Pump has not pressure and will not restart automatically

When you put your key in, don't turn it all the way but to the point where everything powers up. You should hear a hum from the lower rear that lasts about 3 seconds. That's the fuel pump. If you don't hear that, it could be the fuel pump.

IF you start pumping too soon then that happens. You need to turn the unit on and then wait for the zero to stop flashing before you pump it up.

The blinking heart symbol indicates that the unit is slowly decreasing the pressure in the wrist cuff. This is when the unit is finding your Diastolic blood pressure. This is a normal symbol on most automatic blood pressure monitors. When a nurse or doctor uses a manual blood pressure cuff and listens to the blood flow, they will record the systolic pressure when they first hear the heart beat. Then they record the diastolic measurement when they can no longer hear the heart beat.

The manual for the KS-7902 is available here: http://pharmasupply.com/wordpress/pdf/wristman .

I hope this helps.

Did you ever change the fuel pump? most of the time when fuel pump is weak does that on hills, and then is hard to restart

I assume the pump runs when switched on until a preset pressure is reached in the outlet when it cuts off, remaining on standby until the pressure falls due to a demand for water when it automatically restarts.

To achieve that automatic function there must be a pressure switch in the outlet side of the pump and that or the associated circuitry is where the fault must be as the pump seems to run ok when reset is pressed.
If it is modern it is likely electronics are involved and it would seem more likely those are at fault than a faulty pressure switch which could be expected to remain faulty all the time.

Another possibility is the motor is overheating due to a fault or due to the duty cycle being exceeded and the safety cut-out must be manually reset.

Not unusual for fuel pumps to begin to fail once they are heated up from running. First thing in the morning pump is cool, then as you drive, it heats up and begins to lose pressure. After sitting a 1/2hr-1hr, it may start again and run fine for a short time and start to act up again. Had similar problem and found good fuel pressure when tank and pump cool, but lost pressure once vehicle driven a distance and pump heated up. The hotter the weather, the shorter the distance I could drive. If you can somehow set it up to have fuel pressure checked when it starts to act up, that would certainly help confirm if fuel pressure is the culprit.

A flashing oil light usally means low oil pressure. If the oil pressure drops below a set point the light will contiune to flash even if the pressure rises back up to normal until you resart the car. Start simple and check the oil. If low then add. Keep an eye on it, if your losing it, its going somewhere, exhaust, or out a seal or if you went to jiffy lube, probably out of the oil filter due to it not being tightened. If oil is ok, your oil pump may be bad. That job is a little complex.

In the past, waiting for the fuel lines to pressurize was the only way to start fuel injected cars. Newer cars are designed to keep the line pressurized after you turn it off, and there is no need to pressurize upon restarting. Seem like your vehicle is losing the pressure gradually after shutting it off. Gasoline pressure can only be lost 2 ways: 1) A broken line, with fuel dripping to the floor, which, obviously you can see and smell, or gas going back into the tank due to a faulty pump or pump installation.

the automatic pressure switch does restart the water pump when the valave is open?

I think your diagnosis is correct. Tighten all fittings and the problem may disappear. By the way if you go to the website below you can download a service manual for your bike. FREE. I really love free. It is a big file and will take maybe 10 to 15 minutes to download. Download time is dependent on the speed of the computer, etc.

Pleas rate this solution. Thanks
