2001 4.8L starting problem

Hi everyone,

I've been having an ongoing problem with my 4.8L 2001 Silverado. It seems that every so often when I try to start it, it cranks fine but will not fire. When it does start, it kind of chugs a little for about five seconds then runs fine, it feels like a fuel starvation problem. No problems while driving so I'm kinda baffled. I've changed plugs, fuel filter (I think there's only 1 right?). I also have a K&N FIPK system on it which I clean regurlarly.

Any help would be greatly appreciated.

Thanks,


Mike from So Cal
