Need help with temp and oil pressure gauge
Oil pressure gauge: With key on, it doesn't blip to max then back to zero. When I start the car it always goes to 60 psi and stays there.
-with IGN on, I can get the needle to max when I disconnect sender wire.
-IGN on and sender wire grounded to negative battery it stays at 0.
Temp gauge: ign on, it never blips to max then back to 100. When I'm letting it warm up in park, I can see the gauge start to move higher a little bit (like it's working fine), then whenever I hit the brakes the needle goes straight to zero.
-can't get gauge to max when sender wire is disconnected.
-gauge stays at the bottom when grounded (100 degrees)
The rest of the gauges work fine.
I don't know what to do next.
