I'll take that as a "no", then. Check the battery.

i would check the electicals, see maybe the boot of the spark wire came off the plug or is loose..check your coils..check fuses and relays..sometimes its the obvious that will make you go insane..

Has it ever been overheated? How many miles? Ever ran low on oil? Oh and check your plugs, or even just replace them.

never overheated. 50k on the motor, oil level is good.

i don't think its a electrical problem... wish it was. you know more about the car than i do, could it really be the main fuse?

i just tried started it yet again, there's white smoke coming out the muffler long as i try cranking, not super heavy, but its pretty noticable.. for 3 seconds the motor did seem partially start, but when it did it wasn't the usual VROOOM sound it was like a weak turn turn turn..

could the engine be flooded?

Let me be the first one to throw in the obligatory "Check the vac hose on the map sensor"

Also, try to hold the throttle depressed all the way for a few seconds while starting the car. That'll cut of the fuel supply and might clear out the combustion chambers if the car is somewhat flooded.

Good luck.

spray carb cleaner in the intake manifold and see if it starts. If it does you've got a fuel delivery problem.

Its Fixed

thanks to all of you i have fixed the problem. i killed my battery cranking the motor, took 5 hrs to charge it back up, cranked again.

looks like it was a mini-flood. there was plenty of white smoke coming out for a few minutes but i didn't need to use wd40. the motor took care of the excess fuel.

glad you got it fix but what made you go back to the battery and saying the battery checks out? well i guess if the cranks were getting slower and slower..

do you have a multimeter? thats a given right away if you have one to know if its the battery or not..

yeah i originally used a multimeter to check the voltage. it was checking out right around 12.4v.

it was cranking hard and the interior lights worked at first... after jumping on the forums and back and forth to the garage, the cranks started getting weaker, the open-door beep started sounding funny then finally the interior lights wouldn't turn on at all.

so i basically killed the battery with the cranking. once it was charged it took just a few more tries to get the motor started to burn off the excess fuel. it idled weak and rough for a while and continued to shoot huge clouds of white(?) smoke out into my driveway for a while and it smelled pretty damn bad, haha. shoulda seen the grin i had on my face for the next 10 minutes as i cruised around the neighborhood

12.4 is pretty normal for a battery, im wondering why it didnt start then..

are the terminals to the battery loose by any chance?

the terminals were pretty tight.

after checking volatage i checked the battery fuild levels, which were okay. i think it just didn't start cuz of the little amount of flooding i mentioned

today new are sparks are going in

The plugs on one rotor were fouled. That's why it "wobbled" - it was only running on one rotor.

Like others have said, you probably have a coolant seal leak. Residual cooling system pressure forces coolant past the seal into the chamber after the engine is stopped, which fouls the plugs. Then it's hard to start. When you get the leading plug on that rotor dry enough to spark, you get it running, and the coolant in the chamber produces white "smoke" (vapor) out the exhaust.

Certainly replace the plugs, but don't be surprised if it happens again. To prevent the plugs from fouling, the next time you go to turn off the car, rev the engine to about 3000RPM and hold it there for a couple seconds, and then turn the key to stop it. This warms the plugs enough to evaporate most of the coolant that makes it onto the plug after the motor stops.
