I have a 2009 touring 370z and recently installed 660cc injectors and a AEM 340LPH fuel pump. I believe I have done everything correctly and last night I got the car to start and idle fine on the first attempt. It is now the next morning and the car refuses to start but will still turn over. From what I can tell audibly, it's very close to starting.
I checked the fuel pump fuse already and I'm thinking of draining the fuel rails and fuel pump and trying to start it again, any other ideas/suggestions on what I should do?
I have no other major mods besides exhaust bolt on's and headers.
EDIT: fixed the issue, my battery was just dying and I've spent the past 3 days trying to diagnose the wrong issue
