  1. Check your fuel pressure. 9 times out of 10 on these newer trucks, hard starts are caused by low fuel pressure (even 1 psi low). If I recall, key on, engine off should be 65+ PSI, and engine running should be 55 psi. This pressure is checked with a guage on the Schrader valve on the fuel line. If your pressure is low, then it's usually either a clogged filter (which you have already replaced), a bad regulator, or a bad pump. In my experience, it's usually the pump. Many have told me it's usually the regulator, but on my fiancee`'s Jimmy, the regulator (original) is still good, but I've had to replace the pump twice due to hard/no start conditions.
  2. Whenever your service engine soon light comes on, you should go to either a dealer or an autoparts store like Advance or Autozone and have them read the code. The code would be very helpful in determining what is going on with your truck, as it gives you a place to start from. That being said, it sounds like you did get some bad gas and it's causing a misfire condition. Still, get the codes checked out first. No point throwing money at a problem that you don't REALLY know what it is.
  3. Here's another one from Mid-Michigan...Just picked it up Tuesday.
