Hello all, Noob here.

I have a 2004 Convertible (5.0) and when I go to start it, unless I let it sit for a second with the ignition on, it will not start right away. It's acting like I am loosing static fuel pressure in the rail when the car sits. Is there any easy way to differentiate between the Fuel Pressure Regulator and the Fuel Pump being the cause of this? Thx!

2004's dont have 5.0's
they dont have fuel pressure regulators either
its a 4.6l engine, with a returnless fuel system.


if the above mentioned car DID have the equipment you listed.. it would either be a FPR issue OR a in take fuel line issue

Thanks, I just bought the car so I plead ignorance. Any idea what might be causing this? If I sit with the key on for about 5 seconds, it starts right up. However on a cold start it will turn over for about 5-7 seconds before starting.

Any advice would be sincerely appreciated!

fuel pump control module more than likely... although you would get more accurate assistance if you go post in the 4.6l forum
