My daughter has a 98 Contour, 2.0 Zetec. It cranks fine, but won't start. Every once in a blue moon it sounds like it "fires", but never more than (probably) one cylinder. I've replaced the fuel pump, her step-dad replaced the filter. I've disconnected the line to the doo-dad on the firewall behind the throttle body and do not have any fuel going there. Can someone tell me what that doo-dad is? Could this be the pressure regulator? It has a line from the filter, and goes directly to the throttle body, and has one electrical connection on the engine side. The fuel pump shut-off appears to be reset. The fuel pump comes on with the ignition, but sounds like it only runs for a few seconds. Any and all help is appreciated. I'm a fairly technical guy, but without a great schematic of the fuel system, and electrical system, I'm reduced to easter-egging this problem
Thanks,
Alex
