so its time to figure out the tach and fuel pump problems. I think/ pretty sure that i need a tach adapter from MSD, but which one? (8910 or 8920). The pump works when i simply jump it and the tach wast working when i fired her up for the first time. I am using the 6A ignition box with start/retard setup and OEM distributor. The magnetic pickup is not being used. I am also using the 89 Helios speedo (8k RPM), and i had to more the tach wire from one spot to another in the fuse box, just don't remember which one, but im sure i can figure it out, or maybe it was the coolant wire. it was something like c6 to c8.
