A PO251 is showing up as an injector pump issue on a diesal. I don't think you have the duramax in your vehicle. Can you tell me if you checked for fuel and spark to the engine?

No we don't have the Duramax in the van. We can hear the fuel pump running and smell the fuel. It is 11pm now, I will have my husband check on the fuel and spark in the morning. We have recently replaced the glow plugs and the glow plug controller.

I need to confirm something. If you have glow plugs, then it is a diesel. Please let me know.

Yes, it is a diesel, but not the Dutamx. It is a 6.5.
