I installed my new Holley fuel pressure sensor yesterday and I am trying to figure out why it is not working. It is a .5 to 4.5v, 100 psi device. The first time I mixed up the power and signal wires, and when I realized that I fixes the issue. Also I connected it to ADC port 1, and I also tried port 2. I also formatted the WUD to display it and it still does not report any fuel pressure. Does anyone have suggestion on possibly how to fix it? I am thinking it maybe bad.

 

Swapping the power & signal wires may have taken out the sensor. Measure the output voltage with a DVM to verify it. How to set up the WUD:

Thanks Bob. I guess I will try replacing it. Also is it possible to add a oil pressure input to the computer and have it displayed on the WUD?

 

There is only a single area for pressure display. Although, if not running a WB can make the oil pressure sensor a preferred WB device. It will display in the WB area.
