Has anyone ever had trouble with their immobilizer system? (1 Viewer)

[fengler]

Mine seems to work intermittently and i noticed the solenoid for the drivers door mechanism seems to be shady. Its really odd, sometimes i have to do a weird unlock/lock procedure in order to get it to start or else it just turns over and doesn't fire. The blinking red vehicle/key light is on (next to the clock) when its cranking. Even though, i have a programmed key and a programmed FOB, and the green ring even lights up, it wont fire. Like i said, this happens intermittently and i think it may have to do with the drivers door lock somehow, but im not sure. Anyone else have this problem? Edit, also note this beast has 212k miles on it.

open your hood and fuse box...... while someone is cranking the engine tap on each of the relays see if it starts... I'm not sure exactly which relay but it seems the one that controls the fuel injection is the one that is the prob. but not 100% if you look at my earlier post on the relay... that was my issue

Its actually interesting you say that, because the first time this happened, i had no clue what was going on, so i popped the hood, plugged/unplugged fuses and relays and it worked. This problem only happened after i had the entire vehicle, inside and out detailed. Electrical gremlins are the worst!

I just did what you said as another quick check and it fired up. First, I unlocked it, tried to start it, no dice. Took keys out, popped hood, tapped on all relays with a master lock (small weight), went to start and it fired right up. Hopefully others will find this helpful as well!

See the thread that says: " fix for immobilizer issue" . Replace your EFI fuse even if it looks good.
