  If your Graco Paint Sprayer's engine won't start, several issues could be the cause. First, ensure the engine switch is turned on. Check if you're out of gas and replenish if necessary. Also, verify the engine oil level; if the light on the rear of the engine is on, add oil. Inspect the spark plug cable to ensure it's connected, and replace the spark plug if it's damaged. If water is frozen in the pressure control, return it to an authorized Graco dealer for repair.

  Sherri LewisAug 22, 2025
  If you notice spitting from the gun of your Graco Paint Sprayer, it could be due to a few reasons. First, check for air in the fluid pump or hose, tighten any loose connections at the pump intake, and then prime the pump. Also, check if the tip is partially clogged and clear it. Lastly, ensure your fluid supply isn't low or empty; refill and prime the pump, checking the fluid supply frequently to prevent the pump from running dry.

  If you are finding that the pump on your Graco Paint Sprayer is difficult to prime, consider the following: * Check all hose connections for air leaks and tighten as needed. Reduce RPM and cycle pump as slowly as possible during priming. * If the intake valve is leaking, shut off the pump, relieve pressure, and then disassemble and clean the intake valve, ensuring the ball seat is in good condition. Reassemble. * Consider repacking the pump if the packings are worn. * If the fluid is too thick, thin it according to the supplier’s recommendations.

Why is the fluid delivery low on my Graco GM 5000 Paint Sprayer?
- M
  Manuel SellersSep 2, 2025
  If you're experiencing low fluid delivery with your Graco Paint Sprayer, start by checking the pump inlet screen for clogs and clean it if necessary. Ensure the pressure setting isn't too low and increase it if needed. Also, verify that the engine RPM isn't too low and increase the throttle setting. Check for any blockages in the outlet filter, tip filter, or tip, and clean them. Finally, consider if there's a large pressure drop in the hose; if so, switch to a larger diameter hose.

What causes low displacement pump output on my Graco GM 5000 Paint Sprayer?
- B
  Brian CraigSep 4, 2025
  If the displacement pump output is low on the downstroke, or both strokes, of your Graco Paint Sprayer, there are several possible causes. Begin by checking the pump inlet screen for clogs and clean it if necessary. If the piston packings are worn or damaged, replace them. Additionally, examine the intake valve ball check to ensure it is seating properly; clean and service it as needed. Verify that the engine RPM is not too low, and increase the throttle setting if required. Finally, a worn or damaged clutch could also be the culprit, in which case it should be replaced.
