2001 Dodge Ram 2500 Q&A
2001 Dodge Ram 2500 Question: After engine warms up oil pressure drops to 0 at idle.
Check your oil level.It sounds like the oil pump is going bad. - Pay it forward
I had a 1995 DODGE RAM 1500 with a 318 c.i.d. engine that did something similar,If oil level is ok. , and there is no knocking or tapping, Try another oil press. switch .There not that expensive but they are a bit of a pain to get to......back around the distributor.If memory serves me right i think you may need a special socket to remove the switch. Good luck - T.Starr
