Oil Pressure Troubleshooting

Hello everyone,

I've got an 87 Z31 NA I picked up recently that always just shows no oil pressure. I picked up a replacement sender unit, did a full oil change with a synthetic blend, cleaned the connector, fired her up aaand...still shows no oil pressure.

Just hoping someone can point me in the right direction of what I should look at next, is it typical for the gauge itself to fail? The car drives just fine, so I'm pretty sure it's not a case of actually having no oil pressure!

Check the wiring. And make sure you've downloaded the FSM:
