I have a few questions for you.
1. Did you verify the pumps are working? If so check the hoses for kinks and check the nozzles for clogs. Use a pin or needle to clean the nozzles if they are clogged.
2. Do you have voltage to the pumps? You can check with a volt/amp meter.
3. Have you verified that the fuse(s) is/are not blown, If so replace and find out why the fuse blew. Look for chaffed wires. Pay close attention to wires under clamps. Sometimes the clamps can rub the insulation and cause a short.
Sometimes a fuse will blow for not apparent reason other than it's just old or all the stars have aligned perfectly to cause it to blow. I have had that happen on two occasions.
