Im having troubles trying to figure out why my car likes to start some times, and sometimes it wont... when it's cold and not warmed up it starts up sometimes, then after I drive it, and let it sit in one place for like 2 hours its a pain in the butt to start, or just will not start at all. I have to let it sit for a day. It acts like its flooding its self. I have just replaced the fuel pump, fuel filter, fuel dieaframe, and today I just installed new injectors and deleted the cold start injector valve, because it was leaking pressure out of the rails I thought at least. well the pressure still leaks out and I have no idea why. the car just cranks over and over.

 

Does the pump prime when you turn the key on?

By the battery, between batt and fender, there is a fuse in a weatherpack - should be 20 amp fuse - find it - is it blown?

 

Yes I can hear the pump prime when trying to turn the car on and then it pimes when i turn the key off. the fuse is fine

 

Ok so I fould out my pressure was coming out of the top of the fuel rail were you can check the pressure. so I tighten the little guy in side it and it holds pressure.. but it's still not wanting to start when it's cold. Another detail I noticed that when I first go out to start my car it cranks over really slow the first two turn overs then it turns over normally, and starts sometimes(when cold) could this be a bad alternator or battery? both are pretty new... and I also have a new starter solenoid I replaced not to long ago.
