I have this kit installed for about 2 years now. Works great! Until yesterday where my rig is now not starting up and the red car icon is flashing. Does it mean it's time to replace the whole fuse box? I also have someone told me to look into the anti theft antenna?

Is the fuse still good?

Try connect the fuse holder lead to battery positive terminal if it is connected to A now.

The rig started up!

1. Does that mean the fuse box needs to be replace? And can I keep the lead on the battery terminal without draining it?

2. The rig keeps shutting off if I don't keep the idle up with the accerator pedal

That means you have new problem between battery and A. Connect the kit to battery to bypass this new problem.

Yes, you can keep connection to the battery without draining the battery.

Never seen or heard this before. Make sure there is no loose connection especially the connection to the battery.

Uninstall the kit, run a wire from battery + post to F, start the engine. Does the engine keep shutting off?

Ty for the help so far! You're the man! The rig is idling fine now. Not sure what happened. But Can you email me a copy of the original instruction. I have no reference to what is "F". My email is

This bypass kit bypasses the bad EFI relay circuit in the fuse box so that the immobilizer system gets adequate power supply for starting the car. I made this for myself after my new 30A replacement fuse - initial fix for crank but not start problem, failed to start after 4 days. Some members have showed interest in the kit and asked me to sell this kit.

This bypass kit is for you if:
  • You are told a new fuse box 82720-60023 will fix your intermittent starting problem but you don't want to spend $700 just for the part alone
  • You have intermittent starting problem and you replaced the 20A EFI fuse with 30A fuse or paper clip
  • You have intermittent starting problem and you have been tapping or removing/replacing relays and fuses in the fuse box
  • You want to have this kit in your glove compartment in case you run into this crank and non starting problem
The kit is designed to connect to EFI fuse slot. It is 100% plug and play provided there is no damage to the EFI fuse slot. If your EFI fuse slot is melted or damaged, you will need to connect the kit to the battery.

Kit comes with relay, 20 AMP fuse and installation instructions. Fuse holder may not be the same as shown in picture. $135 shipped to 48 states. Please send PM for payment info or shipping cost outside 48 states.

Hello Medtro, I definitely need your bypass kit. I have experienced this issue many times on my 2002 LX. Unfortunately, I just bought a new relay from the dealer! Anyway I can connect the new relay to your kit? Please message me when you have a moment. Thank you!
