hello this sounds like a bad ground to the gauge cluster first thing to try with the key in the on position tap at gauge area see is there any change if not open dash area were gauges are wiggle to see if they are grounded good into dash grab a test light take end put to the ground on one off the gauges touch other power wire with probe while key is in the on position same for both gauges if no difference reinstall you need to check grounds on both gauges by tracing wires it might be easier if you locate your oil sending unit take the wire off attach alligator clip to wire now touch positive side of batterey if it lights grounds okay trace back to units oilsender,sending unit at gas tank goodluck please rate

Buick with a 5.0?? OK, regardless, pressure should not drop like that. Possible that fuel filter is full of **** & should be changed, or, you may indeed have a bad pump... (can happen). Sending unit: sounds like you have the leads reversed or the unit is somehow different than the one you replaced.

Make sure you put air in tthe tires, then find the reset button in the fuse box inside the car if not you can unplug the battery then put the battery back on.
