When the drivers stop working, is it usually because they're loose or because they're bad?

I was under the impression most failures were from burned out/ shorted drivers. And that a lot were due to poor connections starting at battery and thru the pumps as well. This causes higher stresses etc on the drivers supplying current to pump. I don't know this to be 100% factual but sounded reasonable . Pump is the biggest current draw and if solid clean connections aren't maintained it stands to reason it would cause a issue.
Are the injectors not firing? The drivers are relatively easy to replace, if you can find a suitable replacement
