Two different procedures may be used to drain fuel tank: through the fuel fill fitting on tank, or using a diagnostic scan tool. (YOU DO NOT HAVE TOOL)
The quickest draining procedure involves removing the rubber fuel fill hose (3) from fuel tank fitting (7).



1. Release fuel system pressure.(PRESSURE IZED LINES GOING FRONT)
2. Raise vehicle.
3. Thoroughly clean area around fuel fill fitting (7) and rubber fuel fill hose (3) at rear of fuel tank (8).
4. Loosen clamp (9) at tank fitting (7) and disconnect rubber fuel fill hose at fuel tank fitting. Using an approved gas
holding tank, drain fuel tank through this fitting.
Loosen clamp (9) and disconnect rubber fill hose (3) at tank fitting (7).
2. At rear of tank, disconnect fuel pump module electrical jumper connector (5) from body connector (6).
3. At rear of tank, disconnect EVAP lines (2) and (3) from lines (1) and (4).
4. At front of tank, disconnect fuel and EVAP lines (9) and (10) from lines (11) and (12).
5. Support tank with a hydraulic jack.
6. Remove bolts (1) and (2) at right side of fuel tank.
7. Remove bolts (3) at left side of fuel tank.
8. Lower tank for removal.
9. If fuel tank is to be replaced, remove fuel pump module from tank. Refer to Fuel Pump Module Removal/Instal-
lation procedures

here is the Cherokee page.
read chapter, 14, page 19 on..
shows all way there, and is not easy.

pump dead
is there 12vdc to pump cranking, (no? then dont do this)

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.

On some cars there is a drain cock on the tank, if not on yours you just remove the fuel line an lit drain out from there. If you have a Chiltons or Haynes manual for your car it will show all these points for your car. Last resort call dealer or a local mechanic they can tell you right away.

You need to clear all the OBD 2 codes from the computer.
Has to be cleared with a OBD2 code reader

was it tuned up too

The valve regulating the water flow to the heat exchanger could be broken. It needs to be replace.

Hi
If your engine warning light has come on this is indicating there in a serious problem and the limp mode has been switched on to safe guard the engine. It could be a number things, but I'll give you some basic things to look at which may help you.

1. Check all fluids are are the correct levels - engine oil, radiator water level in overflow tank usual beside the radiator.
2. Also check transmission fluid level if it is an automatic, from the dipstick.
   

If all these are ok then check these areas:

1. Air Filter and housing has no blockage.
2. Fuel filter may need replacing or water separator is filled with water, loosen valve at the bottom of fuel filter and drain the excess water. Fuel should not come out just water if there is any.

If all these are ok then there is a problem regarding sensor faults, fuel pump timing, and further in depth diagnosis will be needed. Hope this is helpful, let me know how you get on.

heater coil in side dash has leak anti freeze is poison you could try stop leak in radiator with the heater on hot i like the powder type it might seal till you get the coil replaced

just put a bottle of octane booster in the tank and then use the fuel you bought. no harm will come to the car.

Disconnect fuel hose that connects to fuel rail on the motor. Connect that hose to a rubber hose and lead it into a container. Then you have 1 of 2 options. First is just turn the key on for 3 seconds, turn off, then on again, etc etc etc, till tank is empty. This will take a while but easy if tank is almost empty. 2 would be to find the power to the fuel pump. Run a live wire from battery to fuel power wire and pump will run till you disconnect power. It can be a pain in the but to find the power wire though.
