97 oil pressure sender/switch confusion
Both my 90 and 93 have a relationship between oil pressure and fuel supply. Generally, if oil pressure is low, the fuel pump will be truned off. For the life of me I can not find any reference to the "switch" part of the oil pressure sender/switch in the 97 manual. The connector view shows 4 terminals but I can only see two of them being used in a couple diagrams. All of which relate to the sender part and run the oil pressure gauge.
I could not find any input to the PCM either. Since the PCM controls the fuel pump module in L67 equipped vehicles I figured this would be a good way to shut the fuel pump down in the event of low oil pressure.
Can someone clear the smoke?
