Just wondering if anyone else may have experienced this. I changed out the oil and filter and both fuel filters yesterday. Put everything back together, and now the truck won't start. I get the "wrench" and "oil pressure" warnings on the dash display. I've purged the air from the fuel lines, checked the filters for proper install.... no luck. I even tried disconnecting the batteries to see if that might clear the fault. I got it to fire up for about 3-5 seconds, then it will shut down. Any help would be greatly appreciated.

Cycle the key to ON several times. You should hear the fuel pump run and then shut off. Works on the 6.0.
