Replaced water pump in my 97 aerostat van and now it won't crank. Did everything was told to do. No water leaks, thermostat won't open because van only runs a few seconds before it dies. I unplugged the timing senser while battery was hooked up. Duh. Lol. Anyways need help.

 

Just to correct your post..........

"............van only runs a few seconds before it dies.........."

You have crank, you have a "No Start" condition.

I really don't know the Areo van, but I'll suggest that you double check all the electrical connections, that there tightly connected. One from the crank sensor/distributor or IAC, could have been knocked loose while you we doing the water pump.
