Car won’t start and I know why but... (Kinda long)
 
Car won’t and I know what the cause was but I still can;t get it to start now that it is fixed...

I took off the Throttle Body elbow to give me a better view of a small oil leak I gave around the Oil filter pedestal. I put it back on and go to fire up the car. It starts but the idle is very low and very rough. It ended up stalling. After that I couldn’t get it to fire back up. I figured I flooded it somehow so I try the gas pedal all the way down trick but after many attempts I couldn’t get it started. I decided to see if anything was wrong under the hood and sure enough I notice I had knocked off the hose for the MAP (boost) sensor. Damn it! So while this was the reason it was not starting (and not because it was flooded) I am sure it is now flooded after my several attempts to start it.

So I hook up the hose and sure enough still wouldn’t start (as mentioned above must now be flooded). I ended up having to remove one plug from each rotor remove the fuel pump relay crank it to get the fuel out. Put everything back together and fire it up. It starts after three attempts or so but was still idling rough (I read this would happen after the motor was deflooded). Went into the house to grab something and when I cam back out the car started to idle very low and then stalled. Tried to fire it up again but no luck. So I removed one plug from each side again, cranked and put everything back together but the darn thing would still not start.

So with all that said... is it common for it to be this hard to start after flooding? Is there something I am missing like, does one need to replace the plugs with new ones after they flooded the motor?

Sorry for the long story. Any help is appreciated.

Im pretty sure if you remove your plugs they will be soaked, so try new ones just so u can eliminate that idea. Also if worse comes to worse pop the clutch?Some one will chime in here with more ideas im sure.

Ya, the plugs were really wet both times I pulled them. Cleaned them up but as stated above no luck after the first time. I guess I'll just try everything over until it works.

whenever you flood an engine you should replace the plugs. they are fouled and won't spark very well, givign you a rough idle and hard starts.

Also you could try the ATF trick. Just put a small amount into each rotor housing through the plug holes. The atf will mix with the gas making it a thicker liquid, that is more likly to be picked up by the apex seals. Then turn it over with the plug holes open and the throttle all the way down. Do this for at least 3-5 minutes. Replace your plugs and try to start.

And what does poping the clutch do for fouled plugs ? ? ? ?

In some cases when the plugs get fouled there is no getting them to fire, even after drying them and reinstalling them. New plugs should clear up the problem with both the hard start and rough idle.

Just FYI, the MAP sensor not being plugged in won't keep the car from starting. The car will start just fine, it will just run like crap. ;)

As for the car being hard to start after being flooded? YES!

Sometimes it takes people a few days to get the car started after being flooded. I just delt with this last week and it's not fun. What you need do is follow these steps:

Also, keep the battery charged as trying to crank the car this much will begin to drain the battery.
