2000 Pontiac Grand Prix Q&A
2000 Pontiac Grand Prix Question: Where is the Fuel Tank Pressure Sensor located in my 2000 Pontiac Grand Prix Gt?
V6 3.8L 2DR Coupe My car suddenly began having problems. It starts fine & stays on for a few seconds then suddenly just stops sort of like a loss of fuel but without all the putting. Like a drainage of some sort. I can hear the fuel pump working so I assume it could be a relay or sensor. I cannot find where the Fuel Tank Pressure Sensor is even located?? could you help me? any advice would be greatly appreciated. again, I am guessing here. Pure speculation but I still need to know where its at though. Thank you. God bless! - Lil717
The sensor in in the fuel pump module, but it only works with the EVAP test. IT reads the vacuum on an EVAP test only, Check your fuel filter. - ProfessorG
The fuel tank sensor only work for the EVAP system it is NOT part of controlling the fuel pump The sensor check the gas tank to make sure we dont let any gas fumes get out by do a pressure test is the fuel tank, there can be several cause to the start and stall To save you $ on trying to fix this your self. Bring the car to Bills On Broadway and we will fine the cause and Quote the repair Thanks Bill - Bills On Broadway
Another possibility is the oil pressure switch. If Engine starts and runs a few seconds then dies this could be your problem. Fuel pump comes on for a few seconds to start car, then the fuel pump circuit is thorough the oil pressure switch. This is so if you loose oil pressure, car will shut down and engine will not be ruined. - Dr Quick
Is the check engine light on? Do you know what/where the Mass Airflow sensor is? - pushrod
