if the engine turns over, but just doesn't start, you need to do some checking, check for spark from the coil, or coil packs, if that checks out ok, have the crank and cam shaft position sensors checked, timing belt, computor. I know it's a pain, but I have worked on cars for 40 years, something like this you have to use process of elimination, without testing, you could replace things you don't need. ( expensive) good luck).

SOURCE: I want to drain my gas tank because it has 6 year gas in it.

If you remove the line just prior to the carberator or the fuel injection line then turn the key on you should get a flow of gas.

Any time you are working with open fuel and fumes it is dangerous so make sure the area you are working in is well ventilated.

Apollo, I would first pull all the plugs out and give a little squirt of something like seafoam or even just a bit of engine oil into each cylinder, you may have lost the seal between the rings and cylinder walls and this will help. You also need to confim for shure that you are not getting fuel before you worry about the pump. You can check this at the fuel rail, either by opening up the line, or in some cases you may even have a schrader vale(like a tire valve) on the line that you can press. I suspect that you do have fuel, but the injectors are not oppening due to the old fuel sitting in them for so long. These can be removed and taken to a shop that cleans injectors, and then reinstalled with new seals. And yes I do belive that there is a fuel pump relay in the fuse area, you need to do a search to find out wich one. These can be jumpered to activate, but untill you have done everything else i wouldn't worry about it. Oh, I asume that you have checked for spark? If not, you can pull a plug out and with the wire attached you can hold the base of the plug against the block, while wearing gloves, and see if you get a spark when some one cranks it over. Remember, you must have spark, compression and fuel at the right time in the proper ammount, and it will run.

SOURCE: I need to drain the gas tank on my 1998 Chev.

Unbolt the bed bolts, remove the tailgate, unplug the light harness, and unbolt the fuel filler where it bolts to the bedside and get a couple of buddies to lift off the bed. That way you don't have to drop or drain the tank. It's much faster, on my truck it's only four bolts and the bed is not that heavy.

http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

i have the KJ pages here. (line # messed up)
Two different procedures may be used to drain fuel
tank: through the fuel fill fitting on tank, or using a
scan tool.
The quickest draining procedure involves removing
the rubber fuel fill hose (7) (Fig. 25) from fuel tank
fitting.
As an alternative procedure, the electric fuel pump
may be activated allowing tank to be drained at fuel
rail connection. Refer to DRB scan tool for fuel pump
activation procedures. Before disconnecting fuel line
at fuel rail, release fuel pressure. Refer to the Fuel
System Pressure Release Procedure for procedures.
Attach end of special test hose tool number 6541,
6539, 6631 or 6923 at fuel rail disconnection (tool
number will depend on model and/or engine application).
Position opposite end of this hose tool to an
approved gasoline draining station. Activate fuel
pump and drain tank until empty.
If electric fuel pump is not operating, fuel must be
drained through fuel fill fitting at tank. Refer to following
procedures.
(1) Release fuel system pressure.
(2) Raise vehicle.
(3) If equipped, remove fuel tank skid plate.
(4) Thoroughly clean area around fuel fill fitting
(6) (Fig. 26) and rubber fuel fill hose (1) at side of
fuel tank. After cleaning, loosen fuel fill hose clamp
(2) at tank.
(5) Before removing rubber hose (1) (Fig. 26) from
fitting, note hose orientation while referring to marks
(3) and (4).
6) Disconnect rubber fuel fill hose at fuel tank fitting
(2) (Fig. 27). Using an approved gas holding
tank, drain fuel tank through this fitting.
Tank Removal
(1) If equipped, remove fuel tank skid plate and
tow hooks. Certain equipment packages will also
require removal of the trailer hitch. Refer to Tow
Hooks, Trailer Hitch or Skid Plate in 23, Body for
removal/installation procedures.
(2) Disconnect and separate fresh air tube (6) (Fig.
28) quick-connect fitting.
(3) Disconnect air tubes at front of NVLD pump
(9) (Fig. 28).
(4) Disconnect NVLD pump (9) (Fig. 28) electrical
connector.
(5) Disconnect fuel pump module electrical connector
jumper. This is located near front of fuel tank.
(6) Support tank with a hydraulic jack.
(7) Remove 4 fuel tank strap bolts (10) (Fig. 28) (2
at front of tank; 2 at rear of tank), and remove both
tank support straps.
(8) Carefully lower tank a few inches.
(9) Continue lowering tank while guiding remaining
hoses and lines through plastic isolator sleeve (3)
(Fig. 29).
(10) If fuel tank is to be replaced, remove NVLD
pump and fuel pump module from tank. Refer to
Fuel Pump Module Removal/Installation procedures.
end , tank out.

