I have a 74 260 z.  She has had some troble with starting.  I rebuilt her but the wireing is so back wards I literaly can't get it straight.  It died on me on my way back from a dent. app. luckily i had a timing light in the car so i could tell the coil stoped getting power. So I ran a wire straight from the battery to the coil for about 45 miles until I found the EGR valve wire was running 6/8 volts and hooked it to the ignition coil. Having long ago removing the EGR entirely.  Then a month later the starter just stops working, New starter btw, and rechecked.  Tried to wire the seat belt safty togther and all I got was the relay by the fusible link next to the battery moaning like a virgin at jounior prom.  I'm at the piont where i'm going to have to wing it to rewire the whole car compleatly I guess.  Don't know what to do. starts up just fine when I "Bump" the starter with a screw-driver, but only with a compleat and full charge on the battery. Please any advice would help. Thank you!
