Joe,

This IS the place to discuss car problems. That is why we are here.

If you had to add a switch to keep the fuel pump working, the Fuel Pump Relay may have failed.

If you are smelling raw fuel and flooding (too much gas) there may be a problem with the Fuel Pressure Regulator leaking into the vacuum hose. You can remove the vacuum hose and look for liquid fuel - There should be none in the vacuum line. If there is liquid fuel, the Fuel Pressure Regulator diaphragm may have ruptured. leaking through ot the vacuum line.

Good luck. Keep us posted.

 

Thank you Vaer,

I got another problem is I am Taiwanese, my English is not as good as you do, especially those words about car parts......

I have to understand then explain to my friend, so he can know what to start, that is why I ask for pic, I will tell my friend to check the parts fuel come out, I have heard vacuum hose but don't know what it is.....

 

What Vader is saying, is that you should check the Fuel Pressure Regulator. It may be bad, and could be causing your fuel problems.

I am not sure how to do this however, I am not very familiar with the fuel injection cars, or I would help to explain what he said.

 

Under the upper half of the intake plenum is the fuel rail assembly. The fuel rail holds the injectors and the Fuel Pressure ReEgulator. You should be able to see part of the Fuel Pressure Regulator by looking between the intake runners (yellow arrow in first photo).

You can disconnect the vacuum line from the Regulator (colored in red in the second diagram) and start the engine. If liquid fuel leaks from the regulator, it has failed. There should be no liquid fuel in that prt of the regulator of the vacuum line.
