Correct. The valve could be sticking. Just throwing out another option

 

Ok well I replaced the fuel pressure regulator it seems to be running fine won't be sure until tomorrow mornin when I do a cold start. Now the next issue popped up is a p0108 code was thrown and I don't understand because I didn't touch the maf at all. And when I got the upper and lower intake manifold repaired that was 2days ago and now this. Does dorman make a map for their intakes? And my scan was readin the map between 0.30-1.07 ugh is this normal?

 

I was having the same problem it was stalling more often when I came to a stop or sowed down to make a turn, I replaced the regulator and problem was fixed.

 

Indeed problem is fixed now this morning was the first time since I got the car where it had a quick start

 

Can u tell which is which

 

WOW, interesting find!! Thanks for sharing your results on this!!

 

How hard was this? My car has been experiencing long-ish crank times when I start it within 30 mins of shutting it off and very ocasionally (once or twice) it stalled.

 

its not hard at all should take you around 30-45 minutes, depending on skill level. I would recommend removing your fuel pump relay and running the engine until it dies, then crank for another 10-20 seconds to relieve pressure in the rail. Its not fun having a large amount of gasoline splash up into your face, tends to cause problems then after that, taking the FPR out is straight forward

 

The hardest part for me was getting the snap ring pliers to fit into the seal, knce that was off it was smooth sailing. Csr has been starting good every since. Now to deal with the map and maf. Codes I've been getting. I'm hoping replacing the sensors will fix the issue

 

Update: also replaced the map and MAF this was also the problem. Got a aftermarket maf tho...seems to be holding up. I hace got even worse mpg but that could of been due to a bad tire I'm getting replaced tomorrow
