Hello everyone,

I'm quite new to the form since i have issues with my dad's 1990 300zx tt 2+2 with 30k miles. I live in the Netherlands and road taxes are ridiculous right here se we decides not to drive it for almost 3 years now. it has been sitting for almost 10 years in total. however 3 years ago we decided to start her up again and drive around to give the old lady some fresh air. a year or so ago we decided to do the exact same thing like we do almost every year. We never had a problem after sitting for a long time it was just charging up the battery and just turn it on. But not this time. This time it refused to start and since then we are trying to get her working again. It cracks but just doesn't start. We flushed the complete fuel system and we replaced the sparkplugs but we ran out of ideas since everything should be working like the day we drove it under the carport and shut it off.
anyone ideas over what we could try?
