sounds exactly like my symptoms.. ive gotten in the habit of turning the key to acc mode, giving 1 pump of the gas then starting it up.. ive got an FPR sitting on my shelf in the workshop... but keep getting side tracked so havent done it.. its located towards the back of the engine bay along the firewall, the instructions i got to install it seemed very easy.. release fuel pressure.. remove old FPR (assembly around it has to be loosened first) install the new one and put everything back together in reverse order.. one of these days ill do it and be able to give a 1st hand account.. but until then heres the diagram from the vx cd manual... fuel pressure regulator is #9
