I love this fix, and it is the fix I intend to employ. I have ordered this kit. However, others have said the fix is to replace the fuse block with a new one. But I am curious...

If this is a common/known defect with the factory fuse block, would replacing it with a new one just be a matter of time until the new failed? I.e., do new replacement fuse blocks also exhibit the same defect?

IMO, replacing the fuse box isn't really necessary. The whole point of this kit is to bypass the internal circuitry of the fuse box, and like you said, the replacement fuse box could have the same issue. I actually think the bypass would be more reliable than replacing the fuse box itself. If you replaced the fuse box, you would still have to carry around a jumper wire just in case the 'new' fuse box fails.

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 $460 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
This kit is 100% plug and play, no need to splice any wires.

Kit comes with relay, two fuses (one for spare) and installation instructions. $85 shipped to 48 states. Please send PM for payment info or shipping cost outside 48 states.
