Has gas, has power, has good relay, and new pump. Won’t start or pump gas. Just driving down the road and it just stopped running. Any ideas?

Make sure G117 and G403 are good grounds
Test for a prime voltage on dark green/white.
Test for a prime voltage on output side of relay (Gray)
Make sure 20A ECM B fuse is good and you have 12v in and out.
Test fuel level sensor in tank and make sure it is passing voltage.

Let us know what you find out.
