Looking for assistance on this. Owner complained of "hard starting" which I determined was really longer than typical cranking time to start of 3 - 5 seconds. This vehicle typically started up almost instantly upon cranking. It needed a lot of service, oil leaks, and carbon removal of intake valves and runners, as well as spark plugs, and a general full service change of fluids, etc. No codes present before beginning work pertinent to engine. Completed the service which did not solve the long crank issue. Fuel pressures while running are within spec., HP fuel pressure raises as expected upon shut down on hot, but LP fuel pressure leaks down to 2 bars within 15 minutes of shutdown. I assume this car has a LP fuel pump prime function when opening the drivers door, or turning the key to ON. LP tank pump does NOT run in either of these cases. I back probed the fuel pump connector to look for voltage for prime function and see none. Voltage appears after cranking begins, and after engine starts. Fuel pump test indicates the pump runs well, and on-road performance is good, so I don't feel the electric pump is faulty, but I could be wrong. I feel the electric pump SHOULD be priming before starting, but I don't know where to begin troubleshooting.
I add the full auto scan below from today below as well as an engine scan from earlier that showed two codes which may offer clues. These codes disappeared without being cleared by me.
Any tips, assistance, or comments are welcome.
