Flooding- I've already looked it up
 

My Question is for my 84 12a. I have read all the posts about our vehicles flooding and how to unflood. I looked it up on google and there was a specific "Tech" how to.

As you can tell I have a flooded car and cant seem to get it started. I read though the how to and I realized that it said for the 84-85 13b. I also couldent figure out what the Blue Blade Connector was. there was a picture but it didnt load so im guessing...

Will this three step procell work for my RX? Or do I have to find another fourm. I did a search for Unflooding but it said no match was found. I know you guys have probably had this same question a million time but I really have searched and this is all I have come up with. Sorry

Your right we actually should have a FAQ for this its so common. I looked as well and didn't really find anything easily.

If you car has flooded make sure the cause is known and fixed.

Then remove the sparks plugs, clean them with a spark plug cleaner or sand blast em or hit them with some solvent ( brake cleaner is a fav) and a brush. Just make sure they are clean and dry.

Leaving the plugs out, disable the coils by pulling the fuse for the ignition.

Now crank the engine until you no longer see a fog or mist of gas/oil escaping from the plug holes. Mind you, make sure there is no spark source while doing this as the gas/oil vapors are very combustible. See disabling the coils above. This should only take about 10 seconds of cranking.

Now put the plugs back in, renable your coils and start it up. Lather rinse and repeat. Sometimes it takes a few tries because you haven't fully fixed the flooding condition.

The common cause of a flooded engine is to turn it off while its still cold. This typically leaves a rich mixture in the chambers and will cause it to be hard to start next time and maybe flood out. So always wait to shut off the motor until it has completely warmed up. If you follow this rule you'll have better odds of not flooding your engine.

I blow off the plugs with compressed air, then I blow air into the plug holes, and I do the cranking thing also, but that never is enought to get mine to start, I also use those spacers you can get from auto parts stores that move the spark plug away from the fuel stream. I think they're called spark plug non-foulers and they are in the assorted parts section of auto zone or somewhere like that. I carry these and a plug wrench and a spare set or plugs with me at all times. once you get it started, then you have to turn it off and re-install the plugs without the spacers
you might also try a new set of plugs.

WTF????

also make sure you have a crankcase full of fresh oil, and try to start the car with the normal procedure of choking it all the way, but you may still need to use the pedal to keep it going if it fires. and you may need to mess with the choke also to kjeep it going. have the clutch pedal down to lighten any load on the motor while starting also.
once it fires you'll have a gigantic outpouring of blue smoke for a few minutes, then it will run normally
gook luck!

i have done that all before to deflood our 7's, however i have also found that you can pour a small amount of ATF down the carb and that will help build compresion and aid in starting the engine. I have also had to tow start the car in second gear when our first 7's engine was quite worn out.

I agree with blown7, nothing works as good as a good tow in second gear if you've got one that's giving you trouble. I usually start with the deflooding ritual, but half the time it doesn't work and I end up towing it anyway. Next time I think I'll just hook up the tow chain and try that first.

I've never had a 7 flood that bad on me. Just lucky, I guess.

If the spark plugs look a rusty brown on the center electrode, you need to replace them. Tip of the day learned the hard way.

For fun, you could pull the air cleaner lid, use a big screwdriver to hold open the secondary throttle plates, run jumper cables to someone's car and then have someone spray Gumout's Carb Cleaner (or Pyroil's Starting Fluid) at the air cleaner base while you spin the engine, foot OFF the accelerator pedal. This worked the two times it wouldn't start in the cold with the usual pre-pulling-the-spark-plugs flooding routine I had. On the third time when even that wouldn't work, I just changed the plugs.

Problem solved since then.

:cool:
