Won't start

(2006 Chevrolet Uplander)
in Allentown, PA on December 28, 2010
There are a few times where the Uplander won't start. I actually have to rev the engine to get it to start. Any idea what may be causing this? It's under warranty but when I take it into the shop it doesn't do it so they can't verify that it does in fact not start at times so they can't fix it. If anyone has any clue as to what may be causing this and how to fix it I would greatly appreciate it. It also does it in all kinds of weather so it's not just in the cold or anything.

to add to crashd, you should leave it at a shop and let them do checks like fuel pressure among other tests so they can narrow down the possibilities. you dont want it to leave you stranded anywhere.

yeah i agree, if you can leave it for a day or 2 makes a big difference. i can speak from personal experience here, it's very difficult to catch intermittant concerns, and almost as difficult to get the customer to leave it long enough for me to find it. so please be kind to your mechanic, he wants to fix it as bad as you want it fixed.

Why would you not want to be stranded. I hear it's good walking weather up there now.

try 89 octane first!!!I'm telling you, you'll noticed a big difference

This is kind of a shot in the dark, but i have run accross MAF (mass air flow) sensors that can cause something similar, and it won't always leave a code to help catch it. you might have your repair shop check the MAF and clean then see how it starts.
