This is the case with both situations. I had the blinking security light after it stalled on the road. Waited about 45 seconds, tried once to start, didn't start and had blinking security light while key inserted, then waited another 30 seconds, and then was *LUCKILY* able to get the security light to stop blinking and start engine, but I'm guessing I got lucky. Drove to the closest auto part store, turned off the vehicle, then got the blinking security light while key inserted (again). Bought new fuses and wire in the store, did the test (pg 51) and replaced the fuses. (Failed test and needs bypass kit.) It seems to be VERY finnicky, working fine one minute, then having the issue again the next minute. too unreliable. It could happen again and for longer at any point in time. Need to fix.
So I'm guessing the bad circuit in the fuse box for EFI is also somehow connected to the random stalling in the road..
[EFI Fuse --> intermittent immobilizer start issue-----> random stalling while driving] The EFI fuse, or whole fuse box itself seems to be the root of the problem and could potentially leave one stranded either way.. has there really not been a recall for this issue??
Bottom line. If I'm not mistaken, it seems I indeed do need both a new fuse box, as well as the bypass kit. Will message you my info
