Pump has no pressure

nozzles do plug up you know many have screens behind them in the hole they screw into

Electric Fuel Pump REMOVAL & INSTALLATION Non-Supercharged

1. Disconnect the negative battery cable and properly relieve the fuel system pressure.
2. Remove the fuel tank and place it on a bench.
3. Remove any dirt that has accumulated around the fuel pump retaining flange so it will not enter the tank during pump removal and installation.
4. Turn the fuel pump locking ring counterclockwise and remove the locking ring.
5. Remove the fuel pump and bracket assembly. Remove and discard the seal ring. To install:
   
6. Clean the fuel pump mounting flange, fuel tank mounting surface and seal ring groove.
7. Apply a light coating of grease on a new seal ring to hold it in place during assembly and install in the seal ring groove.
8. Install the fuel pump and bracket assembly carefully to ensure the filter is not damaged. Make sure the locating keys are in the keyways and the seal ring remains in the groove.
9. Hold the pump assembly in place and install the locking ring finger-tight. Make sure all the locking tabs are under the tank lock ring tabs.
10. Rotate the locking ring clockwise until the ring is against the stops.
11. Install the fuel tank in the vehicle. Add a minimum of 10 gallons of fuel to the tank and check for leaks.
12. Install a suitable fuel pressure gauge on the valve on the fuel rail.
13. Turn the ignition switch from OFF to ON for 3 seconds. Repeat this procedure 5–10 times until the pressure gauge shows at least 35 psi. Check for fuel leaks.
14. Remove the pressure gauge, start the engine and check for leaks.

Bleach gives off corrosive vapors, so the internal parts of the pump may have corroded over time. Least expensive fix is to disassemble the pump, find and replace any corroded parts, but you'll be tinkering for a day and it may not be repairable anyway. More expensive but faster is to replace the pump - check the GPM rating and find it here for about $60 - $100. Good luck!

Have you unscrewed the end off the wand?Do that and pull the trigger to flush out any debree

Take the strainer at the end of the hose on the tank off. Throughly clean it. I used an old tooth brush, then ran hot water through it several times. Also drained the tank and flushed it out 3-4 times with fresh water, then ran fresh water through the pump for several minutes

Hope this helps

There is an o-ring inside that is probably bad. I tore my pump apart and found it and repaired it. My sprayer was about two years old as well.

I don't think that these pumps run dry very well ... most likely you ruptured a diaphragm by running it dry. How long did it run dry? ... take it apart and see if the diaphragm or valves are damaged. You will need to replace them before the pump will work.

at the end of the pump little square box with one pillpes head ,take it off and there is another screw in there turn it until it works,

Disconnect the sprayer boom hose from Y splitter, and dd another Y splitter, then reconnect the boom hose to one side of the added splitter. Add a washing machine supply (female/female) to the other side of new Y. now attach garden hose to washing machine line and turn on the water faucet with pump running. This will charge and/or backwash the pump. Once pressure is achieved, turn on the boom and check for fluid movement, then turn the washer supply valve on Y to off, and disconnect. The pump should be primed and be cycling fluid from tank and back to tank. Ready to shift to boom for use. I leave the washer hose and assembly zip-tied onto sprayer for easy future priming, and pump wash between uses.

open up the pump, take out the check valve. wash in dish soap/hot water solution, scrub with old toothbrush, rinse off, reinstall & see if that makes a difference...
