No Crank No Start Help
I just completed my NA to S5 TII Swap in my 89 vert when i was done i added the radiator and battery and i attempted to start and nothing the clock just dims. i have power all through the chassis on the engine starter has 12Volts signal wire does not receive Voltage when i hit the key so at the time ive checked so far the battery -12v ive checked the main fuse box it was 12v both sides of the wire leading to the ignition switch. my suspects are the starter cut relay, should i jump this relay direct ? is there any reason the computer might disable the starter besides security reasons ? and the other switch i suspect is the interlock switch but i dont i will be spending most of my time checking it if anyone has run into this problem after a TII swap i would sure like to know, any info is appreciated

Computer has nothing to do with cranking (turning the engine) only with starting it (supplying signals to sensors, injectors, coils, etc.).
Power goes from battery to ignition switch, through clutch switch, and to the starter. One of those is at fault if you get no turning of the starter.
IF you get no 12vdc+ on the small starter wire (ground voltmeter), it is not the starter. Check for +12vdc coming out of the black/red wire at the ignition switch when turned; if you have it there then it is wiring or the clutch switch; if not, it is the ignition switch or the connections at the battery.
