Customer Question

Hi Tom
I have a lengthy story line to my 4 runner issue. Purchased a 99 4R, v6. Ran fine initially. 2 weeks into the purchase the fuel pump croaked. Replaced the fuel pump along with a new fuel filter and a new air filter. The tank had about a 1/4 tank of fuel during the pump replacement. Drove to the station to fill the tank and added fuel to 3/4 tank. Car ran fine for about 2 miles. I got home and noticed gas running out of the bottom of the Charcoal Canister through a rubber line that was affixed to the car frame . Removed the Gas cap and the fuel stopped running. I drove the Car and ran out that thank of gas without a gas cap. Of course the engine check light came on. Refueled the car and replaced the gas cap with a new cap from Toyota. Drove a few miles and the car started hesitating and stalled out. Fuel was again running through the tube from the Canister. Removed the gas cap started the car and it ran fine after a few sputters. Drove home 10 miles and noticed that the check engine light had gone out. Once I reached a half tank the next day the check engine light appeared again. I put the Gas Cap back on and after about 2 miles the car began to sputter again. So I removed the Gas Cap and the car runs fine. I made the pump repairs myself. All the lines are correct. The fuel filter is located properly. Thinking I may have a solenoid issue inside the canister or perhaps a pressure sensor fault somewhere. The local parts store checked the engine light and they say it it the catalytic converter. Thanks for your help.

HI I believe its going to be a faulty EVAP system vent valve on the tank that is supposed to be preventing fuel from getting in the line that sucks up the fuel tank vapors.- - It may take me 1-2-3-etc... responses to get the information I need resulting in giving you the answer you need. I can't read minds nor have a magic wand, & I'm not there to see, smell, feel, or hear so I need good information to return a good answer. My normal hours online are 3pm-3am. There are 2 services your receiving 1: from Just Answer whom has already collected the deposit/question value 2: from me (not an employee of the website & have no control over anything except what I type.) You will be asked to RATE THE SERVICE, your rating me, my response, not the website, rating has no effect on your payment, and it DOES NOT close the post. A rating IS REQUIRED, if you can't complete the required rating today, let me know why so I can get you exactly what's needed.Thanks Chris
