Default 87 944 no spark with new speed and reference sensor

Hey guys I am new to rennlist and am in need of some help! I just bought my first Porsche 944 about 2 months ago non running. I was told that the speed and reference sensors needed to be changed so I did that. I was getting spark but no fuel. So I changed the fuel pump and fuel filter and dme and got it running but it was rough. There was no tach bounce but the car did idle. But that's it if I gave it any throttle at all it would die so I changed the fuel pressure regulator now it won't start at all!
So in total I have changed the
-fuel pump
-pressure regulator
-fuel filter
-speed and reference sensor and the dme. Now I'm getting plenty of fuel and the spark plugs are wet when I pull them out so the injectors are going but no spark and no tach bounce. PLEASE HELP ME!

TPS...new or used? AFM...spec'd for correct output/linearity?
