Hey everyone,
I’m having some strange issues with my ’07 100 and could use some insight.
Here’s the background:
I’ve been working on fixing it up and recently took it camping. It was running fine—got to the campsite, parked it for a few days. When I went to start it back up, I turned the key to the run position, it did nothing for a second, then cranked and started. I noticed this but brushed it off as user error. I drove it around with no problems that day.
The next day, though, I tried to start it, and now there’s no crank. My first thought was that it might be the battery, so I checked all connections, tried a jump pack, used jumper cables, and even swapped the battery from a GX. Still nothing. Thankfully, my brother came to the rescue and flat-towed us home.
Here are the symptoms:

Here are the symptoms:
- All interior electronics and external lights are working, and the key unlock works fine.
- Tried the spare key—no difference.
- Jumped the starter relay, and the engine cranks, so the starter seems to be working.
- I can hear the relays clicking when I turn the key to the run position.
- No communication with the ECU using either a Bluetooth scanner or a regular scanner (going to try my Techstream laptop today, but I don’t expect a difference).
- From what I’ve read, immobilizer issues usually lead to a crank/no start situation, so I’m leaning away from it being an immobilizer issue.
- Could it be a fuse problem?
- Why is the ECU not communicating? Could it have failed?
- Find the relevant pinouts and check for ECU power and fuses.
- Possibly replace relays.
- Explore ECU replacement options.
- Hope to get some advice here on what to try next.
