Changed my fuel pump on my 06 ford 500 now I can only start if I hold the fuel reset and it doesn't stay running for very long why does that happen how can I fix this

By fuel reset do you mean inertia fuel cut off switch ? Why did you change the fuel pump ? Are you aware of the fuel pump driver module ! Your vehicle has a electronic returnless fuel system . It is computer controlled , has a fuel rail pressure an temp. sensor .
The FRPT sensor measures the pressure and temperature of the fuel in the fuel rail and sends these signals to the PCM. The sensor uses the intake manifold vacuum as a reference to determine the pressure difference between the fuel rail and the intake manifold. The relationship between fuel pressure and fuel temperature is used to determine the possible presence of fuel vapor in the fuel rail. Both pressure and temperature signals are used to control the speed of the fuel pump. The speed of the fuel pump sustains fuel rail pressure which preserves fuel in its liquid state. The dynamic range of the fuel injectors increase because of the higher rail pressure, which allows the injector pulse width to decrease.
Inertia Fuel Shutoff (IFS) Switch The IFS switch is used in conjunction with the electric fuel pump. The purpose of the IFS switch is to shutoff the fuel pump if a collision occurs. It consists of a steel ball held in place by a magnet. When a sharp impact occurs, the ball breaks loose from the magnet, rolls up a conical ramp and strikes a target plate which opens the electrical contacts of the switch and shuts off the electric fuel pump. Once the switch is open, it must be manually reset before restarting the vehicle. Refer to the Owner's Literature for the location of the IFS.
The FPDM receives a duty cycle signal from the PCM and controls the fuel pump operation in relation to this duty cycle. This results in variable speed fuel pump operation. The FPDM sends diagnostic information to the PCM on the fuel pump monitor circuit. For additional information on Fuel Pump Control and the Fuel Pump Monitor, refer to Fuel Systems in this section.
Electronic Returnless Fuel System (ERFS) The electronic returnless fuel system consists of a fuel tank with reservoir, the fuel pump, the fuel rail pressure (FRP) or fuel rail pressure temperature (FRPT) sensor, the fuel filter, the fuel supply line, the fuel rail temperature (FRT) sensor, the fuel rail, the fuel injectors, and a Schrader valve/pressure test point. For additional information on the fuel system components, refer to Engine Control Components in this section. Operation of the system is as follows:
  1. The fuel delivery system is enabled during crank or running mode once the PCM receives a crankshaft position (CKP) sensor signal.
  1. The fuel pump logic is defined in the fuel system control strategy and is executed by the PCM.
  1. The PCM commands a duty cycle to the fuel pump driver module (FPDM).
  1. The FPDM modulates the voltage to the fuel pump (FP) required to achieve the correct fuel pressure. Voltage for the fuel pump is supplied by the power relay or FPDM power supply relay. For additional information refer to Fuel Pump Control and Fuel Pump Monitor.
  1. The fuel rail pressure (FRP) sensor provides the PCM with the current fuel rail pressure. The PCM uses this information to vary the duty cycle output to the FPDM to compensate for varying loads.
  1. The fuel rail temperature (FRT) sensor measures the current fuel temperatures in the fuel rail. This information is used to vary the fuel pressure and avoid fuel system vaporization.
  1. The fuel injector is a solenoid-operated valve that meters the fuel flow to each combustion cylinder. The fuel injector is opened and closed a constant number of times per crankshaft revolution. The amount of fuel is controlled by the length of time the fuel injector is held open. The injector is normally closed and is operated by 12-volt VPWR from the power relay. The ground signal is controlled by the PCM.
  1. A pressure test point valve (Schrader valve) is located on the fuel rail and is used to measure the fuel injector supply pressure for diagnostic procedures and repairs. On vehicles not equipped with a Schrader valve, use the Rotunda Fuel Pressure Test Kit 134-R0087 or equivalent.
  1. There are 3 filtering or screening devices in the fuel delivery system. The intake sock is a fine, nylon mesh screen mounted on the intake side of the fuel pump. There is a fuel filter screen located at the fuel rail side of the fuel injector. The fuel filter assembly is located between the fuel pump and the pressure test point/Schrader valve.
  1. The fuel pump (FP) module is a device that contains the fuel pump and the fuel sender assembly. The fuel pump is located inside the reservoir and supplies fuel through the fuel pump module manifold to the engine and the fuel pump module jet pump.
  1. The inertia fuel shut-off (IFS) switch is used to de-energize the fuel delivery secondary circuit in the event of a collision. The IFS switch is a safety device that should only be reset after a thorough inspection of the vehicle following a collision.

