My vehicle one day just would not start; I was driving it all day came out of Target and wouldn't start. I replaced the starter, and it ran for 3 days and wouldn't start. I tightened the connections to the starter, and it started, and I drove it home and hasn't started since. Now my battery gauge doesn't show anything when I turn the key, no power to crank fuse and no power to ign-e, ecm-1, or eng-1. It has a new fuel pump, ignition module, starter and I replaced the battery cable. Any help would be appreciated.

If you don't have power to the fuse, did you mean then ignition A? Also, do you have the upper line vehicle? If so, you have a mega fuse that we need to check.

So, if you have no power on the crank fuse then we need to go back to the ignition switch and find out if we have power getting to it.

If you do, then the likely issue is the ignition switch.

So, I am attaching the wiring diagram below that will illustrate this.

Please run through this and let us know what you find.

Thanks
