I posted last week about a flooding problem and I got some good info. Might be a stuck injector. I pulled the injectors and had them flow tested and cleaned. They could not be in better working order. I have spark, so that is ruled out. ANY IDEAS WHY ITS STILL FLOODING? Has anyone run into anything like this before? The injectors were also tested for leaks and nada. Im at my wits end with this car. I have taken the upper intake off twice now and its really starting to suck. If anyone has any ideas about what might be going on with my car, PLEASE post! Could it be a short in anything? A computer problem? I will tell the story for those who dont know. I started the car one day and it ran great, better than ever since I tuned it up with new coils, wires, cap and rotor, the works. Then I open the actuators for the 6 ports and try to start, and its been flooding ever since. Opening them has nothing to do with the gas or injectors, but is there anything I could have bumped? Seriously, it was running, I went inside to get a bite to eat, then opened the 6 ports and it has been flooding ever since. Thanks guys.

You don't have the Sleeves anymore in the ports??? It might have cause the ECU to re...something and its dumping more fuel.... due to that extra air....

If not I was thinking about your fuel pressure, but if didn't flood until you opened up the 6 ports...

Vacuum leaks.... could be....

 

Can you get it to start at all? mine flooded awful when I put the new motor in it ,with the sleeves removed. I thought something had gone wrong with the ECU. I wound up pinching the fuel inlet line off with a long pair of needlenose until it started to hit, it eventually fired off and has been running fine ever since

 

if its flooding... take a slant nose vise grip and clamp the fuel inlet hose and crank your car... let it catch and when it does hurry up and take the vise grip off...I had to do this a few times on my SE when I got my rebuilt.. low compression on a new motor..seals had to set..I leave my vise grips in the car for just in case situations such as flooding.. another route would be to put in a fuel cut off...rechect and double check all the vaccum hoses..

does the car turn over when you crank it? are the plugs wet when you pull them out?

 

You AFM door might be stuck open causing it to flood. Check it.

Either that or test your fuel pump (See if you are getting the right PSI).

Did you buy Mazda replacement parts? (ignition and rotor, spark plugs?). Too many possibilities. If you can comment on these things so we can help you further.

 

I will have to try the vise grip thing. Yes, I have to shake my plugs on a rag to get all the gas out. I even shut off the injectors, cranked it with out the plugs in to get all the gas out. Then I did a little atf, put the plugs back in and tried again. It fired for about a half second and flooded again. I got my injectors back last night. Im going to put them back in and try the vise grip thing. I will let you all know how it goes. And I will check all vaccume hoses.

 

I haven't read the whole thread but I know that it's really hard to get the car going after it's been majorly flooded.

Here's what you do, you'll get it started no matter how bad it is. get a friend and tow the car up the street but meantime you are inside droping the clutch in 2nd gear (with the key in the "on" position). if you can get it to 10 mph then do it you should get it no prob. It'll smoke and run rough for awhile but you won't have anymore problems starting it after.

But you shouldn't have put any atf in the motor. That might complicate things.

If you were "vise gripping" the fuel hoses be carefull that you hoses don't get damaged. Cause that's a crazy engine fire if it leaks and ignites.

My suggestion hide those vise grips and don't use'm around your car anymore! LOL

 

Well, Im going out to put the injectors back in and see if it starts. If it doesnt, I know how Im going to fix it. Ill just bolt on a 48mm webber ida. Which I will pick up tomorrow if it does not start. Thanks for all the help.

 

I haven't read all of the posts, but try checking your AFM, if it's disconnected or stuck open it'll flood like crazy.

 

Lol, the way you wrote the subject of your post, I thought you were saying that the GSL-SE people need (mental) help!

Just goes to show what late nights do to ya!

 

Ok, first gsl-se Ive ever owned, first rotary with fuel injection. At the risk of sounding retarded, what the hell is the AFM? What does it do? where can it be found? Sorry, Have been running a mikuni on a 12a for the last 4 years, not fuel injection worthy yet. I might skip the webber, found a T2 motor, complete. How hard is that to put in? But still tell me what the AFM is. That would probably be cheaper and easier than a T2 swap.

 

The fuel injected cars such as the SE and second gen. Do flood occasionally if you do not let it idle a little before you shut it off. If all your other trouble shooting leads to nothing it is very common to put a fuel cut off switch in. You turn it off when starting the car allowing any gas already injected to start the car, then as the car starts turn the fuel pump back on. I had a GSL-SE that was great, after I rebuilt the engine I needed a switch, this is not uncommon at all. If you do not know how to add a switch, a mechanic can do it or someone here could explain im sure.

 

The AFM (Air Flow Meter) is located under the air filter in the black box at the front of the engine bay on the passenger side. The AFM measures the amount of air entering the engine and allows the computer to determine how much fuel is needed.

I am having this same exact problem with my SE. My problem occurred over a period of time. The car ran richer and richer until it would no longer run. I wasn't able to get the car running and is sat for a while and developed cabon lock. Anyway, I got that problem taken care of. I am still getting flooding like you though. I thought the same tyhings like leaking injectors. They turned out to be fine. I then checked to see if there were any error codes on the ECU and it turns out that it was showing an AFM error code. So now I am getting a used AFM from a forum member and I hope that will take care of the probelm. So check your error codes, maybe you have a problem with the AFM also.

My car floods every now and then. It doesn't really flood in the winter at all, just mainly the summer. I will TRY (it doesn't idle well) and let it idle a little before I turn it off. If your car ever floods and you need to try and start it unplug the engine fuse and turn it over a few times. Then plug the engine fuse back in and it will start. It's worked for me everytime. (This is off topic but the yokohama es100's are awesome, they grip so well, I love them, )

 

You can pull that fuse but, it will eventually break and it's a pain to keep lifting your hood. The fuel cut switch is easier and more reliable.

 

Cool, air flow meter, DUHH!!!! I should have caught that one. So now onto to T2 swap, is that pretty hard? I did some alarm work at a fellow racers house and in trade he wants to give me a webber 48 ida carb and a complete T2 motor. You know, turbo, intake, computer, the whole works.
