Default Why no start when hot?

I looked around and could find anything about it. Why is it when my car is hot it is hard to start? I'm running 650cc inj and Jeremy told me that was b/c of the inj, but he didn't say what causes it. Thanks in advance.

Well, you can try wrapping the lines with more thermal wrap, either that or you'll need more thermal wrap on the exhaust side of the turbo.

When I had my supercharger, I ran into the same problem when it was hot on 550cc. We'll see what happens when I get my TT setup

hey there,

sometimes with these cars and larger than 550 cc injectors it will have a hard start. if you hold the gas pedal down 1/4 throttle it will start right up.

I usually just let it sit for a min then start it up. I'm not worried about something being wrong necessarily. I was just wondering what actually causes it. Just for the knowledge.

The lines are wrapped w/ thermal wrap, but it comes up right against the pass side duct to the intercooler. I'm gonna see if it can be moved and if it can see if it will help. But first I'm gonna search and find out wtf "Vapor lock" is!

True.. But what is the fix for this? I mean its a PITA if you drop ur car off and people dont know how to start it after you tell them fifteen times....
