I have a very small leak in the fuel rail. Would this cause a no start condition? Would cause a high idle speed? Thanks

 

Yes it could, or at least it did in my case, I had a leak at one of the injectors, just turned out to be a bad O ring. Where at on the fuel rail is it leaking? Even if you do get it running, don't drive around with a fuel leak, fix it.

 

It is in the rail, a small hole. I am going to replace the rail. Just wondering if I need to look elsewhere for the no start.

 

Ah I see, yeah it could because of the leak. Replace the rail like you said you were, and make you sure you get some new o rings too for the injectors and fuel lines. Good luck.

 

As with any problem you have to fix the obvious before you can work on other things. You know where the leak is, fix that, then see how it runs. Then work from there.
