Oil pressure

Go rent a oil pressure tool,to check this,just because there is no clicking only means there is no damage to your engine yet,oil pump cheaper than engine,the pressure check will let you know for sure.

Okay if you change the sensor to a brand new one and it still shows 0 you need to have the oil pressure check to see what kind of pressure you have on the engine if it is no clicking noise in the engine then you've most likely got oil pressure IGM is real bad about the Clusters going bad if any gauge goes bad in that cluster panel you have to replace the whole cluster that could be your problem you could have a bad gauge as long as you hear no clicking noise you have a new sensor and you're full of oil you have a bad gauge and you've got to replace the cluster panel

You need to learn how to compose a SENTENCE. Me I but they side to what wrong truck oil starter fast light red then slower smell bad. ?
