Cylinder filling with fuel

Asked by Jul 30, 2009 at 04:38 PM about the 1997 Pontiac Sunfire 2 Dr SE Coupe

Question type: Maintenance & Repair

Looking for ideas on 2.2L fuel problem. What would cause the #4 cylinder to fill with fuel? We're getting this checked but the machanic is scratching his head.
They changed the fuel regulator, injector and no change. Then thought about changing the fuel rail. But now find that on 97 it was incorproated into the intake manifold. I don't have deep pockets for someone to experiment and guess. If anyone has a good idea, I'd love to hear it..........thanks

I'm having an eerily similar problem. Have you found any solution?

Might be an issue with the valve not closing all the way, could be a bad spring
