When you had this issue, did the engine light come on, and did you do any specific checks before finding the problem? I have basic diagnostic tools; are there codes I should look for related to ECU failure or fuel injection?

Yes, the engine light was on. I tried some basic checks, but without specialized equipment, it was hard to find the cause. I took it to a workshop. Given your symptoms and potential ECU or fuel injection issues, I'd advise doing the same.

After checking the battery cable connections, they were faulty. I replaced them, and the car now starts. The repair cost 155€. Your input helped guide my troubleshooting.

I had a similar issue with my 807. Before assuming it's a cable issue, have you checked the engine light or tried any diagnostics? I'd check for ECU failure and the fuel injection system.
