Post subject:  Jeep liberty CRD won't start!!!! HELP!
I need help figuring out what's the issue with my 2005 liberty CRD.
I recently bought it as a project car, but the person I bought it from didn't know what was the issue. It use to turn when I went to check it out and drove it back for 120 miles with no issues, it ran smooth other then it use to take a bit longer to start then any other car. When I got back home I tried to turned it back on and it wouldn't turn on, I used a bit of starting fluid and I got it to turn on it ran good no issues drove another 40 miles without a problem, but if I turn it off I can't get it to start normally.
The engine light was on with codes P0093, P1265,P1267.
I realized that P1265 and P1267 had something to do with glow plugs 3 and 4, so I went ahead and replace them hoping it will fix the issue, but no luck, it won't start.

Any advice from anyone ?
Thanks

This sounds like an air-in-fuel issue to me. Open the hood, find the fuel filter head on the driver side near the windshield, pump the primer on it until it gets firm then open the small bleeder on the side of it. You'll probably get a sputter of air and some fuel spray. Continue to do this until you get nothing but solid fuel and try to start it again. Two notes: be gentle on the bleeder screw as it strips out the threads very easily if you try to torque it too much. Use a rag to catch any excess fuel that comes out of the bleeder so it doesn't drip all over the engine and electronics below it.

Report back what you find. If this temporarily fixes the problem you have a bad fuel filter head. The short term solution is to keep bleeding the filter head when you have trouble. The intermediate solution is to replace the fuel filter head. The final solution is to install an in-tank lift pump to put the whole fuel system under light pressure to prevent air ingress. There is a lot of information on this website on how to do that. Just let us know when you get that far.

I just bleed the primer and a lot of air came out, the first one was just pure air and it took about 5 times in order to get solid fuel, but no luck on starting the engine, could that mean that it is actually an air in the fuel issue for the amount of air I got out of the bleeder?

The P0093 code is related to fuel rail pressure so could be air in the system.

Download the 2005 Jeep Service Manual here to see what to do about it. The 2006 Services manual is actually easier to use as there is a DTC index at the bottom of the Index page which tells you which page to go to for each error code.

One thing mentioned in the manuals is that a missing ASD signal can cause this code.

Try swapping over the ASD Relay with an identical one next to it in the fuse/relay box under the hood.

You can also remove the ASD relay, identify female pins 30 and 87 inside the empty relay socket and jumper those two pins together and see if it starts.

Is the red LED on the left of the cluster ON all the time or flashing at you? It should light for a few seconds with ignition ON then go out if the SKIS anti-theft system is working OK. :?

I haven't checked to see if the led light lights up, but one thing I forgot to mention is that the previous owner told me he thought it had something to do with the alternator not charging the battery, because he had to fully charge the battery to get it to turn on, but when I was there I checked the voltage at the battery while it was on and it was reading 14.3v, so I assumed that the alternator wasn't the problem. I turned the car off and the battery red 12.5v
But after I got back home after the two hour drive I checked the battery once again when it decided not to turn on and it red 12.2v , but I don't really understand why if the alternator seems to be working and reading 14.3v at the battery.
I tried to jump start it but I couldn't , so I discarted the issue being not enough charge, I haven't tried changing it back up but could this mean I'm wrong and possibly be a battery issue?

These vehicles definitely DO NOT like low voltage!
If the voltage is dropping below ~9v during starter engagement, it's highly possible it could keep the engine from starting. :banghead:
You may want to give the battery a good charge or try a new fully charged battery and monitor voltage at the battery while trying to start the engine. :idea:

X2. Most modern vehicles electronics do not like low voltage. Too far below 12 volts and the engine computer will loose power under the load.

Just to clear up something....does the engine turn over but not Fire?

If it does turn over the battery voltage at rest should be about 12.4 volts.
The voltage while turning over should not drop below about 9.5 volts.
The voltage while running should be about 13.4 volts.

Very important is to have clean and tight battery terminals, clean and tight negative lead going to chassis on both ends and likewise with the engine grounding strap going from engine to chassis must be clean and tight both ends.

Connections to Starter Motor/Solenoid on firmly.

If the above is not true then the ECM/TCM BCM etc. could receive a low voltage which they do not like! :shock:

Last night I fully charged the battery from 12.0v to 12.6v, but it didn't turn on, the engine turns but it won't fire up, so I'm leaning more towards a fuel issue.
After going through the manual , thanks for posting the manual link, I found the code section, "P0093 - FUEL RAIL PRESSURE MALFUNCTION POSITIVE PRESSURE DEVIATION"
So could it could be something to do with the fuel pressure solenoid or the sensor?
I found a working used fuel rail with sensor and solenoid online, I'm thinking of buying it, but before that is does anyone knows a was to test these Two fuel rail components?

I had that code.
Except my scanner said it was a p0193. But same description.
After replacing the fuel rail pressure sensor and the fuel quantity solenoid on the CP3, I discovered that the problem was a loose connection at the pressure sensor.
I spliced in a new connector and all was better again.

Quick update regarding the issue on my Jeep that won't start.
After receiving the fuel rail with the sensor and install them the issue persisted and is wouldn't fire up.
After doing some more research I found a post regarding the same code P0093 and describing the same issue, that the car won't start, the person suggested on using a fuel injector cap tool used on 5.9L Cummins engines to test faulty fuel injectors.
I went ahead to order this tool and last nigh I proceeded to test it out and it WORKED!
before the test with the cap off tool the fuel rail pressure was around 2100psi while cranking
When I placed the cap on the 3rd injector the fuel pressure increased to around 3800psi and the Jeep fire right up!
So I concluded that I have a Faulty Fuel injector.

My next Questions Will be,
Is there a place where I can send my injectors in to get the rebuild at an affordable price?
If not
Can I install a new injector without having to program it into the ECU?
If I can't can I Program it myself? Or can any diesel shops do this?

Any Bosch "certified" Injector repair service should be able to perform a rebuild. Certainly ask plenty of questions first.

This is one that has been mentioned many times on LOST; there may be others?

This is the cheapest place I have found. They are in the UK. You will have to send your injectors to them as they will not have any cores to swap out for yours in the Uk. I believe it was $572 for all four injectors remanufactured. You will have to add shipping on top of that. Seems like that was around hundred bucks for three day. You will have to call them as you will not find Jeep Liberty injectors on their website. Get yourself a calling card...

Each injector has a unique number on it so make sure you put the injectors back in their original position. :wink:

I believe I was the Person that suggested capping injectors one at a time. To identify the faulty one, most likely you will only need to replace only one as far as injector calibration codes, you just need to find somebody with DRBIII tool. For now with the new injector installed you can drive it for now it wont hurt engine.
