How to clean "pump stall" on cp1700hp - HP cp1700 Color Inkjet Printer

Stall at highers speeds, yes the fuel filter. I replace them with every pump. Parts stores don't warranty the pump without a new filter. If it stalls at idle, then the air filter, vacuum lines, clean the throttle body and idle air control motor.

check your grounds. I find many easy fixes by cleaning all the grounds around the engine bay. I would also check the ground at the fuel pump connector that wiring is prone to corrosion and breakage

Check fuel filter and fuel pump pressure if nothing change explain with more fetail

throttle position sensor posibly?

I know this is years old, but just in case someone else has this problem....

I just had this problem and fixed it quite easily.

Like you, my ink cartridge flooded the ink bay and caused the printer to complain about a pump stall.

Mine was fixed by taking the cover off (u don't need to) and cleaning all the ink off the white strip.

Basically, there's a white piece of plastic with a metal rectangle on it. it sites to the left of the thing under the print heads (the part doesn't move. Under the big part with all the print heads) and to the right of the paper rollers.

It's also the thing that stops the print heads from moving when they're not to be moving.

Mine was covered in black ink. I cleaned it off and turned on the printer to find it working again and no more "pump stall" messages.

I don't know what the plastic piece is for, but cleaning it fixed my problem. Also there's no "pumps" in the printer (it uses gravity to feed the ink).

Check the steel fuel line under the intake manifold
had one that was almost completely clogged shut with ****
took a month of hunting but found this to be the problem

throttle position sensor , or mass air flow sensor.

Hi
Clean the fuel filter ..... and if the problem does not improve you would need to clean the air filter ELSE the fuel is not pumping well and needs change.

how to clean "pump stall" on cp1700hp

fuel pump could be the cause but also the float in the carby could be not set at the right level and starve the motor at high revs .
