Evap system is the canister purge, gas cap, pressure sender on fuel pump sender iirc, it could be that system is nit pressurizing? , you got codes?

 

No codes, running amazing past two days of all day normal driving. Stop and go, 50+ mile Highway runs at 70-80 mph, shutdown till cool, restart, etc etc.. Was told I can still smog with one pending. No worries, was just curious. Pics to come this weekend on my other threads(radiator thread & overheating thread). In-laws are in town so I'm pretty busy entertaining.

 

Smogged her today and she passed with flying colors. Guy said numbers were that of a newer vehicle. Very pleased with my rebuild/stroking. Cold air intake and flowmaster 10 series will go on tomorrow! Mpg's to come.
