ok so heres the deal sometimes my coupe with start right up sometimes and sometimes i have to turn it over a few times before it starts. and a few times when you first start it will start then fall on its face and die it does seem to idle a bit low sometimes other than that no problems it never stalls or shuts off after i start driving it. for some reason i think my fuel pump is about to go what do you guys think if so

 

and just about everything on it is new no vacuum leaks and no CEL's

 

do you let the fuel pump fully prime before starting? get a fuel pressure test to see wht type of pressure the pump is putting out.

 

Its prolly not gonna be fuel, more likely gonna have to do with your IAC motor bein dirty or your TPS being bad, also does it matter what the weather is like when it does or doesnt start? It could also be your coolant temp sensor, if its not reading right it will flood the car on startup and make it shut off, lemme know if it changed with the weather on how it starts

 

could just be a bad fuel relay. happend to me. most of the time i had to give it a tap with my foot with the igntion on, i would hear the fuel pump priming up and away i went with no problems until i turned the engine off
