How to fix a flooded engine?
I have searched but I can't find any threads that involve with the situation I have now.
My FB is flooded, I removed the spark plugs, fuel pump fuse, let the fuel out from the carb then I start to crank the engine. There is mist (fuel) coming out and I know I have to get that all out first before I start to plugging things back on and try to start it. I have been cranking the engine for a long long time but it doesn't look like it's working at all... mist still coming out, my bro poured in some oil in the carb as it was stated in one of the archives. But mist (fuel) still comes out from it, should I continue to crank it without all the stuff or should I try something else? Please help, thank you. |
You are doing it correctly with one exception. You need to open the throttle all the way and leave it there while you are cranking.
I also recommend that you hook up either a jumper vehicle or battery charger that puts out good amps while you are doing this. This allows the engine to spin faster and does not kill the battery. Take a piece of white paper and put it in front of the spark plug holes. When there is no longer anything hitting the paper then you are ready. Also might want to get a fresh set of plugs depending on high old yours are. |
Thank you, Doc. I will try that this coming weekend and see if that's going to solve the problem.

After you get it all defllooded then before you go to restart I recommned either putting a couple of caps full of sea foam down the primary barrels of the carb. Or just spray some starting fluid.
|
+1 for starting fluid. also make sure your plugs are dry, or just throw in a spare set.
|
Ok, I will do that. Thanks guys. I will let you know if I have any more questions.
|
What has worked for me the last few times I've had to deflood, is just dump about an ounce of Seafoam down the primary barrels and then she starts right up....
|
Clean your plugs, why do you think they aren't firing? The engine can be bone dry, but if the plugs are still wet, it won't start
|
+ 1 and maybe he is trying to start it with a weak battery.

Update!
Hey! I have an update for you guys. I did what Doc and whoever told me I should crank the engine without the plugs, fuel pump, etc with my foot on the gas. It worked... started right up... I cranked it with the jump cable on. Car started fine for the day, however, today when I was about to start it again... didn't work! Lucky that my driveway is a slope so I put it in reverse and let it roll and started right up... voltage was at 13-14 when after choking/warmup... what can that problem be now? Since the voltage is 13-14... it's not the battery's problem... I have the S4 alternator... what should I be checking? :)

Make sure the cables and posts are clean on the battery. I recommend that you have the battery load tested to verify it's cranking amp condition. If the engine is not being turned 240 to 250 RPM then you will have a starting problem.
Also make sure the grounds are clean and the connections are tight at the battery and at the starter. Once you have gone thru all of that if there is still a problem I would recommend performing a compression test. |
I am sure the posts and cables are clean because they were just replaced like 2-3 months ago. I should be checking the starter's connection, if that doesn't solve the problem. I will be testing the battery's cranking amp.
Thank you, again. Doc. |
I would be leaning towards having the battery checked before all. :-)
|
Ok, that should be done throughout the week. Thanks! =D
|
Does it SOUND like the starter is turning over with normal speed and vigor? You should always listen to the starter when your car is starting and working OK so you have a mental reference.
|
I had it tested a few months ago, it's fine. Should I take it out and see if it's okay now?
This morning, I was going to drive it to work... car wouldn't start unless I jump it. The battery seem to be the problem now... I will find out tomorrow as I bring it to autozone to get it checked. |
SO many times I've found that a hard starting car simply has a lot of corrosion on the battery terminals. One of those $4 plastic combo ID and OD brushes from the auto store solves the problem.
|
Battery cables are new and the battery sure is clean though. I had all that checked before I plugged them on. I will check the cranking amp.
|
Better go back to looking at that alternator by the sound of things...
|
I'd recheck the battery. Did you buy it new or is it an old one, and if so how new?
If the battery is kaput it may hold a charge after running the car for a while making you think it's good, but then die off after a few hours, hense your having to boost the car. If possible swap in a known good battery. Always try the simplist things first. |
The battery is old, not too old but I did tried to crank the engine with it before so it's probably doomed. After school today, I will be checking those out. I am leaning on the battery's side.

You can buy a small hydrometer (hygrometer?) at the autostore for about $4 that allows you to test the gravity of the fluid in the battery. The one that I have has 4 colored balls in a small glass column and is filled by drawing fluid with a bulb at one end. When mine floats 3 or 4 balls the battery is good. You have to test each cell since a single dead cell can kill the whole battery. This is an excellent way to test a battery.
If the battery tests good, then you may have a bad contact in the high-current starter circuit. In my experience, a voltage drop as low as 1.5 volts can kill a starter. I use an old D'arsonval (mechanical movement with a needle) movement low voltage meter (haven't tried a digital for this) to check across the two battery terminals, which is usually where the problem is. Flush out the tester with tap water before storing it away. |
Try this; turn on the headlights, then attempt to crank the engine over. Do the lights dim? Post back with results...
|
I couldn't even crank the engine more than once if I don't jump it. It would crank once and go errrrrrrrrrrrr and won't go again. But when I jump... it works.
|
Your battery is toast, get a new one!
