83zed owner Posted April 15, 2010 Share Posted April 15, 2010 Okay so here is my problem, the car is a 78 280z 5 speed, only issue it's having is starting when hot, it just cranks and cranks and nothing. if i let the car sit for at least one hour or more it starts up fine,i know for sure this is not normal at all, any one have any input or experienced this problem before?

PanzerAce Posted April 15, 2010 Share Posted April 15, 2010 Might be the fuel boiling as well. Does it not start *at all* when hot, or does it just take longer than usual? Quote Link to comment Share on other sites More sharing options...
83zed owner Posted April 17, 2010 Author Share Posted April 17, 2010 okay, so i found a little trick to get it started when hot, all i have to do is give it gas when cranking the first time i try, if i do not do that, the car will not start at all no matter how many times i try, so I'll have to wait till it is completely cold, for it to start by it's self.

19762802+2 Posted April 17, 2010 Share Posted April 17, 2010 Do you have the stock EFI or a carbs? and Do you have a mechanical pump or electric? Quote Link to comment Share on other sites More sharing options...

Do you have the stock EFI or a carbs? and Do you have a mechanical pump or electric? EFI, with what should be electric. Quote Link to comment Share on other sites More sharing options...
