Reply To: Intermittent Hard Start and Evap Leak in 2007 Chevy Suburban

I’ve experienced a similar issue with my 2006 Chevy Suburban, and it was quite frustrating. In my case, after numerous attempts, the car would eventually start, but the cause seemed elusive. I suspected the fuel pump initially, but the lack of a clear pattern made it puzzling. I also considered the possibility of a leaky fuel injector or an evap system problem, just like in your situation. It’s a challenging problem to diagnose, but your approach to checking various components is a good start.
