More Problems More Money: P0093 and P1263

HugeKJ05 · **Posted:** Mon Jun 09, 2008 1:03 pm

So I just replaced the #2 glow plug about two weeks ago. I was expecting the MIL light to go off the next moring after hooking the battery back up, but over course it didn't. It was not blinking so I just decided to drive it since I really didn't have too much money to play with to continue to screw with it. So now May has come and gone and I am past due for an inspection. I just took the jeep to Autozone to have the ecu scanned to figure what else is wrong with it and they came up with : P0093 twice (Fuel Leak LARGE) and P1263. Seems like the P1263 could be the #3 cyl glow plug from what I have read searching here on the forums. P0093 seems like it could be a slew of things though.

Has anyone had the P0093 code and what did you have to do in order to fix it?

So far I have read that it could be:
1. water
2. crappy fuel filter (Where can I buy another other than DC?)
3. Bad sensors on fuel rail
4. Bad injector

So who has gone through this BS and what was the fix and cost?

Thanks in advance,

Jason

NAPA has fuel filters.

0093 is air in fuel. Throw a cheap fuel pump on it and it will never plague you again.

IIRC someone posted a few years back about the glow plugs being miss wired. So when it threw a code for #2 being bad, it could have been plugged into the wrong spot on the harness so 2 could be 3 or something along those lines.

I have owned the CRD for a while now but have not spent much time learning about it until recently. Can you fill me in on what brand and where to buy a fuel pump.

I ordered a fuel filter from Napa today and will probly order another glow plug from moparpartsamerica.com see how they are cheaper than what summit racing carries them for. I will have to see who we have for sponsors on this forum who may carry these parts.

See the thread titled "it's 10 pm, where's your lit pump?" You can get a dodge cummins pump for $149 where your getting your glow plug. It fits in the tank and then the total fuel system is under low pressure instead of a vacuum :wink:

You can get a faucet at NAPA and it's simple to put on up by the filter but if your vacuum leak is in the rear by the fuel tank you could still get air. With a lift pump you'll notice much improved response :lol:

It sounds like all those who have done the in-tank fuel pump are very happy with them. Their down side is that they may be a little harder to install and are more expensive than some of the inline pumps. I have an airtex shuttle pump for a duramax on my frame rail and I have had no trouble out of it for almost a year now, but if it fails I will probably do an in-tank instalation of the Cummins lift pump.

I am reading throught the "10pm" threads and there is a great amount of info to absorb. Seeing that there are 33 pages to one of the threads, I am not entirely through reading it yet. My biggest question as of right now is: What is the absolute best in-tank pump to switch to and what model/year cummins did it come from? I would also like to do the filter swap at the same time.

Maybe a plain parts list would help. I will keep reading on, I am sure I will find the answers to my questions. This just sucks because now I need to do this work done asap seeing that I am past my inspection date and it is just a matter of time before I get pulled over. May was the month from hell for my KJ, seems like everything just went wrong one thing after another, lol. Not so good for my bank account.

We've been getting the pump for a 06 Dodge 3500 diesel. Two tank sizes are listed. They seem to be the same pump though?? Don't give them your vin, it will delay the order :lol:

It turns out you may want to switch the metal float arms to maintain correct guage reading. Several people who have gotten the whole harness assemblies are supplying some of us with pins and or wires so a new harness is not needed. If your at home with a soldering iron and heat shrink it's a good option. Also some harnesses are on backorder. GMCTD has posted the part numbers a couple of times in the thread :wink:

It appears the 06 gasser harness need a lot of pins changed and many/most have just added the wires. I don't think there's an aftermarket in tank pump for the dodge.

Will the 3500 diesel harness plus right into the existing KJ CRD harness? If so, I may just grab it to save some time.

I just did a quick search on mopar parts, the fuel pump seems fairly priced but I was not able to find the harness. What would be the tech name for the harness to see how much it is?

So for right now, I would need to:
1. swap fuel pumps
2. work some wiring at the fuel pump
3. ...

Some else mentioned replacing a few lines in the back?

Filter assembly swap?
Faucet?

NO. The CRD's fuel guage connector plugs right into the Cummins pump and guage assemblie. It just needs a ground and plus 12 volt pins (pump wires)
Then under the left backseat is a connector that has the 12 volt pump wire already in it that comes from the power distribution box up front under the hood. Relay and fuse are even in there already. Add a pin and wire to the rearward connector under the seat. The ground wire is screwed to a cross brace that already is drilled. Run both wires rearward to the connection on top of the pump. They can easily be put into the flex loom without taking the harness out :wink:

So for right now, I would need to:
1. swap fuel pumps
2. work some wiring at the fuel pump
3. ...

Time to bump this as I am doing all the work now. I checked my glow plugs all of them look good. I may just replace the on that the ecu says is bad just so I dont have to go back in and do it again. I posted some pics in another thread I have going called "oil in charge pipes" or something along that line. Everything looks really crappy in the intake system so I want to go through an clean everything but its going to be a huge ordeal. I am already in deep so I am going to keep going.

Here are the pics from the other thread.

Elbow off the intake manifold.

Hungry anyone? This is nothing compared to what is still in there.

As she sits now

Looks like dissabling the EGR is in order. If I plugged the back of the exhaust manifold, will there be any adverse affects? Again, this motor and diesels in general are all new to me. The back of the exhaust manifold has a tube that connects to the other side of the block and then another tube come off that section and into the elbow the throttle body bolts to and make the mess you see above. I would just rather dissable the system. Any thoughts?

oops, double post

SEGR threads cover disabling the EGR system. You can block it, but without fooling the computer-- you will go straight into limp mode. The SEGR fools the computer and it never opens the EGR valve, making blocking optional it optional as long as the EGR valve is working ok. Simply doing the "ORM (off road mod)", which is unplugging the MAF sensor-- greatly reduces the EGR operation, both for off road usage only-- of course. Down side is check engine light becomes your ever present friend.

Well the check engine light has been my ever present friend and I need to fix that so I can get the jeep inspected as I can not drive it right now because of that. Is there any way I can still buy a completely assembled SEGR. I am not an eletronics guy to say the least. Since I do have everything apart since it all needs to be cleaned, buying or making a SEGR is a must first step and then I think I will block the end of the exhaust manifold to take care for the rest. I still can believe the amount of junk in there. No wonder the thing was running like a dog.

on the assembled SEGR - check with UFO
