Just about every time I start my car now I have to crank it a couple times before it finally starts, I think this is caused by low fuel pressure but I'm not sure. So would getting an aftermarket fuel pressure regulator help or is it not going to do anything?
i would start with a gauge, an adjustable regulator isn't any good if you don't know what your adjusting it to. or it might show you that that's not your problem. try leaving the key in the "on" position for a couple seconds then turn the motor over, see if that helps. it'll give it a couple seconds to build pressure.
same issue here
Sounds like a pressure regulator issue. I would want an upgraded adjustable one in there anyway with a stronger fuel pump.Quote:

My AEM Honda FPR actually bleeds off pressure very quickly. I have to crank 2-3 seconds after a long sit before the car starts... so for me, it was actually the aftermarket AFPR that caused the issue.Quote:

My car started instantly every time before the AFPR install... so for me it was the AFPR bleeding off pressure too quickly.
Hmm, I just bought one so I'll find out if it stays the same with me or fixes the problem. Either way I think it's something I've been needing since I upgraded the turbo's.
My Honda AFPR also drops pressure like a bad habit after the car shuts off. It holds pressure fine when the car is running, and increases pressure fine in response to boost. The main reason I installed it is to be able to tweak the injector flow a little, since the 560's flow higher at stock pressure.
Might be the spark plugs? I know mine are pretty black.
