I have a stroked LS2 with a blower and run a speed density tune with a 2 bar map sensor. I am now getting a P103 code (maf or vaf high output). For some reason I am getting a 0 fuel pressure reading on my pillar mounted digital gauge. I am getting a 60psi reading on my fuel rail mounted gauge which is normal for that gauge. The digital usually reads 89 to 99 psi since I have dual pumps. It also takes three tries to start now when it used to take one turn of the key. I am lost and cannot figure it out.
