Overtime, JeepGrandCherokee 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.
probably are going to have to remove injectors and clean them as well-I assume if has fresh fuel, the old stuff was varnish after 5 years. You should also remove the fuel line and turn on the key, see if you get a good stream (have a bowl or towel handy to catch it) if not, the fuel pump may be bad, but at least you will have 'bled' the line"-double check your spark at the plugs too.
Hello leah... yes begin by changing the fuel filter. Here is how to do it: 1 Raise the left rear of the vehicle with a floor jack and place a jack stand under the rear sub-frame to support the weight of the vehicle should it fall. Every year people are injured or killed by not following this simple safety step. 2 Turn the ignition off and remove the fuel filler cap to relieve any pressure that has built up in the fuel tank from evaporating fuel. This will prevent fuel from spraying and running down your arm when you release the fuel lines. 3 Use the fuel line quick disconnect tool to remove the lines from the fuel filter by slipping the tool into the quick disconnect until it spreads the retainer and allows the line to be removed. Push the line onto the filter while pushing the tool into the fitting, then pull the line off the filter. When both lines are free, unsnap the filter from the bracket. 4 Snap the new filter into the bracket, noting the markings that indicate flow. Flow should always be toward the engine. Push the line fittings onto the filter nipples until a click is felt, and the line can no longer be pulled off the filter. 5 Prime the fuel system by turning the ignition key to the "Run" position for two seconds and then to the "Off" position. Do this three times and then start the engine. Check the filter quick disconnects for leaks then test-drive.
Fuel flow. Either simply, a blocked fuel line (debris / filter / fouled gas) or an electronic issue. Ever let this Jeep run bone dry on gas? Hopefully not, as doing so can draw a lot of crud into your fuel lines from the bottom of the tank. Electronically, if part of the Jeep "brain" has gone bad, there may not be any fuel being routed to the engine. This most likely needs a Jeep mechanic to repair.
u can do the check the other way around/ disconnect the fuel line that supply the injectors/ put the pipe in a small plastic container to see if fuel is being supplied by the pump and avoid fuel spill in ur engine/ crank the engine for at least 5 seconds see if the fuel squirts with pressure/ if it does then ur fuel pump is ok / blockage is somewhere down the fuel line/ u can check fuel lines by blowing it with air but u gonna need the help of an air compressor.....
best bet would be to drop the tank and clean it out they tend to get rust inside the tank when they sit this long if you decide to drop the tank and find rust inside take a 3 ft piece of heavy chain and shake it around inside the tank to loosen all the rust and clean the rust out really well before putting the tank back in
