Relays problems

If the alternator is not charging the battery, the battery will eventually drain and the vehicle may not start. Here are some things you can check:

Check the alternator belt: Make sure the alternator belt is tight and not slipping. If the belt is loose, it can cause the alternator to spin too slowly to effectively charge the battery.
Check the alternator connections: Make sure the connections between the alternator and battery are clean and tight. If the connections are loose or corroded, the alternator may not be able to effectively charge the battery.
Check the alternator itself: If the alternator belt is tight and the connections are good, you may have a problem with the alternator itself. You can have the alternator tested at a local auto parts store or mechanic to determine if it needs to be replaced.
Check the voltage regulator: The voltage regulator is responsible for controlling the voltage output of the alternator. If the voltage regulator is faulty, it may cause the alternator to not charge the battery.

If everything worked be for you took fuse panel out I would start there. I had to replace fuel relay but I cut connection wire from plug and put relay that was easier to get to and there’s a wire that shuts pump off so it wouldn’t flood the motor fine it and hook to relay but it will still run even though you just wire in new relay - the problem with taking fuse panel and replace relay is it could go out again it gets hot behind the panel and that’s the problem usually

Did you try removing the crankshaft position sensor and make sure that it isn't gunked up or have a break in the wire
