Question about 2000 Jeep Grand Cherokee

1 Answer

The jeep stalled and wouldn't restart determined the fuel pump had gone out because there was no fuel present at the pressure test port replaced fuel pump the jeep ran great for about 15 minutes and stalled again and wouldn't restart we have checked the fuses the relays even the cannon plug at the tank to make sure we didn't screw up ..everything checks will the throttle positon sensor cause this particular problem?

    TPS will not cause that. I would check the crank position sensor and the asd relay to make sure both are good. By checking, do you mean that you looked at the relay and plug or have you established that both the ground and power are present at the harness plug and at the relay and also that there is continuity between the relay and the harness plug at the pump?

    are you sure there is enough gas in it?

  • data_huntr May 29, 2010

    we checked for damage or corrosion its clean and free of damage at the cannon plug, when it stalled i bypassed the fuel pump using a pressureized fuel tank and it runs ok enough to drive it back home the self diagnostic in the vehicle runs through and says done no errors
    relay was replaced no blown fuses what about fuel pressure regulator? or what ever controls the fuel pumps cycle, and to answer Doug yes it has a half tank of gas

Have you checked for spark and or injector pulse, you will need to use the spark tester for ignition and a noid lite for the injector pulse

2004 jeep GC stalls out after running awhile.Changed fuel pump still have stalling problem


which engine.????

why guess?

ill assume the full 60k mile tune up was done.

you picked the most hard fix of all and guessed wrong, wow.

if the engine is good, compression great.

there are only 3 causes of stalls, in pure Physics. bla bla....

in reality parts wise over 50,, guessing is not going to work.



what does worK? diagnosis, want to test or guess.?

on all jeeps we have this funny thing called ASD,

but first, i must ask a key question. can your right FOOT save the stall if it gets happy footed , at the stall point?????? bid deal important that.?????



ill pretend NO, for THAT.( post the facts ,im showing real tests , and real results here) yours will vary.....



lost spark?, is the cause, not fuel.? (efi cuts fuel for loss of spark in the ECU LOGIC, so spark is first ,if hot compression is not dropping)

but id check the ASD next or drive with a scan tool attached (any) and see the PCM/ECU tell you why it stalled ! , it will 1/2 the time.



in addition to that, the ASD relay must be monitored, (scan tool will do same)

if the RELAY DROPS? then we know why , see?

see the 8 ways to DROP and ASD here !

http://www.fixkick.com/Jeeps/ASD.html



see those, if they drop , each tells you why.

if the ASD did not drop, then it starved for fuel. (compression good)

Examples more./......

say , you get no DTC errors (scanned), and ASD holds fast,. at stall?

more examples::::

does it starve for fuel with gas cap loose , then wrong cap

its missing the vacuum breaker inside, a 5 buck fix. and kids can change it. or worse?, caused it.LOL

More examples:

we use a fuel pressure guage at the fuel rail (TOOLS RULE)

if the pressure drops, at stall , and not ASD drop.?

then you have bad wiring from the fuel pump relay to the tank pump.

or a bad relay. the volt meter will prove that.. easy.

very common on all EFI cars, bad wiring, and 10x that in the salt belts.

google salt belt, or wiki it.



this is how all 1993 jeep to present run. ASD is first to watch , hint.!

ASD dont drop:

if fuel pressure is good?, then wrong tree to bark up.

if fuel pressure was low, check voltage to pump cranking

must be 12v, or 11, if cold and battery weak

less voltage , is BAD. fix bad. (clean connections.)



only takes 3 tools.



  1. volt meter


  2. compression gauge.


  3. fuel pressure gauge.


a vacuum gauge part of a hand vacuum pump is nice.

most fail paths can be found with minimal tools. about 60 bucks worth. in any DIY shop.



and sorry , you cant fix modern cars with out a scan tool

buy, rent or barrow one. they are everywhere.



all answers, USA and no engine stated so 100% generic answers.!

not flex fuel opted, not CNG engines.



and P0181 not set, pump dead, error fuel pump.



see this page.

here,

click WJ

click Emission

click on diagnosis section see all those DTCs, get any????

no P0215?

loss of cmp , loss of CKP

gross missfiring? codes.

endless really, scan it. at stall , scan it.

1995 jeep cherokee stalls regularly and then restarts. problem persists. any answer?


Souhds like you may have a weal fuel pump.Check your fuel pressure if not within the specs replace fuel filter first and if pressure is still low then replace the fuel pump.Your fuel pressure should be 31-39 psi with key on and engine off.

I have a 1997 Jeep Grand Cherokee Laredo, 6 cyl. It will stall while I am driving, and may restart right away or may not restart for 20 minutes. I keep hearing this is a common problem for these Jeeps...


check fuel pressure regulator.....Fuel on one side of diaphrag, and vacuum pressure on other if there is fuel on the vacuum side then diaphragm is leaking...causing ecu to think there is plenty of pressure and holds back the signal to turn on fuel pump....

Hard to start in the morning. Also stalls


This sounds like a fuel pump check valve problem, if the fuel is not kept in the filter and lines by the check valve it drains back into the fuel tank and causes the kind of problems you are having, you can check this by hooking up a fuel pressure guage at the test port on the fuel manifold that supplies fuel to the injectors, run the engine and shut it down, note the fuel pressure at shut down (with the test guage hooked up), walk away for an hour, come back and check the pressure, it should not have dropped more than 5 PSI You can buy a universal fuel injection pressure tester for about $25.00, cheaper than having a shop run the test. If the pressure drops you found the problem, bad news is the check valve is in the pump, the pump is in the gas tank.

Engine stall


The fuel injectors may need to be cleaned. Also the issue could be the fuel pump or fuel pressure regulator. You can test this by renting a fuel pressure guage from the auto store and hooking it up to the fuel rail on your engine. The port you hook it to is called a schrader valve and looks similar to a tire stem valve. If the pressure is low the problem could be either the fuel pressure regulator or the fuel pump. Good luck and if you found this solution helpful please rate it.

Thanks - Tech101