Drain Diesel from gas tank


No easy way, if you can get an electric pump, or a pump attachment for a power drill. Remove the fuel line, either at the fuel filter or the fuel rail, connect the pump with a bridging piece of hose, and let the pump do the work. Refill with a couple of gallons of petrol. Vehicle might smoke a little till all traces of diesel are gone. Diesel in petrol is not as bad as petrol in diesel. As you did not run the engine very little diesel will get up to the engine. Good Luck.

2001 crystler town & country fuel pump


The Fuel pump is in the tank. The only thing I disagree with in emissionwiz post is whether to drain the tank or not. Chrysler started putting drains on the tanks in 2000 to make this easier when they went to a plastic fuel tank. I would drain the tank from the drain, disconnect the wiring then drop the tank to replace the pump. This all assumes that you verified that the fuse in the interior panel is not blown and the fuel pump relay in the power distribution box under the hood is still good.

Steps replacing a 1985 grand marquis fuel pump for first time alone thanks


See Figure 1
Two different electric fuel pump configurations were used on fuel injected models. One consists of a low pressure in-tank boost pump in conjunction with an external, frame-mounted high pressure pump. The low pressure pump is used to provide pressurized fuel to the inlet of the high pressure pump and helps prevent noise and heating problems. System pressure is controlled by a pressure regulator mounted on the engine.
The other configuration consists of an in-tank high pressure pump which does not utilize a boost pump.

I need to drain the gas tank on my 2002 dodge


Hopefully your not attempting to replace a fuel pump in this vehicle or the tank its self?

There is no drain plug you have to purchase a fuel extractor pump. They are manual or electric. You put pump hose in tank threw fill up and start pumping the fuel out into its container.
CAUTION; WEAR EYE AND BREATHING PROTECTION. KEEP FIRE EXTINGUISHER'S HANDY.

How to rmove fuel from fuel tank of 2000 chevy express van?


Some fuel tanks have a drain **** that will allow you to drain all of the gas neatly. If you have a drain ****, it will be located at the lowest point on the tank. Loosen the valve and allow the gas to completely drain.
If your tank has no drain ****, you'll have to drain it by removing one of the fuel lines. The rubber hose that exits the tank at its lowest point will drain the tank fully. It will either be connected to an electric fuel pump, fuel filter, or to a hard fuel line that goes to the front of the car. Loosen the clamp on the end of the line that connects to the gas tank. Pull the hose off and allow the gas to run out of the tank into your container until it is drained completely.

Drain the fuel


there is no drain plug. you may have to drop the tank and tip it over to drain in to a tub.
or you can disconnect the fill tube from the tank it self from under the car and put a hose in it , and attach an electric fuel pump to it. pump it out that way.
you can get a cheap external pump from almost any parts store.

I've got bad gas and need to know the easiest way to drain the tank or otherwise fix the problem.


The tank will have to be removed from the vehicle and completely dried out.Gas tanks no longer have drain plugs as they did 50 years ago.Remove the fuel pump from the top of the tank,and thoroughly clean the tank with brake cleaner and compressed air and let air dry for awhile.The fuel pump and filter will need to be replaced with new,and after all the reinstallation,the fuel line must be disconnected at the engine,and the line flushed with new,clean gasoline as well as the return fuel line.Spark plugs will have to be replaced also.
