the jet pump is a clever bit of kit it uses energy from the main pump to transfer fuel over to balance it out being a saddle tank arangement if its not doing its job then its faulty unless its not been installed correctly. there are no electrical connections only the level sensor. and pipework
fuel starvation or your auto choke isnt engaging pump the gas pedel a few times when starting get some fuel through the jets, have you been running the car on low fuel this brings up the sludge from the bottom of the tank and blocks the jets try some jet cleaner in your tank when its running this will clean out your jets and give you better acceleration and fuel economy
may be start by checking all fluid levels including the windscreen washer bottle if it has headlight wipers check that there is not a seprate washer bottle 4 them.also check that its not a light reminding u that the rear fog light is on some european cars have a bright red light in the drivers side rear tail light for heavy fog conditions
1. ensure that the wash fuse is ok.
2. click the ignition to on but do not start motor. and check for pump noise if not noise then suspect fuse pump, pump connection or washer switch.
3 if you can hear pump. check washer fluid bottle is not empty. check for any dirt in the bottle blocking the pump or pipe.
4 check pipes to washer jets are clear and connected.
5. check washer jets are not blocked, use a wire strand from a wire brush to clear.
is it cold? check that the fluid has not frozen in the system. get the vehicle in the warm and thaw out system once this is down top up with a good windshield antifreeze fluid.
work backwards through the sytem. disconnect water jet pipe and switch on if not fluid. move back to water container see if fluids comes or from there if so then pipes or jets are blocked.
if not pump is defective - blocked or not getting power..
It could be something simple like a blocked jet. If you take one of your wife's fine sewing needles and gently puch it into the centre of the nozzle it will work again if that is the probelm. It could be a problem with the motor and pump but they are durable so I would try the needle trick first.
