Well, I'm fairly new to this also, but maybe we can come up with a solution. Not knowing if you've run the truck before, or if this is the first time(from new) you are firing the truck up I'll give ya a couple ideas. If the truck is new, then it's probably rich and flooding and it the high idle might be set from the factory b/c HPI instructs users to idle through first few tanks. Something I haven't had any luck with. Normally I'd say it sounds like a bad glow plug. Sometimes the vehicle will start and actually run for a bit then die suddenly. Try replacing and see what results you get. The next step would be to give the truck some gas with the glow starter on and see what kind of reaction you get. If it spits tons of fuel then it's more than likely too rich. If it runs fine and accelerates then I'd say go ahead and replace the glow plug. Good Luck. And don't be afraid to stop by your local Hobby store. They are usually more than happy to help (as long as you're patient I find). Besides, you'll probably be buying parts from them anywhoo.
