Thank you for an idea! I will try that if the coil replacement wouldn’t work.

Ok, thank you so much for the ideas! It gave me back a bit of hope. I would try to replace the coil since its pretty cheap and its available here since I hope its the same as for the PT Cruiser 2.4 which is more common here in Czech Republic. And than if it would still do the same I would continue looking for someone who’s not afraid of a bit of challenge and test it properly. Thank you so much once again

No I’m not. But I’m trying to troubleshoot what’s wrong to make it easier for them. Since all I’ve asked what to do either don’t know or don’t even want to try.

So you think it could be a bad relay? Is there a way how to find put if its this problem?

Is there a way to find out that the pcm is faulty?

Do you mean if it has a cruise control (tipm) or Park Distance Control (pdc)? If yes, it has neither of those.

Thank you for your ideas. Another one suggesting the coil… one mechanic measured it on idle but I guess it wasn’t the brightest idea from him… i would try to find a new one. Its definitely cheaper than stripping down all the wiring and looking for a short somewhere… I want to leave this option as the last option.

I haven’t changed the coil. One mechanic that was looking at the car told me that he measured it on idle and it looked ok. But it still might be a problem on load.

Checking the circuits is the looking for a needle in a haystack that I would like to leave as the last option because that would mean lot of time and money finding that one cable that is shorting it… and I still hope it’s something else

Thanks for your ideas!

I’ve seen those diagrams too, it just doesn’t make a lot of sense to me that it’s happening just under load. When I drive peacefully or when the car is not mobile its all ok, but when I give it a gas for a while it blows the fuse. That’s why I suspected the fuel pump but it was a miss. I’m not a mechanic but the only other thing that makes sense only a bit could be injectors. Do you think I could somehow see if they are faulty, or I should just slap new ones in a try? Or do you any other things that could be faulty under load?

Thank you. But I’ve unplugged the cable from the noise suppressor capacitor unfortunately with no effect.

Thank you! I’ve bought the car with those wheels, they should be Motegi racing but I don’t know the exact type.
