    I have the same problem just want to know if the vapor locking by loosening the fuel cap to vent and unplugged the line.

    Did this solve your problem? If not, what did it turn out to be?

Why does my 93 Honda Accord run fine and then dies going down the road and will start again and die again?


There is a black fuel relay way up under the top left driver side dash that breaks its main wire solder connections on the circuit board under over-heat conditions. Resolder that relay. Starting fluid will show that you have lost fuel delivery under no start conditions. You can use the breather hose from the valve cover for this test.

97 lumina, 3.1. Starts runs smooth, drive for 30


I just recently have been fighting the same problem with the same make/model/year vehicle. For myself, I would drive off and on through the day and it would run fine. Then suddenly after a start it would run rough and die. I would have to wait 20 to 60 mins before it would start again. I had it checked and fuel pump was only putting out around 19 psi. It should be around 41 psi. Had fuel pump replaced and no more problems. Furthermore, now it runs so much better. It's funny how over time I didn't notice how the performance was slowly degrading. Unfortunaley fuel pumps for this car run around $300.

2000 Grand AM GT Shuts off while driving


What you should do is check for spark when the vehicle stalls.If you have no spark then you probably have a bad ignition module.The other thing is You didn`t mention if the check engine light is coming on.If it is then have the codes read.Even if it is not you should still check the codes.Sometimes the computer will have a code and the light will not come on.This could give you a clue as to what could be causing the engine to stall.You might also want to check your fuel pressure just to make sure it is good.The pressure should be 52 - 59 psi.Hope this helps.Good luck.

Car shuts off while driving


if car shuts off while driving it could be a bad crank sensor. a bad crank sensor will shut car off while driving, then it will not start for about 10 minutes, when it starts it runs fine until it goofs up again. the popping could be the sensor for it controls timing along with the cam sensor.

Sounds like fuel pump quit, do a fuel pressure test to make sure. Thats the way they act when there going to quit all together. most likely after you fill up the tank with gas.
