hey guys, so my 1996 gt has been throwing code p1443 which is relevant to evap emissions control system i do believe........
The most common cause of an evap code is a loose gas cap. Then a loose or broken evap line. Then the valve, then the sensor, then the actual charcoal canister itself. If you are smelling fuel it may be a broken line. Trace the line going off the rear of your upper plenum to the canister then to the tank. If you don't find a break then one of the other three components may be bad.
HW7 DTC P1443: CHECK THE VOLTAGE ON THE PURGE FLOW (PF) SENSOR CIRCUIT VOLTAGE WITH ENGINE RUNNING
Continuous Memory Diagnostic Trouble Code (DTC) P1443 indicates an incorrect evaporative system purge control valve flow.

Possible causes:

Obstructed, open or cracked hoses between EVAP canister purge valve and intake manifold.
Damaged EVAP canister purge valve.
Damaged PF sensor.
Key off.
Disconnect PF sensor.
Check for loose pins or broken wires by pulling moderately on the PF, VPWR and PWR GND circuits at PF sensor harness connector.
Repair as necessary.
Reconnect PF sensor.
Connect scan tool.
Key on, engine running.
Access EVAPPF PID.
Key off.

HW8 DTC P1443: VISUAL CHECK OF EVAPORATIVE EMISSION SYSTEM

Continuous Memory Diagnostic Trouble Code (DTC) P1443 indicates an Evaporative emission control system or evaporative canister purge valve (mechanical) malfunction.

Possible causes:

Damaged EVAP canister.
Pinched, plugged, blocked, cracked, cut or disconnected fuel vapor tubes/hoses between the fuel tank, EVAP canister, EVAP canister purge valve, purge flow (PF) sensor, and the engine intake manifold.
Damaged EVAP canister purge valve.
Damaged PF sensor.
EVAP CANISTER PURGE, or PF circuit shorted to VPWR.
Note: Fuel saturation of EVAP canister cannot be effectively checked by the canister weight or intensity of odor (smell).

Check for kinked or pinched fuel vapor tubes/hoses between EVAP canister, EVAP canister purge valve and engine intake manifold.
Check for cracked or smashed EVAP canister
