View Full Version : Hard Starting 2001 Jeep Cherokee

March 1st, 2010, 02:04 PM

I have a 2001 Jeep Cherokee, and it has trouble starting. I either have to prime the fuel pump 10+ times, or try to start it for 3+ seconds, then immediately try to start it again and it will start just fine. I am curious if I need to replace the fuel pump, or how to determine if I need a new fuel pump or if there is a pressure leak somewehre. I have had the OBD-II computer hooked up to it does not show any errors.
Thanks.

Bad Checkvalve in the pump assy, common failure.
Install a checkvalve in the gas line close to the tank or replace the entire pump assembly.

if it has the 4.0, it has a fuel filter... change that first, depending the result, you may need to change the pump.

If it is the 4.7 v8, you will need to change out the pump, AKA fuel pump module.

01 XJ's have filters? Where?
Are you referingto the intank filter/sock?

I guess the right thing to do is a leakdown test first.

By the time you've dropped the tank and most likely ruined the pump housing trying to get the filter off, you've spent more time than if you just replaced the pump assy. Don't be cheap, get a Jeep pump.

So I have a similar situation in my '99 WJ with the 4.0. I have found that if I turn the key to the ON position for ½-second before cranking it will fire right up. I'm not going to damage anything doing this, am I? I can't imagine I am.

BTW, it's been doing this for at least the last 60k miles. I'm at 171k and it starts up everytime I do this.


Frank Z

March 1st, 2010, 03:34 PM

Not at all. The fuel system will not stay pressurized forever so you should allow the pump to build pressure prior to starting. Listen to the pump when you first turn the key on, it will run for about 2 seconds and then shutdown untill the engine starts.

Common. Mine has been that way since I bought it. Won't hurt anything at all.

Sorry.. the GRAND cherokee 4.0 has an external fuel filter. The Cherokee does not.(well, it is external, but you have to drop the tank)

Uh, Frank, the 01 XJ has a returnless fuel system. 1 line up to the engine. You don't want to put a check valve in that. Return system, ok, returnless... no.


Frank Z

March 1st, 2010, 04:28 PM

Sure you can. The check valve simply keeps the gas from draining back down into the tank, it doesn't stop or restrict the flow of gas at all. Lots-o-threads on naxja about it.

IIRC, there's a BMW CV that is prefered.


Norco

March 1st, 2010, 04:32 PM

You mean the threads where they say it doesn't work?

Think about it, when the fuel pump duty cycle is commanded lower, the fuel backs up against the check valve. That mod is only for engines with 2 fuel lines.

Should be a 4.0 if it is a XJ. And there is a filter but it is part of the pump assembly and from what I have heard if you are going to take the time to drop the tank you might as well change everything.

Sorry, I don't have time. I know I've seen people having problems doing that with late models and it makes sense considering how they work.

The fix is to replace the pump assembly or ignore the symptom.

Sorry but that thread does not state that a new check valve was a problem and only 1 person posted inthat thread stating that an external CV didn't help and that his problem was in fact a FPR problem
Look at it this way. The fuel pump assy has a check valve in it already to prevent fuel from draining back into the tank. If it fails it's as if there is no check valve what so ever. Adding an external CV does no harm and simply puts a small component in the fuel line that replaces the the one that is normally in the tank.

If an external checkvalve causes some type of problem then an intenal to the pump checkvalve would do the exact same thing. They both do the same thing, allow fuel to flow in one direction only.

From the FSM:

Check Valve Operation: The pump outlet contains
a one-way check valve to prevent fuel flow back
into the tank and to maintain fuel supply line pressure
(engine warm) when pump is not operational. It
is also used to keep the fuel supply line full of gasoline
when pump is not operational.

Look Frank, I'm not going to argue any further about it. It's been proven to be a bad idea. If you want to give out bad advice, carry on- but that's all it is, a bad idea.

Not sure how many times you need to read this: "The BMW check valve will cause problems on Cherokees that do not have a return line to the fuel tank. " <--- Tim_MN

You keep stating that a check valve in a returnless application (97+) is a bad a idea but ignore the fact that that these systems are already equiped with a checkvalve, which in the OP's case is may not be functioning.

FWIW,
A single line system in an a Jeep means that any pressure above the setpoint of the FPR is immediately returned to the tank via the FPR.
Again from the FSM:

Fuel Pressure Regulator Operation: The pressure
regulator is a mechanical device that is not controlled
by engine vacuum or the Powertrain Control
Module (PCM).
The regulator is calibrated to maintain fuel system
operating pressure of approximately 339 kPa 6 34
kPa (49.2 psi 6 5 psi) at the fuel injectors. It contains
a diaphragm, calibrated springs and a fuel
return valve. The internal fuel filter is also part of
the assembly.
Fuel is supplied to the filter/regulator by the electric
fuel pump through an opening tube at the bottom
of filter/regulator (Fig. 3).
The regulator acts as a check valve to maintain
some fuel pressure when the engine is not operating.
This will help to start the engine. A second check
valve is located at the outlet end of the electric fuel
pump. Refer to Fuel Pump—Description and
Operation for more information. Also refer to
the Fuel Pressure Leak Down Test and the Fuel
Pump Pressure Tests.
If fuel pressure at the pressure regulator exceeds
approximately 49 psi, an internal diaphragm closes
and excess fuel is routed back into the tank through
the pressure regulator. A separate fuel return line is
not used.

