Hello, so when you say you replaced with a new one do you mean new from dealer or just new as in replaced like from a junk yard or used car?
also when you start the van do all the gauges do the test sweep ?
ok, the gauges should all sweep from the bottom reading to the top reading when the key is turned on, so that is odd, but lets see what we can do to make sure the cluster is not the issue, do you know how to test wiring by checking volts, ohms, continuity?
ok good deal, so we need to access the oil pressure sensor and connector on the engine we will start with that one there.
what engine is in your model?
ok thanks, ***** ***** have a 3 pin oil pressure sensor connector.
behind the distributor , so the dog house will need to be removed. ill tell you what we need to do once that is accessed
here is the oil pressure switch wiring, we need to verify power and ground at the connector and then we can cross wires to see if we can influence the gauge.
then we can check the fuel level as well. same way
well i sent you links to the wiring did you not see them?
oh ok, first we will access the oil pressure switch , it is located under the distributor at the back of the engine, so you will have to remove the dog house or engine cover what have you.
