My son has a '89 S10, we just replaced the engine and it ran great, went to crank it a few days later and nothing, no turn over, no lights, no horn, etc... Battery is good, terminals look good, no broken wires that we can see from the top. Turn the key and you get absolutely nothing. Any ideas?

 

Don't worry, the Lord let us know what the problem was and now it runs.

 

What was the problem?

 

1 wire against the firewall was loose and the wire going to the alternator had come loose.

 

At least it was a cheap and easy fix.
