Is there a kill switch on a 2000 Plymouth Grand Voyager?

I recently had to replace the timing cover / water pump mount / compressor mount bracket on my van. After this was done, the car would not start. I thought at first it was just low on gas, but after adding gallons of fuel, it still will not turn over. It will crank, but there is no attempt by the engine to actually start. Is it possible that there a 'kill switch' that shuts off the fuel pump, like in the event of an crash to prevent explosion of the gas tank? If so, where would I find it so I can turn it back on?
