your oil pump could have gone bad or you have a restriction in the flow like a clogged oil filter. needless to say if it is knocking it may have caused major dammage
195 to 210 is normal
Waht is the answer?
Definitely! I had this problem diagnosed and found that the gas gauge is fine, but the internal float sticks and this is a common problem. Obviously the "Check Engine Soon" comes on because of this and the gas gauge is almost always incorrect.
If it is not working you have no oil pressure and the oil light will come on or the oil pressure gauge will drop to 0. You will also hear engine noise, as in, pecking, or knocking. Engine will also overheat very quickly.
NO. it has NOTHING to do with the engine starting. It works the fuel gauge in the dash only.
It is on the drivers side head, Back by the last spark plug by the cab.
Check the sending unit between the left first 2 spark plugs. Ground the wire with key on (gauge should peg full hot). If it does change the sending unit.
Buy a new Speedometer cluster. The external Temp gauge is extremely rare
check the plug at the tank to see if its conected good
were is the fuse for speed gauge
The fuel gauge on a 1985 Chevy Silverado will read full all the time if the sending unit is defective or the wire has come loose. When the tank is full, the sending unit normally shuts off which cause the gauge to read full.
Check engine light : Gauge cluster without tachometer ( under the engine oil pressure gauge ) Gauge cluster with tachometer ( just to the left of the battery voltage gauge )