What does it mean if the bathroom tap does not work but all other faucets in the house work.

The valve may be off under sink. Or faucet valve may be broken.

Tank sweats profusly

Sweating tank can cause moisture problems inside bathroom.
Sweating is caused when incoming water temperature is hotter or colder than air temperature inside bathroom.
You can verify this by not flushing tank for several hours and notice that sweating stops once water inside tank warms or cools to same temperature inside bathroom.
Problem can also be cause when there is not enough ventilation inside bathroom and water on tank does not evaporate.

To solve problem:
1) Increase bathroom ventilation and add dehumidifier or fan so condensation drys.
2) Insulate interior of tank. Empty water and let tank dry. Tape off moveable parts. Use can of spray foam and insulate inside of tank. Let foam dry and cut away excess foam.
3) Add tempering tank or staging tank inside room to pre-heat/cool water before it enters tank

Hot water tank does not work when shower is on, it does however work when the faucet in bathroom is on. It quit working in the shower about a month ago.

    If inlet water temperature is over 70°F due to geographic location, water maybe very hot out of the tap. This requires a lot of cold water to be added with it in order to attain a useable hot water temperature. The addition of too much cold water will overpower hot water demand from the tankless water heater. This slows the flow within the tankless water heater, decreasing it below activation point, which shuts off the heater. The end result is nothing but cold water coming out of the outlet. See: TWH E2-04 Overcoming fluctuating temperatures [PDF].
    If the water pressure in the home is erratic and the water flow is not consistent while a tap is opened, then the temperature of hot water will fluctuate. The minimum water pressure for the home should be 30psi or greater. For people on well systems the minimum pressure range is 30-50psi. The use of a pressure reducing/regulating valve is an effective way to maintain constant water pressure to the water heater. Watts brand 25AUB- ¾" or N35B-¾" pressure reducing/regulating valves or equivalent is suggested.
    Major changes in flow rate can adversely affect the output water temperature of the heater. Increases from one major fixture running to multiple fixtures running at one time can cause the temperature to fluctuate. Stay within the heater's specifications. See: TWH E2-03 Outlet temperature vs. flow rate [PDF].

No hot water in sink and shower

it sounds like 1(or more) of the motorised valves arent working.find the valve and make sure you are getting power to it via a tester,if so then it probably needs the head on the motorised valve changed

Can't get hot water heater to work - Rinnai Infinity 18

If you can get to the gas valve make sure it is in the on position and not in pilot or off. Does it sound like
a spark ignition system? Even though you say the gas valve is on, by code thered should be a gas shutoff valve located within site of the unit. Follow the
gas pipe until you find such a valve and make sure its on

New House The women is complating that then she shower at any of her bathroom tub shower unit the faucet become cold for a little while on all her Moen chateau faucet. We have change all valve cartrige

The problem is most likely with "the back pressure from the flow restrictor in the showerhead causing the spool in the cartridge to sense a false pressure drop. This is forcing the spool to shift, restricting a full hot water temperature from coming out." Believe it or not, I got this information from Moen. Their solution was to send out a valve without the multi settings of the original and that didn't work very well. I can only tell you that I used an older showerhead without the water saver feature and the valve and cartridge worked fine. The problem your having is with the cartridge/showerhead combination and short of using an older showerhead there is not a satisfactory solution. Maybe your plumber has a better solution.

Do not know how to make the shower get hot

Check the water heater to see if the outlet shut-off valve is closed slightly. Maybe there is a valve just for that particular bathroom in the attic.

If neither of these are the case then it is time to check the washers and o-rings inside of the valve body. THis is accomplished by turning off the water supply where it enters the house, removing the handles, loosening the packing nut, pulling stem out and changing the washers. The replacement is just the opposite.

Hope this helps.
