De-flooding isn't working...
 

I recently bought a 1985 GSL-SE with a 13b that is completely stock afaik.

The car was having an issue with "drinking" coolant, and while a friend and I were tinkering trying to figure out why coolant was disappearing we did the unthinkable and shut the engine off without letting it get to operating temperature.

At that point we had a flooded 13b.

We spent the rest of the evening attempting to fix the flood problem using the fuse method but ran into some problems and never succeeded. Our first problem was locating the fuse that needs to be pulled to shut off the injectors. We found one near the steering column that seemed to do the trick but all the guides I could find said it would be near the battery in the engine bay. We couldn't find any fuseboxes in the engine compartment... And I can't seem to find pictures of the box that is being referred to. Does anyone have one?

So after that I do some more research and find the method that involves pulling the plugs out and flushing the housing that way. I tried that for about 2 hours, trying it with the fuse from yesterday pulled. Then I found what I believe is the fuel pump connection behind the drivers seat...but again I'm only kind of sure that it's the right connection....can anyone give a good description or provide a picture of the easiest way to disconnect the fuel pump?

So here I am now, having tried all the de-flooding techniques I can find here and elsewhere on the internet and still without a running motor.

The compression seems to be fine, as it spews clouds of fuel when I take the plugs out to empty the housing...The spark is good on all connections...It's getting fuel, and seems to be getting to much...And the heating problem I believe is unrelated as it was never overheated, and the symptoms indicate a bad radiator clutchfan.

Any advice? I'm about 10 minutes away from pull starting the damn thing...Which I understand is asking for catastrophic failure...but I'm starting to get desperate as I need to get this car running soon.

easiest way on that car is the connector under the drivers side bin. its a white connector kind of t shaped and has i believe 2 wires. remember to only turn it over for about 10 seconds at a time or you can overheat the starter. pulling the plugs speeds this process up, but im not which fuse or relay to pull to cut the spark plugs so you may not want to spray fuel mist out of there with hot plug wires close by.

cant take a picture right now, but if you think you find the connector post it up and i can tell you. also, pull starting it is not going to work if its flooded.

Yeah, pulling it did no good at all. Didn't even try to fire...

I'm going to start again tomorrow, for now I'm in for the night.

Not sure if your SE is like my 82, since I hear that if you disengage the fuel pump you won't crank. Correct me if I am wrong.

This is how I deflood my 82.

Under your dash you should see a fuse block with fuses that look something like this:

The one I circled is your fuel pump fuse. Pull it. Now you will have no worries about fuel getting into your engine while you deflood it.

Remove all your spark plugs and start spinning the motor over. Spin it over for about 5 seconds, then wait a minute and repeat it again. You should see some fog/mist come out. That would be your excess gas. Let the engine "dry out" with the plugs off. While the plugs are off, kind of fling them around and get the excess gas off. Use a butane torch and burn them if you want to clean it. I take some carb cleaner and a metal brush made for cleaning plugs and go to town. When your plugs are clean, spin the motor over once again for 5 seconds, reinsert plugs, put wires on correctly, and reinsert fuse. That should do it, atleast for me.

Ignore the horrible wiring the previous owner did to try and put in auto door locks.

One thing I can spit out is to mention that if you are using the same plugs they might be fouled pretty bad, clean them, or new pair if you haven't already. I had a se that I put a switch on the injectors. Its a good hour or so away from me in the country and my Grandma's, If I can get out there ill try to find out what I did... been awhile, rx-7 is cut in half (not my doing), long story. r.i.p.

Sorry, can't control being a smartass.

he said it in a diff thread but he didnt wanna be so obnoxios as to have it link to the search page lol and just as a bold reminder for people to search

The fusebox on the 82 posted earlier looks identical to mine, although I've been pulling a different fuse...I'm pretty sure I had the wrong fuse, but when I disconnected what I think was the fuel pump the mist went from heavy to non-existent. So I'm pretty certain I have the "get the extra fuel out" step down...What am I screwing up after that? A friend suspects a stuck injector, and if I can't get the problem resolved in the first half of tomorrow I'll pull them out and see what's up.

What I've been doing is clearing the housing of fuel, putting the plugs back in, hooking my fuel back up and then cranking the engine with no throttle with no success.

Help...:(

I have an ultrasonic cleaner where I used to work. Do you need to get your injectors cleaned?

Well I haven't taken them out yet so I don't know...In fact I don't know how much new ones would cost let alone cleaning them, haven't looked into it just yet as the idea of a stuck injector only recently occurred to me.

Touché :)

As far as ultrasound cleaning goes, if it is just put it in some cleaner and in an ultrasound booth I can do that for ya.

mine only starts after i pull and clean the plugs and squirt a little oil in there to get some comp. back

Okay. First let me restate some of the things that have been said. Pull the fuel pump fuse OR EGI fuse with plugs out AND SAFELY AWAY FROM THE EXCESS FUEL, and crank over. Clean and dry plugs or install new plugs. Put said fuses back in and start. Pull starting it will not lead to catastrophic failure. Not sure where you heard that. If coolant is dissapearing and you see no leaks from the cooling system, unflooding the motor is the least of your worries, it's rebuild time

First, buy new plugs. Once you foul them it seems they never come back to full strength again.
If you can get a little oil in the combustion chamber it will help.

And, I agree with the post above. If you are leaking coolant in to the chamber, your engine is toast.

I never found the EGI fuse, I ended up disconnecting the fuel pump. Since then I've been able to deflood by giving it 100% throttle while cranking.

I burned all the oil and gas off with a torch and the plugs were spraking just fine so I left them in. And the coolant isn't leaking into the chamber, as there is no white smoke and all my coolant is squirting out of my overflow.

I suspect the coolant is just boiling and getting hot enough to blow into the reservoir, but it just keeps doing it until my add coolant light comes on. I'm not sure if the system is trying to burp or if I need a new radiator or if the jackets in the housing are clogged with rust. Can anyone give me the quickest and easiest way to flush both the engine and radiator coolant pathways? Preferably without taking the flexfan I just installed off, as it's a bitch to get on. I was thinking of taking out the thermo and trying to blow water through the system backwards, is this feasible?
