I have back pressure in the fuel tank and its hard to put gas in. now my van will not start.
code readout came up: Emission Control System: PO446: Vent circuit half; PO452: Pressure Sensor low; PO453: Pressure sensor high.
I can start the vehicle but there is no power to the windows or other accessories. Is this an ignition assembly problem?
My 1997 gmc safari when cold, runs very choppy and rough. Once it warms up, after a few miles, it runs great. What could be the problem?
