RX7 Turnover, need help.
 

So me and my buds put on the starter tonight and to our amazing surprise, it cranked over. It start, probably due to old fluids or something, but we then checked the apex seals by takin out the spark plugs and startin it up, we heard pops, but we arent sure if theyre good, we just dont know. after a little bit, and draining the old gas and putting new in, we tried to turn it over again, but it didnt. wtf??? we think it might be wiring issues but we arent sure, any ideas?

It didn't warm up and you flooded it...

:cool:

-needs a strong battery so make sure its up to snuff & spinning her well
-pull plug wires, make sure all are sparking
-change fuel filter!!!!!!!!!!!!! - under car in front of driver rear wheel - $3 part at NAPA, Fram G12 I believe-

ohh, haha, well for some reason its not turning over now, what wuld cause that? cuz it did, then like 20 mins lata it didnt.


k, will do, think i culd get one at an autozone?


and how wuld u unflood it?

i also need to know how to bleed the clutch, air got in the tubes or whatever, bc there hasnt been any fluid in there for a lil bit and we just put some in.

How to un-flood a rotary: Pull the spark plugs, choke off, throttle open, turn engine over for 10 seconds, put plugs back in, try to start it, it floods again, realize you have carb issues, have a conniption ... don't you love first gens?

On the other hand, if the engine won't turn over, then flooding isn't your problem (yet). Crawl under and check that all the wires are getting good contact on your starter and solenoid. Does the solenoid click when you turn the key? If so, either the starter is bad or your engine is locked up--try tapping on the starter with a hammer, if it works you have a bad starter. Solenoid doesn't click, re-check your wiring. Let us know what you find.

Bleeding the clutch is a two-man process: First make sure your clutch resivoir is full, leave the cap off and the bottle handy. Find the bleed screw on your slave cylinder, it should be on top of your engine, toward the back. I do not have any pics handy, but follow the rubber line coming from underneath the resivoir. You will need to pull the air cleaner off, and possibly the fuel lines from the firewall so you can get access.
Now grab an 8mm wrench and break the bleed screw loose (carefull not to break it off, a little PB blaster helps on the rust) and tun it back just till you feel it close. Now get your buddy/girlfriend/little brother to sit in the driver's seat and pump the clutch pedal slowly.

Now just after the pedal starts going down, open the bleed screw about a quarter turn, and have your buddy call out justbefore the pedal hits the floor--you want to close the screw while the pedal is still going down--slower is better here. With the screw closed, have him lift the pedal back up, and repeat until good clean fluid comes out with no air bubbles. Remember to keep an eye on the resivoir, if it runs out, you'll just suck air and have to start over.

Good luck with the starter, and let us know what you come up with.

1. Clean up the connections at both ends of both battery cables.
2. Get a good charge on the battery.
3. Start her up.

If she is flooded, just dump an ounce or two of Seafoam down the carb and then try it again.
That usually gets them going again when nothing else will. Much easier than the traditional methods of deflooding. :)

thanks guys, ordered a new fuel filter and studs for the lugs and NGK plugs. maybe running this weekend or next?

i also have a guy in the county over wanting to come over and look at it, hes a mechanic that loves rotaries and wants to get this thing on the road, so i might have him help too.

When y'all were messing with the spark plugs, you probably disconnected or broke the wire feeding the starter solenoid if the loom has come undone in that area if by "not starting", you mean it won't physically crank over at all.

For unflooding, I tried the Seafoam spray, then the Seafoam liquid in a bottle and neither started the car for me when the '84 crapped out on me a month or so ago. I ended up using the following procedure which is C&P'd from New Member Tech...it got the job done, the mosquitos left the vicinity as an added bonus...:crackup:...Here's the thread from where the above comes from...you may recognize some more similarities.

Not starting...

:cool:

thanks for the help man. i wil tell u waht happens once i have the crew over again to work on it.

aite, so me and my friend were bleeding the clutch and we got the air out of the system, but when we retighten the bleeder valve, the clutch wont go down. wehn we loosen it a little, it goes down like its money, but the fluid comes out of the bleeder valve, wahts the problem?

Either the clutch slave piston has rusted internally and jammed (happens) or the throwout bearing is stuck/corroded in place (happens rarely).

and how wuld i check these and how wuld i fix them?

How to check spark?
 

aite, so me and my bud were tryin to start the rx7 tonight, and we know there is fuel, compression, just not sure bout the spark. we think the distributor caps mightve gotten water in them cuz it was sitting so long and culdve done something to the spark. how wuld we check the spark and distributor caps if there isnt any spark?

Pull the spark plugs out, lay on the fender, turn engine over.

ohh, ok, i will let u know the status then, waht if i get not spark?

Then search. I have answered this question at least 3 times in the past week.

aite man, i will let u know waht happens

All members need to download a copy of their year FSM if you are going to work on your own car or buy a Haynes or Chilton manual. All of these basic questions and trouble shooting information is contained in those manuals.

Copy and paste the link in my signature to get your year FSM.

...And your wiring diagram...

Need help on getting engine started.
 

aite buddies, we got a problem. We tested spark in rx7 today bc it was finally dry out today and not raining. We tested the top two and they produced spark, bottom two however don't. What might cause this, and would it prevent the engine from starting up because we weren't able to start it up. Help me out, i wanna get this thing running asap! thanks.

Did you swap out the ignitors to see if the trailing (bottom) would fire?

Don't you mean Leading (lower):) Engine will have a harder time starting if the lower (leading) plugs are not firing.

There must be a thousand threads on my car won't start?

We also have a thread about posting up when you need help that states to give us information regarding the issue.

You know, things like did you just get the car and it was never running. Or it was running and stopped running. Or I started the car and moved it a few feet then shut it off and now it wont start.


Sorry but this kind of stuff is getting very frustrating for those of us that have answered the question a thousand times.

In the meantime download a copy of your year FSM by copying and pasting the link in my signature. Then follow the trouble shooting guide for your symptoms.

aite, we found out that the leading ignition coil was shot, so we got a new one and still didnt give them spark. im thinkin that the distributor cap might be bad, but idk. im gonna have my one electrical engineer friend come over and check the wiring and maybe get a new dist. cap. we will see.

I doubt that there was anything wrong with your coil.

Are you going to tell us what year this is?
