Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.

In order for the engine to start and run you need good spark to the spark plug, injector pulse at the injectors and proper fuel pressure (55 to 62 PSI) . If you can check each one of these things and post back with which one you are lacking we can work from there to get this resolved.
