Sheit! I changed my oil today while I was mucking around installing a kill switch. Didn't change the filter. Got all done, fired it up, gauge showing no pressure! Dipstick shows full. I've run it about 15 seconds so far.
All other gauges working properly. When I turn the key on the oil pressure gauge actually drops some to the dead bottom of the gauge, then back to zero where it was when off once started. I did splice in a toggle switch to the power wire of the coil pack, that shouldn't have caused this. The oil gauge was working in the normal range, although I probably hadn't looked at it in the last few days.
I'm sure it's electrical but want to make damn sure. Anyone know where the sending unit is? '99 4.0 OHV.
