Or anyone else who might have the answer.

Can you get me the Voltage to Pressure Map for the fuel pressure sensor?

I am trying to find that for you so far all I can find is

3.35= 50 psi and 2.8 volts= 39 psi.

those are the only values the PC/ED book has

I found it on one of the tuning forums. Here it is for future reference.

Gasoline Vehicle-Fuel Rail Pressure Sensor Expected Voltage

Voltage (dcv) Pressure (kpa) Pressure (psi)
4.5, 482, 70
3.9, 413, 60
3.4, 344, 50
2.8, 275, 40
2.2, 207, 30
1.6, 138, 20
1.1, 69 , 10
0.5, 0 , 0

Note that the curve variation can be +/- 2.5%
Voltage values were calculated for VREF = 5.0 volts. These values may vary 15 percent due to sensor and VREF variations.
Fuel Rail Pressure Sensor 9F972.
This is out of the

2003 Powertrain Control/Emissions Diagnosis Manual

how did you find it in there. I looked in the 99 PC/ED manual and could not find it.

do you remember what section that was in?

Someone else looked it up for me. I found the same two values you did in the 99 ford CD manual. This is close enough for me to work with. I'm just hooking it into an anolog input to datalog.
