hey i just threw on an aem fuel rail and regulator and now when my car sits for a while and i get in to start it up the motor cranks alot longer than it used to before it starts. i thought maybe i had a leak somewhere but checked and re-checked for leaks im sittin at about 42 psi so i think it would be pretty easy to track a leak down...i even let the fuel pump run a few seconds before hittin the starter. if anyone has any ideas on whats might be happening i would appreciate the help thanks alot

 

Put the stock regulator back on.

 

how does it idle after start up?

 

it idles at about 650-700 when its warmed up which was about what it idled at before i put the rail and regulator on and runs just fine once it is started...so im kinda lost on what to check next
