Our 2009 MRU with and MP7, we pressure tested the cooling system and took off the return lines on the fuel tank and fluid (coolant/fuel) was coming out of the return lines. Is this normal, or would it be a sign of bad injector cups? Or could it be something else. Where else should I look? I have new sets of cups and O-rings, but if I don't have to use them, I will send them back.

I have a 2009 MRU, I'm having problems with a code that comes up (MID 128 Engine ECU, SID 232 5 volt supply, FMI 4) Inactive #19.
The ecm and wiring harness has been changed, and we are still having the same issue with the same code.
The truck will run fine for a day, the the CEL comes on and it goes in Derate. We have taking it to dealers and 3 party shops with no luck.
Anyone have any suggestions?????
