Flashing oil warning light

We need to start with checking the actual oil pressure with a mechanical gauge because I suspect you still have low pressure if the sensor and pump are new. If you do then that means you have excessive clearance in the engine which means it needs to be replaced or rebuilt.

However, if the actual oil pressure with a gauge is ok then we have an electrical issue so we need to start with this. Thanks

Thanks.

You are welcome. Let us know how you make out and we can go from there. Thanks
