Is there a filter in the line before it gets to carb or fuel inj.

  • John Connell

    There is a fuel filter inline between the twin tanks (Lines) and the fuel pump. The engine ran without this problem before repair on the loader but not for at least 6 mos. I guess the next step is to replace the filter and check that the lines are running freely all the way to the pump. Let me know if you have any other thoughts. I appreciate your response. Thanks

    Replacing the filter is the best place to start. However John,on this model,bthere may be another filter just before you get to the engine. I am assuming the fuel pump has good pressure on it (flow of fuel )

My 4514 Honda has a snow blower for the winter . It keeps stalling and the fuel pump never shuts off so I guess isn't pressurizing . I pulled the fuel line at the carb & it is pumping gas ....

sounds as if there is sticky gum in the carb that is keeping the float from seating unless it is hot enough to unstick. Take the carb bowl off and examine it for gum (real old gasoline will do that.

Occasionally, when I start the vehicle the engine will just continue to turn over but there's no gas getting to where it needs to be. Usually, if I keep pumping the accelerator, you'll hear t

Sounds like a fuel pump issue but could be many other things too. I would start by replacing the fuel filter, it's possible its not letting in as much fuel as needed. Spark plugs are another possibility, I'd change them out if they're more than a year old (as your car gets older it will blow more oil and the spark plugs get fouled much sooner). It could be compression too, you'll need to pressure test each cylinder and verify compression is within spec (if it's not, that's a BIG repair). Also try lower octane gas, it actually ignites faster than high octane gas.

1998 Ford Escort Se 2000cc SOHC will difficultly start the first time then has to set 30 - 40 minutes before it will start again

Holding the gas pedal to the floor will cause the PCM to put the fuel injection system into clear flood mode , cutting the amout of fuel going into the engine . Pumping or pushing on the gas pedal while cranking the engine over does nothing but allow more air into the engine , it's not giving it more gas . The computer has a set program it follows at start up . It's not like a carburetor ! Fuel pressure regulator .

1994 Toyota Camry XLE replaced fuel pump & filter car starts & idles but boggs out and cuts off when pressing gas pedal?

have you pulled codes or checked the fuel pressure? It could be a host of things, like a clogged air filter restricting the flow of air into the engine, a bad air meter, clogged injectors, etc. Engine codes will help you start narrowing things down.

Has the engine air filter ever been changed?

Removed gas tank guard now won't start

Overtime, Jeep Grand Cherokee fuel tanks develop rust and accumulate sediment. This is especially true if the tank sits empty for a period of time. Rust and sediment can break loose and cause clogged filters. When the filter is clogged, the engine does not receive the amount of fuel required to operate. The fuel tank can be cleaned out; however, replacing the tank is easier.
  • 1 Apply the parking brake.

  • 2 Remove the gas cap.
  • 3 Remove the fuel pump relay from the power distribution center under the hood. Look at the underside of the power distribution cover, and locate the fuel pump relay.

  • 4 Attempt to start the engine, cranking the engine for several seconds.
  • 5 Turn the ignition to "Off." Install the fuel pump relay.
  • 6 Disconnect the negative cable from the battery.
  • 7 Lift the fuel tank into position, using the jack.

    8 Attach the fuel filler hose and vapor return hose to the fuel tank.Tighten the clamps with a Phillips screwdriver.

  • 9 Pivot the fuel tank retaining straps into position. Tighten the fuel tank retaining strap nuts with a socket and ratchet. Lower the jack.

  • 10 Connect the fuel pump electrical connector, the fuel filter line and the fuel return line. Push the fuel line retainer into the chassis.
  • 11 Raise the heat shield. Install the mounting bolts. Tighten the mounting bolts with a socket and ratchet.
  • 12 Install the tow hooks or trailer hitch, if equipped.
  • 13 Lift the skid plate into position with the jack. Tighten the skid plate mounting bolts with a socket and ratchet.
  • 14 Attach the electrical service connector to the bumper with a socket and ratchet.
  • 15 Raise the jack and remove the jack stands. Slowly, lower the vehicle.
  • 16 Pour the fuel into the gas tank. Connect the negative battery cable.
  • Buy Custom car Parts.

    My first thought would be: If you repaired an emissions hose, take the car back to Auto Zone (or another parts supplier) and let them tell you what code comes up now. You eliminated one problem, now you have to find another.
    I wouldn't do a fuel pump without more information.

    Okay, you need to make sure the fuel pump is getting power and that you have the lines hooked up correctly. Also, when you replace fuel pumps you need to remove the air cleaner and use starter fluid to get the engine started.

    Gas is not getting from gas tank to Carburator .. 1987/88 Wrangler 42. engine was recently rebuilt .. gas tank sending unit was removed and repaired .. fuel line was blown out with air compressor. fuel...

    Make sure you have the lines attached correctly on the sending unit and make sure there no small holes in the line. The pump pulls fuel and will draw in air. To make sure the pump is good, attach the tank side to a container of fuel and see if the engine starts. (keep the container below the pump or it can start a siphon and appear to be OK when it's not)
    If the repair to the sender involved soldering up a line leak, make sure the line is not still leaking and that the line has not filled with solder.
    It's a really simple system...there are no "trick" items there. If everything is intact and the pump is good, it has to work!!!
