I have replaced battery, starter and alternator still nothing. All lights and radio work. Only the battery gauge works. Before I could restart the truck and it would be fine, now it won’t restart at all. Check all fuses as well they are fine.

Hi,

The first thing I need you to check is the starter fuse which is under the hood in the fuse box. Pic 1 below shows the entire wiring schematic for the starting system, so we need to go through and check things. The fuse is first.

Pic 2 shows the fuse location and the starter relay. First, check the fuse. If it is good, confirm there is power to and from it. If there is, switch the starter relay with a different relay in the box that has the same part number.

Here are two links you may find helpful:

Let me know what you find or if you have other questions.

Take care and God Bless,

Joe
