1986 rx7 non turbo, I bought the car last wednesday, the car drove home just fine, after i got it there i cut it off, let it sit for about 3 hours and then wanted to show a friend how it ran, and yada yada. anyways it would not start. so i did what anyone would do, i checked fluids drained gas, put 5 gallons new, and changed the plugs. it started right up. it ran for about 1.5 hours total time, not its not starting again, i pulled the plugs and there black as night. any ideas.


I was thinking that it may be the ingition coil.

let me know im watching the post very closely for your response, and thank you again

 

wow cant type it is indeed an rx7...

 

isn't that excess oil...

 

no , its not wet , its dry , looks like carbon buildup

 

no no...My instructor just told me it probably is oil...
I go to a trade school

 

well what can i do about that, i have checked that the apex seals arent bad . according to this site and the sound clip the motor is fine.. http://www.aaroncake.net/rx-7/blown.htm

 

Have you looked in the Faq's?
Where are Guru's when you need them huh?

 

ive tried what it says in the faq, did that last night and again today, nothing.

 

maybe your rings?
I wish I could be more help bro

 

but dude it doesnt have pistons, lol ,im a rotarie noob , i just bought this a few days ago, before that i drove a camaro.


rings , assuming around the rotaries??? , sorry .

 

i bought mine about almost 3 months ago drove fine for about a month and a half now its just sitting there cant get it started.... i go to turn it over it almost catches and then just goes to normal cranking, car is getting spark and fuel put new plugs in (80 bux later) almost grabbed but didnt.... i know theres some sort of a leak somewhere cause while its cranking its making a hisssss sound.... ill drain the oil and try er again... but i pm'ed aaron cake he lives by me about 15-20 mins away hopefully he can come check er out. when i get it fixed ill let you know what was wrong so then you can try and do the same

 

thnx alot, can i ask what draining the oil does tho.. just wandering. my current oil is new and it is clean.

 

Sounds like its flooded...

Try pulling the fuse in the main fusebox under the hood called EGI INJ. Crank it for 5-10 seconds then put the fuse back in and try again.

Pulling the fuse will make sure that it doesnt try to inject more gas so you can burn off the excess.

These cars are very prone to flooding, they have a wierd issue with injectors sticking open when the car is turned off before the engine speed goes back to idle. Used to happen to me a lot but i got used to letting them idle for a few seconds before shutting it off and mine hasnt flooded for years, except when someone else drives it.

Hope this helps you out.

 

Ooh!

 

e tried de flooding it , could it be flooding if there was weak spark, not enought to ignite all teh fuel , or is that unlikely?

 

ok , well i jsut found out i wasnt getting any fire on one of my wires, its the wire thats bad , i pulled it off and got shocked, atleast i no its not the coil, would only 3 plugs firing cause all of them to be dark and no longer fire???

 

the plugs could look black because its just runnin a little rich or maybe there just old...it sounds like a flooding issue

 

ive been told its running rich the plugs i put in were brand new , withing an hour of running it wouldnt start and they were black. , i put new plugs in today it started up ran fine no shutters , then it stopped again , check plugs they wer black.

 

does it smoke really bad and if so what color is it?
