Check all of your cable ends for corrosion behind where the lug is crimped on the cable. I've found them completely corroded apart while the heat shrink holds it together. My truck has 4 main grounding points.

1- under fuel filter on the block
2- at starter negative post
3- on outside of frame rail next to starter
4- at the driver side cab mount
