small wires plugged into the back of the alternator. Those must be measured with the engine running. Holler back with those numbers.

Dealer for re programming but if you normally buy anew one there they reprogramm all of them at asame time
