Think she's flooded...tried everything...

88 TII. I'm pretty sure it's a flooding issue, and a very bad one. I've pulled the plugs and turned over the engine and it's still flooded. Tried ATF, still flooded. Pulled egi, and I have a fuel pump switch, but nothing helps. I can get the engine to catch and start to turn over, but then it dies out right away. Is there anything else I can do?

thanks

As far as I know ATF would be no help at unflooding an engine.

If you have tried pulling the egi fuse are you sure you did it right. Pull fuse crank for no longer than 10 seconds, crank again for 5 seconds. Replace fuse.

The last time mine was REAALY bad the fuse trick didn't work. What I ended up doind was just cranking it over with the fuse out. I then pulled the plugs and let her sit for a while. Then I poured some oil in the leading plug holes, turned it by hand a few times. let it sit a minute, replaced fuse and plugs and she statred right up.

The reason you may need to put oil in is that the engine usually will have a very thin film of oil, supposedly one that affects compression. Well when it is flooded really bad the gas will just wipe away that oil. I have heard that when this happens compression drops dramatically, but I have no proof to back that up. All Iknow is that when I did it, after trying everything numerous times, it started right up. Try it, worth a shot at least.

ATF is crap, like you said. Well, not exactly like you said, but yeah anyway.

A way to unflood an '88 automatic GTU was to temporarily clamp the fuel line with a vice grip (and a small piece of cardboard to protect the rubber). As soon as it fired, I removed the clamp and it ran pretty well. This is after removing the Leading plugs and cranking it with the line clamped untill all the fuel had blown out.

Quick and dirty, yes.

The hundreds of people on rotary forums (and probably thousands all over the world, including me) who've successfully unflooded their engines using ATF would probably disagree with you.

It works exactly the same way as engine oil or brake fluid to restore compression sufficiently to allow starting.

I know atf CAN be used, but I always thought that oil was a better alternative to it in cases such as this.

Correct. Engine oil is much better to use because it won't clog your cats.

what i always did with mine before i fixed it, is unplug the fuel pump. this cuts off the fuel but you still have spark. mine never flooded that bad but it would crank for a minute and then catch and then die. plug fuel pump in and it would start right up

my car flooded over at my brothers house, so I had him tow me home with a tow strap. I tried pop starting it while he was pulling me but it didn't stay running, some serious flooding. I'm letting it sit over night with the plugs out, hopefully more fuel will evaporate out.

you could always put in a fuel cutoff switch if this happens too much. Not that I recommend that, seeing as how they can be accidentally turned off while driving, but my brother had the same problem and here's what he did:

1) Put on/off switch in power line to the fuel pump.
2) When starting car leave switch off and crank for a couple seconds
3) Turn switch on and crank till it starts.

Don't know if it will work for you, but it HAS helped SOME people. Basically just makes it so you can "pull the fuse" from inside the cockpit.

PS: I wouldn't recommend this if this is a one-time problem, but if it floods frequently it could help.

For light flooding you can just pull the fuse(or wire in a switch). For heavy flooding I would usually just have to wait it out and put some oil in it. Don't be stupid like I was and spend half the day just pulling the fuse and cranking it over. You'll kill your battery.
