Zero Power to Coil

[shaneyeend]

I have a 97 N/T, i have just finished puttingmy engine back in, i did a complete turbo rebuild, i attempted to turn it over, but the engine wont fire up, all systems have power, started turns, everything moves perfectly, have all fluids. Every thing is working, but the coil doesn't get any power, i traced the wires back to the PCM, and no power is being sent. I con't figure out what the problem is. Also any N/T guys, were does the long ground wire from the batery ground to? not the chassi ground. I believe i have it grounded corectly but i'm not 100% positive. Could that ground being off not alow the PCM to send power to the coil?

I found that my alternater choke fuse is blown, i figured that was the problem, which i have yet to figure out, the reason for this is when i replace the fuse it pops. it even managed to pop a larger fuse (i know that was a bad idea, but i wanted to see of that was my power problem) so what would be the reason the fuse keeps blowing?

Perhaps the alternator has a short. Disconnect it to see (don't let any of the wires touch anything - tape them up). If that isn't the short then see post #2 here: http://www.dsmtuners.com/forums/showthread.php?t=174504

touching the wires to a ground would blow the fuse right? or would it do something worse?

It should blow the 100A fuse if it touches ground (the big wire goes right to the battery) but don't trust it. It will melt wires and the electrical spikes that would result can fry an ECU (before the fuse blows).
