Electric problem

[Dekster]

I have a 91 5.0 with an electrical problem i believe.

When i try to start it and turn the ignition i get a buzz under the dash and thats it. Also my tac bounces all over the place.

I had an amp and subwoofer hooked up but I unhooked it to see if it was causing problems. I also replaced the battery.

Any suggestions?

I thought i saw someone mention to check grounds in another thread but i couldnt find it searching.

Thanks in advance.

Most likely Starter Relay or Ignition Switch. Don't continue replacing good parts, i.e. battery, which is easily tested.

Is this a no crank when your turn the key to the start position or something else?
