just finished putting in a motor in my 90 formula 350.have everything hooked up and go to fire it and no spark. i have changed out the cap, rotor and even teh icm.all these where pasrts from the old dis. i now have a msd one in there. i also hooked up a msd 6al box and there was a buzzing sound and some sparkage turned the key off.now if i turn the blinkers on i can hear the fuel turning on and off. any ideas, how bad do you think i fried my computer or something???please help at my wits end w/this car now

 

Got all the grounds hooked up behind the heads? Did you scratch the paint opff the heads to ensure good connection? Have the small braided ground on the pass side head (or intake?) to the firewall?

 

If its tpi have autozone test your ignition module.
