Hi everyone,
My car will start but the rotars wont kick and start to turn on their won without the ignition. I have done all the minor checks and checked the fuel pump and line, I think there isnt alot of air coming into my air intake, i think it is ment to suck ur hand if u stick it to the intake, but im getting nothing??? I have also used that starter spray that u pray into the intake and that did nothing either, the sparks are firing and the ignition coils are working, i just dont know what else it could be. Could it have anything to do with my crank angle sensor? Anyway any suggestion are welcome and if possible when suggesting a change of something or giving me advice on how to change something please try include a pic with what it looks like lol, because i dont know that much about rotarys. Thank you for you help

 

Your car will start but the rotors will not turn? In order for the engine to run, the rotors must be making their orbit...

Can you describe exactly the problem you are having? Does the car start? Does it only fire while you are cranking?

 

Its really hard to describe, but ill try my best. The ignition will start and everything will start turning, i can hear the compression if i listen closely and the spark plugs are firing but i dont thing they are firing strong enough, as in every now and than the motor might hit a spark and the rotor will kick and than it just goes back to what it does when you are starting the car. Its just like when ur starting the car but it never kicks in. When it first did this what happened was i started the car and it was running really irraticly and i could here what sounded like my airfilter valve opening and shutting fast, this was causing a relay under my front concole in the drivers side to switch on and off really fast, after that i never heard the sound again. But the more weird thing is that when i bought the car there where these two red LEDs connected to a green adaptor near the ignition coils for the bottom spark plugs, these lights turned on when the car stopped working, they have never come on before. I have a pic of them but the site wont load it?? I can send it to someones email if they think they can load it.

 

I believe he was having a hard time explaining that while cranking the engine turns over, once he lets off the key it stops, at least I think that is what he means.

 

maybe flooded ?

 

Already thought of that one, i have had about 3 poeple look at it, but the thing is none of them knew alot about rx7, one of the guys worked for holden. It isnt flooded its something else but i just dont know what it is? You guys are awsome, i didnt think i would get this much responce. Anyway i gtg to bed now, keep the suggestions coming because this helps me so much. Ill drop online tomorow. Thanx everyone!

 

I just saw the last reply, I have check the fuel and the spark, they are fine, but my air intake isnt really sucking much in, when i put my hand to it i can feel almost nothing at all? What would cause this? Remember this is only when starting the car in ignition, not when it is running.

 

Could be but i took it for a spin before that and it was running quite well, how do i adjust the timing? Or where abouts do i adjust it from?

 

Random guesses don't do anyone any good. Timing just doesn't suddenly change. If you know what the problem is, then good. Post the answer. If you don't, then don't post. Simple as that.

Start with the simple first. Odds are it's flooded, based on your description. Pull all 4 plugs, remove the EGI fuse, and crank the engine over several times with your foot to the floor. You will be amazed at howm much fuel comes out the engine. Now squirt some oil (about an ounce) into each rotor (use the lower holes, they are the most open inside the engine) and put the plugs back. Try to start the car.

If that doesn't work, then push it with another car. The push start will ALWAYS start a flooded car.

If it STILL doesn't start, then begin your troubleshooting. Use a proper spark tester to check for ignition at each leading (lower) plug. It will be easy to tell if you have fuel since during the unflooding, there should have been a mist of it coming from the engine.

If you have fuel, spark and compression, then the engine will start. Hell, it will start with only fuel and spark.

 

Forgive me for trying to have a sense of humor. I guess thats not included as part of communication in canada eh?

 

This poster is already confused enough...You whoring in his thread does not help the situation.

If you don't know, don't post.

 

Another good idea is that if you think that your spark is weaker than it should be, replace the plugs and wires. make sure you get NGKs (or another good brand) that have both Leading (L) and Trailing (T) plugs.. When I was starting up my rebuild, my engine would act much like you said yours was... It would crank (spin), but only turn over (start) if you did a complete de-flood to it and put a bit of oil in. My plugs were rather old, and I knew I needed to replace them, but I was using the "eh, i'll just get new plugs tomorrow" mentality. As soon as I put the new plugs in, it turned over every time I turned the key..

I'd look into that, If you haven't..

Good luck!

 

BTW: the LED's are used for testing the TPS setting.
They are normally removed for daily driving.

I suspect it has been flooded also.
Aaron's post above should work..

 

 

speaking of whoring....

 

If you look up near the top I did try to help contribute to this thread. Is your comment meant to deflect the criticism of you? How soon you forget the props I gave you on the Tii lip find…..

 

I know man. But i'm always the one getting called a ***** lol. Besides this is a forum there should be more than just question/answer communication. How the hell else do we get anything else done but answer all the same questions.


I didn't tell him to de-flood because it said it wasn't flooded so I though he would have already trying to unflood it.

hey bud, I love sitting in the hot seat myself. you should take pride in knowing that your no where near the worst (keep in mind I know I am on the list as well) that desert guy on the supercharger thread must have racked up 5 pages of the 20 just asking for the writeup. We should probebly chat in the lounge further.

Cortez, Follow Aarons advise, also, one of the most knowledgeable guys on the board is down under, NZ Convertable.

I know the NZ Rugby favorite saying is something like "our two favorate Rugby teams are New Zealand and anyone that plays Australia", however, I think rotary guys bypass that!

 

Thanks heaps guys, this site rules, besides the fact u guys argue more than post info LOL. What does TPS stand for?? the LEDs only turn on for about 10sec? If it is flooded what do i do than?

there are a few great threads on "flooding" do a search for them.

yes, we like to bicker - maybe a way to pass time in a boring job for me.
