Your story is very pathetic. Why would he remove your ECU?? Get back the ecu. And every thing he had removed from the car. Your problem might not even be your ecu. Call this number. 08165520837 or 08156087872. Bb pin 7BE1C522. You can get help

Change the Crankshaft Position Sensor and your nightmare is over.

What did you do before it started and what type of key are you using.

Is the key light coming on?

Try starting with the spare key.

GAZZUZZ:

Grand Cherokee stalling issues has nothing to do with key.

chucky234: Grand Cherokee stalling issues has nothing to do with key.

Young man, if the key is elecronic programmable chip type, it could bring a form of stalling even after starting due to the security immobilizer not accessing the code.

By the way, lately, you've been replying me in threads in a manner that isn't nice, what's your beef with me?

Try to observe the security light when the car is off. Does it come on for a 2001 grand cherokee it should be a key with a transponder chip. First get back your brain box and get that car scanned. You need to run a scan on the immobiliser though if it has been tampered with you might be having issues communicating

chucky234: Change the Crankshaft Position Sensor and your nightmare is over.

Would a bad CPS even allow the engine to start at all?

I've always thought the car will never start since the timing is completely off.

You are right oh however Bad cam sensor wont make it star but bad crank sensor would,one is one is on top the other under

Here's the thing, if either (Camshaft sensor or Crankshaft sensor) are faulty to the point that they will turn off the engine after starting then I don't think the engine will start in the first instance since BOTH have to be in sync (timed properly) for the engine to start at all.

Also either should have been setting off a CEL sporadically if they are faulty.

Just conjectuirng since I don't have enough data to call this one.

I don't think the 02 Cherokee is sophisticated enough to have the security key thing but I don't recognize Jeep products so I don't know intricate details about them.

your car can Scan itself, its has an On-board OBD11 diagnostic
follow this procedure,
put ur keys in ignition,turn to the point jst b4 it cranks(Ignition), remember dnt let it crank, then return it to the nutral positinion(Off) each time it bleeps, do this 3 times and at the third time leave the keys at the Ignition positionl position, thats the position that allows you to see teh battery light, check engine light infact all teh light on ur dashboard, at that last point look at the dash just where the Miealge is, the fault codes will display very fast, have a pen n paper in hand and write them down quickly,It works for all Jeeps.

JGC stalling issue is a curse to the 1996 -04 GCL, I used to own the 2000 GC 4.7L V8 model and had same stalling issue and was spending money changing parts until I stumble on a US JGC forum where I discovered the solution.
The next day I managed the car from Ojo barracks to a Mech workshop along 2nd Avenue in Festac where I had them changed the CPS, that was the end of my sleepless nights.

Got not no beef with you bro, my problem lies with your excessive overhyping of the RX. by the way how dare you refers to an oldman like me as a young, if I slap you ehn.

Scan will not detect the fault, even dealershops in the US have no answer to the problem.

So the CPS was shifting around? Do you happen to have pictures?

Bro Scan would, even the car Scans itself if you know how,I just explained it up there.I have a Jeep Liberty.

@ Bolded, let's give credence to whom its due, let's call a spade a spade. RX fares better in terms of sales, reliability, build quality, comfort and others when compared to its rival Range Rover Freelander which its meant to compete with. I can't buy an $80,000 vehicle and still visit mechanic as if that's where I live I should drive such with peace of mind and a lowly $38,000 RX330 gives that. So, if we are gonna compare a RR autobiography with a LX460 then we'll say the game is fair yet the LX640 still does better than the range bar the perceived comfort and class status.
I'm still a young man, slap me and I'd break ya face!

Intermitent faults and what the OP described here are not the same thing, I used to have a dodge caravan and when ever it became hot the car misfired and yes I had to change the crank shaft position sensor at the end of the day, it solved my problem "but I had to scan when I had the misfire b4 I knew what was causing the problem" the OP'S car goes off after 10secs that "is not a Crankshaft position sensor problem" the immobilizer is shutting off power to the injectors or coils or both (don't know how jeeps immobilizers work) but clearly NOT a CKP problem OP please scan your vehicle and also take a pic of your dash board (instrument panel) when you are cranking also take a pic of your vehicle car keys. Don't throw parts at a problem you just end up wasting money.

my car was having this same issue. Its either u change ur cps or u reprogram the ignition key, its like ur car immobilizer is faulty. My car does not have cps so i have to reprogram d ignition key, there is a chip inside d kkey dat is failing. Try it

Since you sold off that your QX4 to buy RX330 I no dey hear word again, I go soon fall your hand.

CityNG:

I dont have the pics as I sold off the car in 2009 due the 4.7L V8 engine excessive fuel consumption, not friendly with Lagos traffic jams.

Based on the op's car problem. There is a mis communication between the key, immobiliser and his Ecu. So let him get the EcU first and scan the immobiliser of his ride. Sure he would get fault codes there. If it were to be a ckp problem the car won't and would never start. But in his case car starts and almost immediately shuts down. post pix of your instrument cluster and let me know exactly on what to comment on.

The car will start and drive for few minutes before stalling if the CPS is faulty.

A faulty ckp causes misfire although depending on how the cars elctronics was designed. Some cars cmps if faulty would not start while some would. But from the op's explanation this not a ckp problem
