If you have LOST Oil Pressure (Verified by the Gauge), then you could either have a clogged Oil Passages and no oil to move or worn Bearings or a Bad Oil Pump. DODGE has a HUGE ISSUE with SLUDGE. Adding a FLUSH (I actually use Diesel Fuel) in the Oil (2 quarts of Diesel for every 6 quarts of Oil) (this has worked for me for years and taught to me by a NASCAR OFFICIAL. Do not DRIVE the vehicle, but let it Idle for 20 Minutes while Monitoring Temperature. If the Oil Pressure is Truly ZERO, then Raise the RPM to get Oil Pressure UP to prevent any damage (lowest RPM to get Oil Pressure). After doing this for 20-30 minutes, Drain the Oil and change the Oil and Filter. Use a HIGHER OIL (20W-50) and see what happens. If the Oil Pressure goes up, then you probably have a clearance issue with your Main / Rod Bearings... If the Pressure goes down to Zero after it raises to Temp, then you need to change the Pump and Bearings.... Good Luck

Replacing the water pump on my 2004 5.9 cummins 1ton Dually was easy,Disconnect neg. batt. cables, drain coolant,released serpentine belt tensioner with 1/2" drive ratchet and while in released position slipped belt from ac compressor,removed two bolts that held alt. to brackets, slipped alt. to one side then removed upper alt. brkt., removed two bolts on water pump, made sure mounting surface of block was clean and took new water pump put a small amt. of rtv sealant all around groove that rubber seals goes in,install rubber seal, "be sure and wipe off excess sealant then re-install water pump tightening carefully,reinstall alt. upper brkt., then alt. put belt back in correct position but be sure and leave it off of ac pulley so you can reinstall it on ac when you are underneath the eng. area while releasing tension on belt tensioner. Fill with proper coolant type till you have rad. full. Reinstall cables, start eng and with cap off you will have to add coolant as eng. warms up till it has air out of system. Once rad. is full install cap then refill coolant recovery bottle to full level, Keep and eye on it for leaks for a couple of days and "Happy Driving" Don't think I left anything out :)

Sounds like your TPS (Throttle Position Sensor), if you have changed that it could be VSS (Vehicle Speed Sensor)
