pump stuck in priming mode?

[ndif]

I was actually thinking something like this may be the problem as i don't think my pump is really broken. I tried searching but can you explain exactly where in to the pump i need to inject the water with a syringe? Is it in the main water inlet where the tubing connects or is there some other special location? Also is there any way for me to trigger the pump to run without actually driving the car? I'd like to save myself the time of removing and replacing the front bumper assembly everytime i work on this if possible. thanks
