Use a liquid filled gauge that will read 4 or 5K psi.

I think the HPOP lines are 1/8 or 1/4 NPT. There should be a kit with lots of different connectors though

BEST way to read injection pressure is via a device on the data link connector under the dash.

The lowest PSI is 500 before it will fire.

Update for those who helped,took truck to mechanic,still wouldn't start,let it set over night again,he tried to start it the next morning and it fired right up,he drove it for about 50 miles got home and tried to start it again no start,started checking again,found that the ipr had a problem,pulled it out and it came out in two pieces ,had to get the other piece out with needle nose,replaced with one from ford never heard this before,I told him to drive it for a couple of days to make sure everything was ok.
Thanks jim
