Supra IV no start

I'm having trouble with my 2001 Toyota Supra IV, gasoline engine. It's got about 131000 km on it. The problem is that it simply won't start. I suspect the cable connections of the battery are not good. Has anyone else run into something similar?

A 2001 Toyota Supra IV with a gasoline engine is experiencing a no-start issue, suspected to be due to poor battery cable connections. Another owner with a similar problem suggests that the issue could also be related to the Engine Control Unit (ECU) malfunction. The recommendation is to have a professional diagnose the problem, which ultimately confirms a bad connection as the cause. The issue is resolved after the workshop addresses the faulty connection.

Did this summary help you solve your problem?

I own a Supra IV and had a similar issue a while back. 'Engine control malfunction' could point to several things, not just battery cables. The ECU (Engine Control Unit), which is essentially the brain of your engine, might be failing to communicate properly. Have you noticed any other symptoms, like engine surge or issues with fuel injection?

Thanks for the quick reply. Engine surge is not something I have noticed. How did you find out what was the issue?

In my case, the symptoms were intermittent at first, then became permanent. The car would sometimes start, sometimes not. Eventually, I had to take it to a workshop to get the ECU diagnosed. I would advise you do the same, and let a professional check the cable connections. That way, you'll be sure of the fault.

Thanks for the advice. I took it to the workshop as you suggested. Turns out you were right. It was indeed a bad connection, which they sorted out. Repair cost was 155€. Cheers!
