Fuel pressure during engine cranking
 

Does anyone know how much fuel pressure I should be holding while the engine is cranking?

My aftermarket FPR bleeds off pressure very quickly once the fuel pump turns off so in order to start the car, I have to leave the fuel pump diag. jumper in, however the car typically doesn't start until the 6th or 7th crank.