I'll do ya one better. I've got a fuel pump from my 97 XJ that is the exact same as the one in the OP's 01 XJ. I'll box it up and send it too him for free if he installs a BMW checkvalve and has any ill affects from it at all.

Whatchagot?

so, if the a check valve is located in the FPR, which, is also the fuel filter, then no need to replace the fuel pump module.

As I said; Change the filter.

Fix the cause, not the symptom.

Fuel Filter 52100053 $49.95


The combination fuel filter and fuel pressure regulator is located on the top of fuel pump module


REMOVAL
The combination Fuel Filter/Fuel Pressure Regulator is located on the fuel pump module. The fuel pump module is located on top of fuel tank.

The filter/regulator may be removed without removing fuel pump module although fuel tank must be removed.

1. Remove fuel tank.
2. Clean area around filter/regulator.
3. Disconnect fuel line at filter/regulator. Refer to Quick-Connect Fittings for procedures.

Fig.3 Fuel Filter/Fuel Pressure Regulator


4. Remove retainer clamp from top of filter/regulator (Fig. 3). Clamp snaps to tabs on pump module. Discard old clamp.
5. Pry filter/regulator from top of pump module with 2 screwdrivers. Unit is snapped into module.

Fig.4 Fuel Filter/Fuel Pressure Regulator Gasket


6. Discard gasket below filter/regulator (Fig. 4).

Fig.5 Fuel Filter/Fuel Pressure Regulator O-Rings


7. Before discarding filter/regulator assembly, inspect assembly to verify that O-rings (Fig. 5) are intact. If the smallest of the two O-rings can not be found on bottom of filter/regulator, it may be necessary to remove it from the fuel inlet passage in fuel pump module.

INSTALLATION

1. Clean recessed area in pump module where filter/regulator is to be installed.
2. Obtain new filter/regulator (two new O-rings should already be installed)
3. Apply a small amount of clean engine oil to O-rings. Do not install O-rings separately into fuel pump module. They will be damaged when installing filter/regulator.
4. Install new gasket to top of fuel pump module.
5. Press new filter/regulator into top of pump module until it snaps into position (a positive click must be heard or felt).
6. The arrow (Fig. 3) molded into top of fuel pump module should be pointed towards front of vehicle (12 O'clock position).
7. Rotate filter/regulator until fuel supply tube (fitting) is pointed towards front of vehicle (12 O'clock position).
8. Install new retainer clamp (clamp snaps over top of filter/regulator and locks to flanges on pump module).
9. Connect fuel line at filter/regulator. Refer to Quick-Connect Fittings for procedures.
10. Install fuel tank.

The problem is the location of the check valve. If somebody throws one in upstream, it renders the factory installed ones irrelevant- therefore the pressure isn't controlled as it should be, possibly ending up with excessive fuel rail pressure and a rich condition.

Capiche?

:flipoff2:Actually, I'm with Frank on this one. The CV isn't going to affect pressure at all, no matter where it is installed.

I do disagree though, that adding one fixes the problem. Just fixes the symptom.

I would suggest if you can get a helper to hold the tank with you

step by step
good luck

Fuel tank may be drained by lowering fuel tank or if fuel pump is operating, by pumping fuel from fuel tank using a scan tool

Release fuel pressure from fuel system, if not previously done.
Disconnect negative battery cable.
Raise and support vehicle.
Remove fuel tank skid plate (if equipped).
Remove 4 fuel hose shield mounting bolts and remove fuel hose shield.
Disconnect filler and vent hoses from upper filler neck.
Remove tailpipe heat shield.
Support fuel tank with hydraulic jack.
Disconnect fuel supply line from fuel supply tube near front of fuel tank.
Disconnect EVAP canister vent line near front of fuel tank.
Disconnect fuel pump module electrical connector. Remove 2 fuel tank strap retaining nuts.
Position fuel tank straps away from fuel tank.

CAUTION:To prevent fuel loss through hoses, keep left side of fuel tank higher than right side.
DO NOT allow hose openings to drop lower than top of fuel tank.

If fuel tank was not previously drained, ensure fuel tank cap is installed to prevent spilling of any fuel. Slightly lower right side of fuel tank while feeding both fuel hoses through access hole in body.
Lower fuel tank from vehicle.
