I also forgot to mention there is spark, and fuel present.

FLOODING

KFelkner02

Well, I thought that and I tried the unflood, method, and it seems like the car wants to start a little better but doesn't actually start, I have put a little ATF in the plug holes also, and no difference.

TheBigOne

mine flooded real bad once.

I just kept the starter going. the battery died but i pulled the one out of my caddy and kept goin. it finally started.

it all happened cause my inside light was left on and the battery was weak. injectors still shootin but too slow of a rotation to start the car.

I agree with your alarm. The burning of grass.. where under the car? If up front then maybe, just maybe, you have clogged cat(s). If you had it running a while and they (or one) super heated that would be your burned grass? That (clog) may explain why it wont run. Not sure how injector cleaner might be the villan so I won't offer any comments on that.

Good luck.

Well, I took the cats off, and gutted them, still same thing, but it doesn't seem to be burning the grass now. But it does still smoke real bad, when starting up, it smokes by the o2 sensor, area, and by the air intake manifold. Then later after the engine warms up it seems to pour smoke out on the Drivers side of the engine, right under the Dynamic Chamber. I have also changed the thermostat thinking that it was maybe the culprit. I'm new to 7's but the Temp was running about half way on the stock gage, and I noticed that when I felt the coolant hose going to the BAC I noticed it felt like it was boiling, so that is the reason for changing thermostat, but still no change. I can't tell if the smoke smells sweet, it really isn't anything I have smealt before, but it is white in color. I think I just might give up on this car. I have spent my whole summer on this car, and all of my Graduation money on it, and now I do one little stupid thing and it doesn't run anymore. Anyway thanks for all your help.

That sounds pretty frustrating.

I would do a compression check on the engine.
If the engine is no good, you know where you stand in terms of where the priorities are.

If engine is good, then you'll probably feel better, and there is a good chance it is a relatively easy fix.

I think you have blown your engine that is too much smoke for it to not either be blown or damn near close to it.. compression test and watch the rear rotor go to a higher place in rx7 heaven

It might be possible that you had carbon build-up and the additive loosened some. Or a lot and it messed with your seals and cats. (Sounds like a 'nature show'!)

I would check the condition of the cats. Rap on them with a rubber mallet and listen for rattling. I had a loss of power after adding Techron, but it turned out the 'catalyst' block had shattered and plugged the entrance to the 'y' pipe.

If the Lucas stuff did it, odds are the motor isn't blown.
If it didn't do it, the motor may be coincidentaly blown. Maybe.

Get a new set of NGK plugs. Take the old plugs out, pull the EGI fuse, then hold the accelerator to the floor and crank the engine in 15 second intervals a few times to blow some **** out of the motor. Listen to see how it sounds. It should have a chugging sound and have someone put there hand in there to see if its pushing air out of the spark plug holes. Change the oil, throw the new NGKs in there,put the EGI back in, and fire her up. That should fix the problem.

Thanks, maybe I will try these. I was sitting here thinking and I did a little more research, I think I might have found the problem, maybe. I'm wondering if from putting the Fuel, treatment in made my engine run hotter, and since I thought possibly already that my cats, might have been clogged, it made it overheat, and burn up, the water seals, which is making coolant leak into the chambers, and make the smoke, it's just a thought but tomarrow, I'm going to see about getting the coolant system pressure tested. I'm sure the apex seals are fine, the car seems to start fine, and has nice whoosh, whoosh sounds coming from the plug wholes. I checked all the plugs, and wires today, and found that all of them sparked.

I am telling you!!!
unplug your BAC.
Change your water temp sensor ion the filler neck. if it still won't start change the air intake sensor.
I fought with this problem for a month and a half. After I did these things in that order is never did it again.
what is the use of useing the forum to get insight if you don't listen?

And that beeping that starts after 10 seconds is your p/s computer warning of a fault. It has nothing to do with your engine probs... Check out this big-*** thread if you want to follow it up later...

Well, I tried Tweaked's idea, of taking the intake hose off, and all it did was make it stall out, I'm not sure what that means. Anyway, I was reading about o2 sensors, and so I figured this might be one of the problems, it looked like it hadn't been changed ever, well I unplugged the sensor, and started the car, I expected it not to run at all, but it still, ran the exact same way, so I am in the middle of replacing the sensor, I should have it all back tomarow so hopefully, it fixes it.

The wire on the old o2 sensor, and the connector on the engine wiring harness, was so brittle the end just fell off, so I am directly wiring it on without the connector, if this does not fix it, I think the next thing would probably be the water thermo temp sensor, but I'm not sure this would do it, even though the gauge still reads, temp.

Also when taking the dynamic chamber off, I noticed that the vac line to the fuel pressure regulater, had either been off from the start off my problem, or it came of when trying to get the chamber off, but I was wondering if anyone knew, if this vac line was not connected would it cause the same symptoms?

Actually, I'm pretty sure it is not from that, because it never done this beeping, when I had the car running fine, and also they say, it is a 5 beeb, pattern, where as mine is a constanst beep..pause..beep..pause..beep forever until i turn the ignition off.

The p/s beeps vary depending on the warning from the p/s computer (1-5 beeps.) Check out the downloadable FSM from www.iluvmyrx7.com.

you likely cleared out alot of deposits in your engine(fouled plugs).

maybe you had a tonne of buildup on your housings that got cleared out. if you did your springs are prolly weak and not compressing the seals worth a damn. are there alot of detergents in that stuff?

did you notice alot of smoking when this happened? that would be a clue. if not, it may be something else.

look like your screwed either way

KFelkner02

Well, I finally got the engine to run properly, I was searching about the it having a varying idle, and I decide to unplug the tps, and sure enough, it ran lots better, so I plugged it back in, and adjusted, it and the air adjust screw, now I have a near perfect idle, and no smoke, at least until, the grass underneath starts smoking, I have no clue why this is doing this, but hopefully, I will have it in the driveway. Although most of the problems, have been fixed, except for one. It does the exact same thing, now that the car did from which this engine came from, it wants to stall, out once you put it into gear, it moves for a few feet, I'm sure it's not the engine, because it ran great until, now, is there anything that could cause the Torque converter to go bad, I did not use the one from the other car (the one that had this same problem) for fear if this happening incase it was the converter, so I used the converter from the bad, engine, and had ran fine until now. I just wanted to let everyone know what was going on, I will look into it a little more tomarow.

If it's super hot under the car, that sounds like clogged cats or muffler(s). Hot exhaust gases take longer to escape and everything gets hella hot.

KFelkner02

So would this possibly cause this trouble, I gutted the two Pre cats, and I think all of the main cat, I could not get it off, so I stuck some pipes in there and gutted it all out, I was told it would all just blow out, I was thinking of taking the exhaust off, right after the two precats, to see if it ran any better, I just wanted to make sure that it won't shoot any flames or anything.

I had also forgot to mention that after I tuned everything up, the buzzing/beeping stopped, it doesn't come on.

I put the car up on stands today, and took the back two wheels off, so that I could run the engine and put it into gear. Well, I put it into gear, and it would last forever, without a load, but as soon as you step your foot on the brake while in any gear, it would stall the engine, all though many times you can recover it by putting in neutral, I think, maybe the Torque conveter went bad again. Is there a reason why these keep going bad or is it just another coincedence?

I am being serious here... I have done this more than once. Make sure that your parking brake isn't on. If you have a stick, then you would stall. But seeing how you are mentioning a torque converter, I would think that you have an automatic. if its an auto, then you would think that it would just happily sit in drive...
