I have an LS3 Rod that has an inconsistent start then immediately die condition. Intermittent because sometimes at random it will start and run fine.
I have changed crank sensor as well as checked the powers and grounds. All of the sensors seem sane. As the intake system isn't conducive to a properly functioning MAF I have tuned it in Speed Density. Attached is the tune file. Any thoughts? Thanks!
