It may be due to a failed/faulty fuel pressure regulator. I had this problem: easy start when cold, hard starting when warm/hot, and rotten egg smell from exhaust when warm/hot. My mechanic diagnosed a failed/faulty fuel pressure regulator, replaced it, and now the problems (warm hard start, smell) are gone. I have a '92 GT with L4 engine.

Go over it, check the air filter, fuel filter, make sure your key isn`t bent. bent keys off set the chip and the car cant read it. next time take out the key and turn it around and try it again. let me know.

Car stalls while driving. Will start after about five minutes. Is not flooded. Doesn't usually do this until after it has been driven a bit. Does it more in warm weather. Check engine light sometimes...


I'd have fuel pressure tested. I had a 95' did same thing. Cold winter day, worked fine, as soon as it got warmer, or hot out, it would quit, and re-start 20 minutes later and go for a distance then die again. If I parked in the shade on a hot day, I'd get further before it quit for the first time. I started carrying a fuel pressure gauge with me. Cool in the morning my fuel pressure was up to spec @ 49-50psi. Once it got warm/hot out and it died, Hooked up gauge and it was at 2-5psi. Let it sit and cool off 20-30 minutes, pressure would jump back up and run good until fuel pump got hot again and then pressure dropped off and car quit. It sure sounds like the fuel pump, but the hard part will be getting the car to the shop at the right time, or they will need to let it run on the lot until it quits to confirm the pressure drop. One thing you can try is when car quits, have a can of WD-40 or quick start with you and a screwdriver. Loosen the clamp on the air intake hose where it connects to the front of the throttle body and pull it off. With vehicle off, turn throttle linkage so the plate opens up enough to spray WD-40 a second or 2 in the throttle body. Then try to start it. If it starts and runs momentarily, then you can be pretty sure it's fuel related and my guess is the pump needs replacement.

1990 toyota celica fuel problem. It appears to be flooding. When cranking, if it has been sitting for a while, it fires for just a second, and then dies. When the fuel pump is unplugged, and engine...


start with trying to start the car with your foot hard on gas pedal, all the way to the floor this will stop fuel flow on start up its called clear flood mode. as the engine starts to fire and run ease off the pedal until it idles, it may take some time to run smoothly. if it doesnt run or stalls after a short time and then will not run i would try a ECU engine control unit as it supplies the earth circuit to the injectors, may be thats whats holding them open or they are dribbling badly and require overhauling

this sounds like a bad starter, im not sure of the syptoms, but when you turn the key if nothing happens then its a bad starter next time it doesnt start try tap on the starter if it starts then its a starter.

2005 mazda rx-8 automatic will not start


Does it actually crank? If so and doesnt start then its probably flooded. Been a problem with those cars since they came out but not to feel bad theres quite a few cars that flood easy do to certain sensors. If not turning over but just clicks then battery issue just keep in mind every time try to start and it doesnt that more fuel enters the system and doesnt burn off which means more flooding (to much fuel)

Car cuts off while driving will not start til after it sits for a few minutes


It sounds like it may be a fuel filter. When the engine is running there is a vacuum created to send fuel to the engine. If there is dirt in the fuel line, it soon blocks the fuel and the engine will die. After the car sits and the vacuum is released, the fuel will flow again until it soon plugs up. Replace your inline filters. It is an inexpesinve fix. If that doesn't work, it may be the in tank filter, you will need a mechanic to replace in tank filters.
