Door opening (new): motor runs for a six to seven seconds. this is consistent all the time, it may take less sometimes but not more.
Key on but with engine off -dash lights on: Motor runs for one second, cycles every two and a half minutes or so. (at 65F) it takes about a second to get to full pressure. this is consistent all the time.
Engine running in neutral : Motor cycles every 80 seconds or so today at 65F. it takes about a second to get to full pressure. this is not always consistent. Yesterday, the pump was cycling every 10 seconds, warm??
Then shut car off but put key into on position again: Motor cycles every two and a half minutes or a bit more (160 to 175 seconds). it takes about a second or less to get to full pressure.
Then how many shifts do you get before you get pump to cycle ..: Every shift causes massive pressure drop, to 30 bars or so, causes pump to cycle each and every time. It takes about a second or less for the system to get to full pressure.
Shift from 1 to n to 1 and let me know how many shifts before pump turns on ..also note the same as above duration .. Every shift causes massive pressure drop, to 30 bars or so, causes pump to cycle each and every time. It takes about a second or less for the system to get to full pressure.
Do the same shifting with engine running.. Every shift causes massive pressure drop, to 30 bars or so, causes pump to cycle each and every time. It takes about a second or less for the system to get to full pressure.
thank you so much for your help, I am puzzled why idling would cause additional pressure drop. I attached some screenshots of system pressure.
