Hey all,
I did a bit of a search but couldn't find anything similar to my issue.
The problem: When I crank the car after the engine has been running for a bit, it doesn't really want to fire. Sometimes it will crank for a bit longer than usual and then fire, sometimes it will crank and I can hear it trying to fire but it dies if I don't give it some throttle, other times it will just crank and crank and crank and refuse to fire even if I give it throttle, and sometimes it just starts normally. There is no problem at all on cold start, it always fires instantly when I turn the key.
The background: I've had a slight hot start problem ever since I had my injectors (and turbo, but that seems unlikely to be related) installed and the car retuned. However it was never so bad that it refused to fire or required any throttle, it just made a strange sound when I cranked it and took a bit longer to start than it did when cold. It has since gotten worse after I relocated my battery to the boot, though I'm not sure if it is likely to be related or not. I had it at my tuner last week trying to sort out another issue, and I did ask him to take a look at the hot start but he said when he tried to have a look it fired normally so wasn't sure what the issue was.
The question: My first guess is that this is most likely the hot start mixtures? Is there anything else it could be, eg. electrical problem or failing sensor?
