IS300 Won't Start!
Today when we went to start the IS, the car initially fired, but then died as quickly as it started. Now it just turns over, but doesn't fire at all. Either no spark of fuel would be my guess.
Can anyone point me in the right direction?

did you wash or rinse out your engine bay recently? It happened to me before and it some how caused a short circuit somewhere. Did you change sparkplugs or anything like that recently also?

It's possible it's flooded.
Here's what I want you to do.
1. Step on the gas pedal all the way to the floor.
2. Turn the key to crank the motor.
3. Keep cranking till you "feel" it's going to start. Sometimes pumping the gas pedal if it wants to start helps.
4 If it starts, just "blip" the throttle to rev the motor to dry out the plugs.

if it do alot of sleeping. maybe its the battery. My car mostly slept through the winter time. Had hard time turning it on, until today i bought a battery and now its turned on fine.

IF the car is flooded. i would remove the sparkplugs and let the fuel evaporate by letting it sit there for some time. while you're at it check your sparkplugs and do some tests to make sure there even IS spark on each plug
(you will need a friend to help u crank the car... Or u can put the key on IGN and crank the car yourself from the starter ( not a wise idea if you've never done that before) haha *works on my 240z*
if its not floodedand there is spark then take off the MAIN fuel deed hose coming from the fuel filter into the fuel rail. once removed from the fuel rail insert the end of the hose into an empty see through 2L soda bottle, crank the car. and see if gasoline is even being squirted into the bottle... PSI should be strong as well. . if pressure is not strong. clogged fuel filter or bad fuel pump is the next step to check. if fuel is good and spark is good then you have an electrical problem somewhere.
hope i helped SOMEWHAt good luck

^^Hey SpeedFan...
LOL...carburators???
I suddenly remember my 81 Corolla SR5. That thing was a BEAST..lol
Yeah, I get what your saying also.
But reviewing a flooded scenario. Sure I know the injectors won't spray anymore as it's program at start up.
My thing is that if his combustion chamber already has too much fuel. Then it needs to match the amount of air coming in to actually give the plugs to ignite it.
X amount of fuel + x amount of air + spark = combustion
But if there is too much fuel and not enough air...No go.
By flooring the gas, the throttle plate is wide open giving it max air intake.
Plus this happened to my sisters BF's IS300(sat for a week) and walked him through it over the phone and she fired up.
