I had my '06 CRD stall while driving through town one time. After checking a few things I noticed a soft fuel plunger. I have a lift pump so I knew something was wrong. Now, I had an intuition when I installed the pump that going through the floor in the cargo area would be wise in the long run...and it was! 10 minutes later I had the "hatch" opened up, electrical connector removed cleaned and re-installed and the vehicle up and running again. Mine was just a poor connection at the top of the tank, luckily. I would check that out if you can!
Also, I have the 2nd gen fuel head, a fairly fresh filter, Carter in-tank pump and I removed the quick-connects at the tank and my CRD STILL wouldn't pull enough pressure to run when the pump quit working. So the idea that these units are "pass-thru" may not exactly be true. I think the system is weak enough to begin with, that the extra strain from having to pull the fuel thru the pump in addition to the rest of the OEM system is enough to prevent function.
You might be onto something. I pulled the relay, and jumpered it to see if the pump was working. It ran. I re-installed the relay, and now the pump runs, so I might have a loose connection somewhere. Still no clue why the CEL is on, but no codes, unless the scanner that I have is not playing well with the CRD and isn't reading the code.
Check the connections where the relay plugs in and the wiring harness connections at the connector under the back seat and make sure all connections are good, tight, clean, and show no signs of overheating along with the fuel pump chassis ground that is under the back seat close to the wiring harness connector!
You may want to swap relays with one of the others next to it to rule out a relay issue, they are all basically the same relay and function the same....
