What do you mean by bad? Bad water pressure? Bad water?
When the turgor pressure is low in a plant it will start to slouch and wilt.
At high pressure the gas become a liquid.
By thinking what's going to happen before you start something
no because snow starts as water but freezes at high pressure and hail forms at lower pressure so it becomes a solid.
In the atmosphere we have air pressure. Low Pressure systems allow for cloud formation, the lower the pressure the more intense a storm can be. So you would get storms around Low Pressure systems. This does not mean that as soon as the pressure in the atmosphere drops cloud start forming immediately, that takes time.On the other hand we have High Pressure Systems, in high pressure systems do not allow for cloud formation, thus, you would have sunny weather around these systems.
Just start the engine.
This is what your filter gauge will read when it is first start with a new and clean filter cartridge / D.E. or sand.
start the truck then while it running pull the fuse for the fuel pump and allow the truck to die then fuel line have no pressure
Not a lot of info to go on here. Was it starting fine before filter change? If so did you remember to relieve fuel pressure before removing old filter? If not, problem may be Ford's infamous safety shut-off switch. Also make sure filter is installed correctly. (Arrow pointing towards front of vehicle.)
It has nothing to do with oil pressure. You probably are starving for fuel at startup. Possibly a defective fuel pressure regulator, clogged fuel filter, or a weak fuel pump. Try turning the key on and waiting for around 10 seconds before starting. I would replace the fuel filter before going any farther.
You need to check the fuel filter and the fuel pressure regulator.
an oil light is designed to come on when there is NO oil pressure or LITTLE oil pressure. that said, when your oil light is on before you start your engine there is NO oil pressure to turn it off until you start the engine.
If you are certain it is low fuel pressure and you've changed the pump and filter the next thing would be the fuel pressure regulator. Also check to make sure none of the fuel lines are crushed closed.
The fuel filter is located on the passenger side of the engine, there is a water sensor located on the filter, so first u must disconnect the connector to the water sensor. Next you will need a large filter wrench to wrap around the filter and unscrew it. Remove the water sensor from the old filter and put it on the new filter (it unscrews). Dont forget to put the new gaskets you get with the filter on the new filter. Next install the filter back on the motor, and reconnect the water sensor connector. Before you can start the engine you will find a button on top of the filter that you must slowly press and release about 30 times to build fuel pressure. Try starting the truck after that, if the truck still wont start keep going back and pressing and releasing that pressure button. Make sure there are no leaks and you are all set.
After resetting the inertia switch and checking for leaks, etc., turn the ignition switch to ON for a few seconds, then to Off. Do this a couple or three times before attempting to start the engine.
IMPORTANT: Do not skip the fuel system pressure release step. Injury and other damage can result! Safety Step! Relieving Fuel System Pressure · allow engine to cool · relieve fuel system pressure · put on your eye protection Before you begin the job of replacing your fuel filter, you must relieve the pressure in your fuel system. A fuel injection system operates under very high pressure. If you don't release this pressure before you start unscrewing fuel lines the result can be explosive. Do this before you attempt to change the fuel filter. To release the pressure in your fuel lines (and fuel filter) you'll need to locate the fuel pump fuse in the fuse box. If you don't have a fuel pump fuse, find the relay that operates the fuel pump. Once you've found the fuel pump fuse or relay, start the car. With the engine running, pull the fuse or relay out. If you pulled the right one, the engine will quickly die. Since it's using all of the pressurized fuel in the system, the fuel lines won't be pressurized when you crack the fittings on your fuel filter. Now that you've relieved the fuel pressure you can remove the old fuel filter. If you didn't do this yet, you must go to the previous step and do it. Very dangerous!
You will need a simple inexpensive tool to disconnect the lines from the filter. Your local auto parts store will have the tools you need. Warning! The fuel system will be under pressure. Before disconnecting the fuel lines from the filter, remove the fuse and/or relay for the fuel pump, then try to start and run the engine until it runs out of fuel. The pressure will be greatly reduced when you disconnect the lines from the filter. Be prepared for some fuel loss. Replace the fuse and/or relay only after the filter is replaced and reconnected. Run engine and check for leaks.
