    I just bought this piece of **** and already it won't start. I have to trick it by moving the key back and forth. After sitting for twenty minutes, then it will start. Sometimes when driving, it wants to stall out or it starts to buck. The mechanics found nothing wrong with it but they couldn't get it started either. They said it was the fuel pump relay. Changed that but it made the problem worse. Does anybody have any ideas?

    same thing. it starts for a few seconds then stalls like there is no fuel. put it in gear it dies. can hear a loud whinging sound coming from top of the engine when it dies.

    Same prob also. Car runsfine for a week or two then has this spell were it seems to stall, try to start it and it runs for a couple seconds then dies. After three or four attempts, it will not even start. Wait for 30 minutes, car starts and runs fine until the next episode. Sometimes last just a day, sometimes a week.

    the only problem with the car is that it will start up for a few seconds and then cut off as if it's out of gas. after letting it sit for a minute or two, i crank it up and it starts but often behaves like it wants to stall.

I would say it sounds exactly like a passlock problem. There is a detailed write-up here: . The guy is great, this was the only way I was able to save my Park Avenue.

it sounds like it is starving for fuel, the fuel filter may be clogging up. when a fuel filter gets dirty and cuts some of the flow of fuel, it will stall out at stops. because the engine does not have the proper amount of fuel to keep it running. have a good day !

Car wont run. it starts an cut off

Does the security light flashing after it dies? Will it stay running if you keep your foot on the gas?

It started, when i put it in reverse it died. now it will not turns over and acts like it wants to start but wont. there is gas in it.

Engage the "clear flood mode" by holding the gas pedal to the floor while cranking. This cuts down on fuel delivery to clear a flooded engine. As the engine starts and runs, let up on the gas.

I have a 94 Toyota 22RE that starts fine runs for 45 sec and cuts off. Just replaced the fuel pump and still does the same thing. When I try to give it gas it seems like going to cut-off until I let off...

replace the throttle postion sensor also pull catalitic converter and clean out if it's plugged. You can remove the idle adjust screw and reset it but i would have to give you full proceedure to do that so post here for more detailed information.

Chugs, acts like it's not getting gas once warmed up. Idle's fine

This problem can be several things. When your engine is cold, your computer is in a "closed loop" and just pretty much keeps the engine running until warmed up. After reaching operation temperature, the computer starts reading all the sensors. If one sensor is not connected or is defective, you will experience performance problems. Most of the time this will turn on the check engine light, but not always. Second is the fuel pump. This too will cause erratic engine problems.

Do i have a vapor lock

Remove the gas cap when it does this. If you hear a woosh sound the tank vent isn't working properly. Essentially your tank has turned into a vacuum.
