Rally dash oil pressure gauge issue.

The new sender could still be bad. The new Chineseium parts are crap.
Do you have an ohmmeter? If not Harbor Freight has them cheap (sometimes free).

Measure the sender to ground with the engine off. Should be about 80 ohms.

Measure the sender with the engine running. The reading should be lower, maybe 20-60 ohms.

Thanks Will do. I plan on shooting wires tonight or tomorrow. I do have an ohmmeter and I agree about todays knock off parts .It was a Standard brand unit although I realize that doesn't mean it isn' t Chinese. Truth is they don't want us keeping these cars around much longer I don't like the look of aftermarket gauges but will go that route if I have to I suppose. It just seems these a body dashes look better clean without things bolted to them.
