Was Startin to act like it was not getting enough fuel around 5 000 miles ago, but not seem like it was cutting out. Let a friend drive and after he added oil, drove it a week or so and found out he didn't put oil cap back on. Few weeks later, cranks but won't start. Fuel pressure is good. Just seems like not getting enough fuel to start.
