Ok the truck was running battery went dead we replaced the battery and terminals, truck started back up ran fine for a couple days, then a couple days later it wouldn’t start again so we changed the alternator still would not start so we changed the starter still not starting . when turn the key it just makes a click and thats it, thought maybe a bad starter so replaced it again and still nothing , help can’t figure it out.
When you say then nothing. Are you loosing voltage when you turn the key to crank position? Also I been coming across alot of same condition on resold vehicles where a gps kill switch has been installed and is malfunctioning. Key on arc the solenoid on the firewall with a screwdriver…if truck starts look under steering column cover for gps spliced the into ignition switch. Hope this helps.
