Electrical wizard needed!!
My '99 has developed a new vexation for me. When fired up from cold, the OP gauge reads fine, but the HUD OP indicator says zero. As it warms up, the gauge OP drops and the HUD OP indicator begins to work, but slowly (one bar at a time) until the gauge and the HUD read pretty much the same. Weird, huh? What the H is going on? There's only one sending unit (feeds both gauge and HUD), so it shouldn't be bad. HELP!!

Yes, the oil pressure gauge and the oil pressure display in the HUD. There is an oil pressure sending unit on the back top of the block and it sends its signal to both the gauge and the HUD display. How can they read differently?
