P1263 comes up as Glow Plug #2. I assume that is a short in the circuit which means bad glow plug. Done. Not the problem. Next step is the Wiring Harness which is not available. Back Order till further notice at Chrysler. ANSWER.com suggested I try the Harness from TDi Jetta 04-05. I bought one on eBay for $68. Any thoughts on this?

I sold this CRD with the experimental harness and a free code reader/eraser

Why do you need to replace the harness for just a failed glow plug? You may run into issues using a glow plug wire harness from a different application. The wire diameter, connectors and wire length are all designed into the ECM control strategy based on a calibrated resistance and voltage drop across the circuit. If this known value changes it may effect the voltage seen at the glow plug when they are energized.

Did you change out all the glow plugs to the new ones or test the one in place to see that it is OK? Did you just replace that one GP with an old style ceramic plug and not the newer metal type? Also some wiring harnesses were put in backward and that needs to be checked. Folks here know more abut these issues than I do but I have seen posts about them before.

Several CRD's had the harnesses installed backwards - the computer reads #2 but it could be # 3 - the test is to measure resistance.

at the 4:1 connector - measure plug resistance - good is ~ 1-2 ohms (many multimeters have problems reading that low.) bad is commonly 200+.

All four glow plugs were changed with the hard to find ceramic bosch brand (new) and the DSG installers charged $350 to put them in. The code still came up. I'll be checking the impedance next. I've got to get the digital readout type reader. The $10 one is not accurate.
When bench testing the plug...is it the extreme nipple tip (hot)to make contact with the exteme opposite end? Pardon?
Also the ask.com people suggested that the harness from 04-06 tdi jetta might work.
I think if it's not the plugs, it could be the harness short of a missconnection theory.
Can the impedance be checked at the fuse box? If so which fuse. It is vague.
One more thing, a fellow CRDer from Alberta is having the same code and he had all the plugs replaced. The dealer broke one and is holding the customer responsible. that's not nice. Now the head has to come off and that's $2,000.
The glow plug kit he received off the shelf at a Red Deer Dealer included the wiring harness. Wow.
When trying to order a wiring harness from Chrysler, they want you to buy the entire engine harness as well for astrological price of $1500. and it's on back order till further notice.

I have the same code and bought the kit part number 68090424aa which includes new metal plugs and GCU, now the dilema is that the ECM has to be updated as the metal plugs are 5v instead of 7v. I'm going to replace the plugs and GCU this weekend and take it to the dealer on tuesday to see if the can do the GCU/ECM update only. I'll keep you guys posted to what happen.

If you install the new style plugs...

LEAVE THE CONNECTOR UNPLUGGED UNTIL YOU GET THE COMPUTER FLASH!!!!!!!!!!
LEAVE THE CONNECTOR UNPLUGGED UNTIL YOU GET THE COMPUTER FLASH!!!!!!!!!!
LEAVE THE CONNECTOR UNPLUGGED UNTIL YOU GET THE COMPUTER FLASH!!!!!!!!!!
LEAVE THE CONNECTOR UNPLUGGED UNTIL YOU GET THE COMPUTER FLASH!!!!!!!!!!

Sorry for repeating myself like that, but if you even power the car once with them connected, you risk killing all those shiny new glowplugs, and possibly your engine if they shatter into the cylinders.

Thnx geordi and papadingo for your advice. I will leave the 4 wire connector for the plugs disconnected until I get the ecm updated. still I have a doubt. will my crd start without the GPs????
thnx again
PS: I test the 4 plugs and all but #2 read 3homs the odd one is 243homs so I guess my ecm code is justified (p1263)

Unless you are located in an arctic environment... Your CRD WILL start without the plugs. The need for the glowplugs is marginal at best when the temperatures are over 40 degrees, and everywhere I know of in the USA is having summer temps right now.

Post subject:  Re: CRD Engine Code P1263
great, ill get those new plugs install tomorrow along with the GCU and i'll leave the 4 wire connector leading to the GPs unplug intill I get the update done by the dealer. Here in Houston we are on the 90s already (70s in the morning) so I shouldn't have any trouble.
one more question, my CRD was fix by TBS with the TC and tanny pump but somehow the ECU flash wasn't done, so, will the dealer do the f37 flash if I take it for the GPs update? :dizzy:
thnx again

I think my engine takes a little longer to start with the new glow plugs and flash in the morning. Now I turn the key to on and wait till the airbag lights go out and starts in a snap. WTH did Jeep do to us??

that sounds like a true fact, but I wasnt able to find the 7v GPs anywhere, and at this point even if I find them I got the feeling that if I need another one later it will be impossible to find. you've said it, WTH did jeep do to us??? why didn't they just came with 7v metal plugs!!!
:furious:

I had my GP upgraded, was getting a code for two of them. I have the old GPs and two of them should be good. May be of use to someone who just wants to change out one of the old ceramic type and get a bit more life out of the current system. Free for the cost shipping.

The 05 Liberty CRD was sold for $13k which is a deal in this market with 84k miles. I had to throw in the glow plug harness and reader eraser to keep the customer happy.
I am now considering that Alberta CRD with the P1263 code and the dealer that broke the glow plug, I'm not exactly sure how, and they charged the customer to R&R the head, etc.?
That guy.
I drove this troubled jeep crd and there is engine vibration throughout the interior. Like the block or the exhaust is rubbing against a frame somewhere. Any ideas?
I haven't bought it yet. Going into the Safety Certification garage tomorrow to see what they say about the rebuild status. This CRD was in a LH front corner accident. No engine light. This one had P1263 and the dealer changed the GPs and light is out.
The jeep showed up last night and the list goes on... headliner damage, new front bumper required, hail damage, perforated rust in drivers door...
I didn't buy this one.
Canadian Black Book wholesale is $7900 is another reason to walk away from this deal.
It gets tiring to deal with salvage rebuilt acquisitions too often.

right front accident, look to replace the right front engine mount. Its not that hard to change, and if the rubber is shot in it, the engine can easily vibrate through the body.

If the accident was LH corner same motor mount rule is true?

Oops, I just re-read your description of the vehicle. I was obviously blind before, and somehow saw RH when it quite clearly is LH.

Yea, should be the same thing tho. The engine mounts would be the most likely suspect, as they have a history of being dodgy anyway with our heavy motor. I had a Taurus years ago that got in a front hit (FWD mounted engine) and the front engine mount tore from the impact. Buzzed like crazy, but still drove OK. An easy way to diagnose an engine mount is to have someone sit in the driver's seat and move it through the gears, but NOT let the vehicle move.

Watch the engine as the gears engage, park to reverse... Park again and let it slack, Park to Drive... It should shift maybe a half-inch or so from at-rest. Much more than that... The mount is gone. The direction it moves more can help in diagnosis... But maybe not that much.

Front motor mounts were installed, Chrysler part, didn't help. Anybody want a front pair of motor mouts from an 05 CRD?
What did work a little was prying the spring steel transmission bar mount away. It was rubbing.
