Q & A

What issue is the speaker experiencing with the 2021 F250 truck?

The truck won't start despite having a good battery; the starter is not engaging.

What did the speaker notice in the garage prior to the truck not starting?

The speaker noticed a unique electrical smell that suggested potential electrical issues.

Where does the speaker suspect the problem lies in the vehicle?

The speaker suspects the issue is related to the fuse panel, which is poorly designed and exposed to water and dirt.

How does the speaker plan to troubleshoot the electrical issue?

The speaker uses a multimeter to check the fuses for voltage and continuity and attempts to reset the electronic control module (ECM).

What did the speaker find when probing the fuses with a multimeter?

The multimeter showed 12 volts on both sides of the fuses, indicating that the battery is good and there are no blown fuses detected initially.

What unconventional method did the speaker use to try to start the truck?

The speaker spliced a wire to bypass the starter relay and directly engage the starter, allowing the truck to start temporarily.

What is the potential risk of not securing battery cables properly in a fuel-injected vehicle?

If the power is lost unexpectedly, it can cause damage to the electrical system and the engine control unit.

What issue did the speaker mention regarding the starter circuit?

The starter circuit might be malfunctioning due to a burnt starter relay integrated into the fuse panel.

How did the speaker verify the condition of the fuses?

The speaker switched the multimeter to ohms to test for continuity, checking if the fuses were blown.

What does the speaker suggest as a temporary solution until the issue is permanently fixed?

The speaker plans to use the bypass method with the spliced wire until a more legitimate solution can be implemented.
