81 911 Cis-k Test Questions

Since I Cannot Start The Car, It Quit At Operating Temperature, And I Have Not Been Able To Restart Hot Or Cold. I Got The Jc Whitney Fuel Pressure Tester And Recorded The Following With The Ignition In The On Position, I Heard The Pump Running.

Wur 9.9 Ohms
Wur Connector 11.5 Volts

Valve On Tester Open Cold(75f) 70 Psi
Valve Closed 70 Psi

Immediately After Ignition Off And Valve Open Drops To 32 Psi Within A Minute Its Down To 22 And Holds For 10 Minutes, After 20 Minutes Down To 21 Psi.

I Tried To Measure The Fuel Flow By Relieving The Pressure Tester Button Into A Jar. I Got 250 Ml After 2 Minutes Whether The Valve Was Open Or Not On The Tester.

Should I Be Testing The Pressure As I Am Cranking The Engine?
Any Guesses As To Whats Wrong?
