most aftermarket parts wont hold the pressure for very long


i bet if you had a gauge you could read , it would be 0

yup


when the pcm turn the pump on , its only for 2 seconds , which in some cases isnt long enough to get enough pressure


then once you start cranking the , it takes a few seconds for the pcm to turn the pump on again


which causes the extended crank time
