Thanks a lot BlackWorksInc. You were right. Changed the new Denso pump (it may well be a fake Denso even it looks very well constructed, like OEM) back to my original OEM pump after putting a new pump motor on it and that was the end of immediate zero pressure after turn off and no more...
I am trying to figure out why recently I get occasional longer cranking times.
The fuel pressure goes to “0” inmediatly after turning off the engine. (Running is at 40-41psi.) Is this definitely abnormal? No obvious leak…
Thanks
