Lpg converted engine wont run using lpg without gasoline in tank


It is normal. All LPG converted engines start with gasoline. Then when they reach 2000 rpm move on LPG system.
If you want to start directly with LPG must call a professional to modify your installation.

Where can I find schematics for the fuel tank of a 96 honda passport


Removing a Fuel Tank for Servicing The procedure for removing a fuel tank varies depending on the vehicle make and year. Always follow the procedure in the vehicle manufacturer's service manual.
WARNING Wear safety glasses and do not use a drop light. Liquid falling on the hot glass can cause the bulb to explode. If it is accidentally dropped or has a bad switch or loose connections, it can cause a fire.
  • Before removing the tank, remove the battery ground cable to avoid an accidental spark.
  • Relieve the fuel system pressure, and drain the fuel tank.
    • Gasoline weighs about 7 pounds per gallon. A full tank could easily weigh in excess of 100 pounds. Attempting to remove it while it is full could result in a dangerous gasoline spill or an injury. Remember, gasoline vapor is extremely flammable.
  • Raise the vehicle on a hoist, or lift the vehicle with a floor jack and then lower the chassis onto jack stands.
  • Use compressed air to blow dirt from the fuel line fittings and wiring connectors.
  • Remove the fuel tank wiring harness connector from the body harness connector.
  • Remove the ground wire retaining screw from the chassis if there is one.
  • Disconnect the fuel lines from the fuel tank. If these lines have quick-disconnect fittings, follow the manufacturer's recommended removal procedure in the service manual. Some quick-disconnect fittings are hand releasable, and others require the use of a special tool.
  • Wipe the filler pipe and vent pipe hose connections with a shop towel, and then disconnect the hoses from the filler pipe and vent pipe to the fuel tank.
  • Unfasten the filler from the tank. If it is a rigid one-piece tube, remove the screws around the outside of the filler neck near the filler cap. If it is a three-piece unit, remove the neoprene hoses after the clamp has been loosened.

WARNING Do not heat the bolts on the fuel tank straps in order to loosen them. The heat could ignite the fumes.

  • Loosen the bolts holding the fuel tank straps to the vehicle until they are about two threads from the end.
WARNING Gas tanks should be filled with an inert gas, such as CO2, before any welding takes place. Even if a tank has been thoroughly flushed of gasoline, the tank may still contain flammable vapors. Attempting to weld such a tank may result in an explosion.

My 2004 K1500 4.8 4x4 won't pass inspection, codes 420, replaced cat bank 1, code 455 now? I had GM dealership do service bulletin on heater blower motor relay and now "service air bag" light is on as...


The only solution I can offer is temporary and could help you at least pass inspection.

  • When you fuel tank is near empty.
  • Fill your car with 3 Gallons regular gasoline and 3 Gallons E85 gasoline.
  • Erase the error codes and drive around for a little while.
  • Then get the inspection done.
  • After you pass inspection fill the car the rest of the way with regular gasoline.


WARNING: This is a last resort effort. Prolonged use of Ethanol (E85) in engines not designed for it can deteriorate rubber fuel lines, oxidize aluminum, and dry gaskets causing them to crack.

Need a wiring diagram for 1989 chevy 1 ton dually(crew cab)for dual tanks. fuel gauges aren't working from burned wires


I have found the wiring diagrams online to be unreliable -- they sometimes are listed under the wrong model or year, and have often caused me a lot of frustration and confusion. It is possible that you can get one, but for the sake of reliability you should probably pick up a Haynes manual for your truck - - it will have all of the diagrams you are looking for, as well as many other useful bits of information for repairing your truck. You might have more luck finding the diagram than I ever did ... but I still recommend picking up a Haynes manual for your future reference -- at under $30 US it can save you thousands in mechanic costs (if you have the time and tools to do your own repairs). These manuals are available at most auto-parts stores and larger bookstore chains.
If you are unable to find the Haynes manual for your truck, or just have your mind set on getting one online, you should include a bit more information to assist with your search:
1. Make, Model and year of your truck (which is here) 2. Engine size / type (is it a diesel, turbo-diesel, hemi, standard 5.7 L gasoline engine?) 3. Are there any engine or other upgrades that could affect the wiring? 4. Is it your entire wiring harness that needs replacing, or just the fuel gauge wiring? 5. Does the truck have an automatic or a manual transmission? (this can affect the wiring harness style and connections). 6. Do you know why the wiring burned out in the first place? (so you can possibly avoid the same issue in the future by changing where the wires sit when connected is possible)
I wish you the best of luck ... if you can't find the Haynes manual, please reply with the above information and I will do my best to help you find the appropriate wiring diagrams for your truck.

Put $15.00 gas in my 2001 Esteem, and the fuel gauge didn't move? I just purchased this car last week, and really love it. But I really need to know how much gas is in it! Thanks


You have to drop the gas tank to fix this. Let me know if your up to it and I will help you through it. Also the level switch is part of the sending unit, With the fuel pump. New will be seberal hundred dollars.Installed at a garge will be $500. to $700.00. If you want to replace just the switch , you can get a sending unit at a junk yard for around $75.00

How do you drop the fuel tank off of the car


will need to unhook the filler connection. unhook all wires connected to the fuel pump on top of the tank, unhook gasoline hoses from the fuel pump and then take off the straps holding the tank in place. Dirty job so blow as much dust and dirt off as possible before taking the pump out.

Fuel Gage


The analog gas gauge is an electrical meter movement and while they rarely fail, they can. Most gauges in the last few decades do not return to 'E' with the power off, they just hang out wherever they happen to be when the ignition is turned off; yours isn't doing either.
The sender is a variable resistor that controls the current flowing through the meter and most (there are exceptions) will be at maximum current with a full tank of gasoline. When this is failing, normally the reading will at first be erratic (the wiper of the sender is losing contact intermittantly) then it will go to one or the other extreme, depending on how the sender is wired. To have one fail instantly is pretty rare.
Before replacing anything, I would check wiring and connection plugs to make sure it isn't a matter of corrosion causing one or the other lines to cease conducting. Since there isn't much current flowing here, a bad connection can cause it to quit conducting.
You should have the wiring diagram and a multimeter to check continuity.
