This is the filter replacement proceedure. If it hasn't been replaced in a while it is a good idea to do just for maintenance.If that doesn't get it started repost in this thread, there is no need to start a new one. If it still doesn't start can you pay close attention to the check engine lamp and the security indicators. We want to see the check engine light come on for a 3 second bulb check then go out. The security indicator should do the same let me know if either is different and also if you have a test lamp and fuel pressure gauge to further diagnose. Please ask if you have more questions.

If you need info on how to disconnect the quick connects here it is. Plese do wear eye protection. No matter what you do there will still likely be some pressure at the filter.
