Ok i had PO204 i change the plug part of the fuel injection now i got PO443 i change the gas, an purge solenoid did a smoke test all good there i think its electrical but not sure ive had this truck since 99 never had this code pop up what gives i also read the evap run on the same circuit as another stuff with the truck but all my fues look good

 

Open or short in the control circuit. If changing the valve didn't fix it, gotta check the wires.......

 

Thanks

 

Wiring is good changed my o2 sensors an the pcm

 

So i got a broken seat belt wiring my dash light a the bell goes off but how do test this for a short This is the one i need to test its wierd its been unplug for year but only now going a code
