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 contact me for payment info or shipping cost outside 48 states.

Were you able to purchase? Curious as this form has been inactive for a bit. Need a bypass kit ASAP.
 
1998 LC crank but no start with no CEL on dash before cranking, security light blinking. This started a few weeks ago. the first time it happened i wait for a while and try again the truck starts right up. It was normal for a while. Then it gets worse in the past few days. I can’t kill the engine until l bring the truck back to the garage. I believe this is the fix. Need to order one. Thanks for your input.

Hello everyone, Thank you all for the great info. However Im still stuck...
Jumped the F port from the relay directly to the battery...can hear the fuel pump "buzzing" but im still getting the crank and no start while security light flashes...any help would be greatly appreciated
edit* Id like to buy the kit i just want to make sure this is my problem before i do purchase...seems like it might be a good idea to purchase even if its not as this is evidently an inherent problem with the 100series
 
Medtro, PM sent. Thank you.
