Also check if the pump is not having any leaks or cracks.also is the pump firm and tight and ends of the pump not worn out.also try with another spare pump to confirm its not pump and something else.this will lead towards the proper fault.
thanks.
Sometimes you need to prime the pump to get it to start working. A lot of pumps that pump water don't draw the water to them as you may think. Fill up the reservoir that holds the water, dump some water down where the impeller spins and turn it on and it should work.
If the mechanisms are all in check and nothing has come loose. You may want to check the motor for activity or voltage if there is voltage. Check the wires if they had come loose. The vacuum should also have outlet for the air see if there is nothing blocking it.
If your pool pump is acting sluggish it may simply be a build up of debris inside the impeller. Cleaning it is simple if you know how.
Step 1 - Check the Impeller
You can check the impeller for clogs by opening the clear cover that is on the strainer basket. Then place your garden hose into the basket and turn it on high. The water should disappear immediately. If it does not, you may have a clog.
Step 2 - Turn off the Power to the Pump
Before actually removing the clog from your pool pump impeller you will need to turn off the power to it. Remove the basket and use a finger to reach into the hole behind the basket to feel for any debris. If it is clogged, go to step 3.
Step 3 - Disconnect the Pump and Motor
Disconnect the pump and motor from the plumbing. Depending upon the make and model of your pool pump you may be able to skip this step. The motor usually just slides away from the pump. Take the pump apart by removing the plastic cover over the motor. This cover generally has several small screws holding it on. Once the cover is removed you will easily be able to see the clog in the pool pump impeller. Just use your fingers or a coat hanger to clean it out. Put everything back together. Once you have it cleaned out you can put the cover back on and put it all back together. Problem solved.
Step 4 - Remove the Plastic Cover
Step 5 - Remove and Clean the Impeller
Step 6 - Clean
Thank you for posting your question here on Fixya.com.
Start with the impeller and strainer baskets. Excessive debris in the basket(s) in front of the pump can reduce flow rates. Another possibility is debris lodged in the impeller vanes. If the baskets do not solve your problem shut down your pump and back out the 6 bolts holding the motor into the pump housing. Pull out the pump end and remove the diffuser covering the impeller (sometimes the diffuser sticks inside the housing and the impeller will already be uncovered). Use a zip tie or something else of similar strength to run thru each vane looking for things such as small toys, marbles, rocks, mulch etc. Once cleared reassemble the pump being careful to align the diffuser back over the impeller and into the pump housing correctly.
If nothing can be found in the impeller and the baskets are all cleaned and still you have reduced return pressure you will have to get into your filter to find the trouble. If you get that far, please post a comment with what brand and model filter you have for more guidance.

This is a Challenger Pac-Fab 1 1/2 hp CF11-N1 !/2 A Pump. The motor is running fine, no problem there. It just will not pump. Where do I go from here?
There is water in the strainer pot. It is designed to "self-prime" under normal operations. Pool pumps are often on timers where they start unattended.
I have been operating this equipment for the past 14 years, so I know the routine things to check. The motor is running normally, the impeller is not clogged, nor are the inlet ports. The internal suction caused by the plugged input strainer has caused something to change, but I cannot find the problem.
