How do I get my van to start

I put my van in a field that had water that reached the
middle of my door. I had it towed I let it set for it one day. I
have tried to get it started after doing several things. I
pulled brainbox and dried it out with a hair dryer I have
pulled both spark plugs and spark plug wires turn the car
over until all water was out and replaced with new spark
plugs and new wires I pulled the air filter to try to start it it
still will not start I hear the fuel pump start when I turn the
key to on but not over. I don't know what else to do. Can
somebody tell me anything else I might be able to do to get
my van working again cuz this is my only transportation.
