I’ll ask them again when the ECM comes in. Supposedly both issues I’ve had where it called for the pump replacement was in end of January early February up here in Michigan. They said it was safe to drive and I went to Nashville this past weekend. Warmer weather and it cleared the CEL on its own. Coincidence maybe. Took it in to have the pump replaced the other day when part arrived. Told them it cleared up so he went in and manually opened the pump gate but couldn’t get flow to turbo so they think it’s an ECM and maybe tied to the glow plug outside parameters issue. I’d really like this motor if it didn’t have all the junk attached to it.

Mine has thrown an intermittent glow plug value outside parameter code but seems to clear and go away. Dealership here thinks a faulty ECM might be causing both issues. I am also getting poor fuel mileage and excessive DEF usage when the CEL is on.

Dealership thinks it’s the ECM.

Dealership just called. Apparently from some diagnostic testing they don’t think it’s the pump that is the issue but now believe it’s a faulty ECM that’s been the issue all along…and guess what else…the ECM is on back order!

I’ll ask when I pick it up. Its in the shop now.

65k miles on my 3L diesel. Truck goes in next week for a second electric pump replacement. Had the first one around 30k miles. Truck doesn't have near the power towing and used a tank of DEF in 525 miles.
