Oil pressure gauge sender unit will be on top rear of engine by dist.
There is a gauge and dash panel fuse in cab instrument panel fuse block.
In the under hood fuse and relay block there is a ECM-B and also a ECM-1 fuse
One above fuel pump relay and one on left side of it.
Pull cover off and they should be labeled on under side of cover.
If you have had a short out turn key on and check all fuses for 12 volt power on both side.
Let us know how it goes.
