i will be as short but detailed as possible.

i have an 86 gxl. bought the car last year, but never drove it.. it did always start though.. when it started, it would go to a high idle and then settle down after it warmed up. well, my brother was supposed to be fixing it, but now the car wont even start.. i have no clue what he did, but i know he went backwards. at least it started before.. he bought new plugs and wires for it and said it ran fine last time he tried it.. now it just turns oover and over and over, but no start. i can totally smell the fuel and you can see it coming from the tailpipes. i think its probably flooded, but you guys are the pros here.. this is my first rx7 so i dont know much. i dont know if he put all the plugs back in the correct spots either.. at this point, i dont trust whatever he did, lol. can you guys help me out and tell me what wires go to what plugs? i know the leading plugs are on the bottom, but i dont know which plugs are 1's & 2's.. thanks in advance for any help.

It sounds flooded. What you want to do is pull the EGI fuse, which is located underhood on the driver side. Its a little black box. The EGI fuse is the one furthest to the left. You will pull that and crank your car for about 10-15 seconds with the gas petal floored. Try and put the fuse back in and try to start it. If it still wont start, try this a few more times, and double check that plugs are in the right order, you can find that in the FAQ section, or do a search. Sometimes these cars get REALLY flooded, so you might have to do the unflooding procedure a few times. Best of luck and keep us posted.

1's or white dots are front and 2's or no white dots are rear.

I'm with nopistons if you're plugs are firing.

You can verify if ur plugs are firing by just pulling one the cables offa the plug and looking at the end while cranking. Just don't electrocute yourself.

thanks bro... any ideas on the high idle problem??? im gonna have to tackle that next.. maybe a sensor or something?

dude wait... you said when yo ustarted it up it went to high idle and settled down when warmed up and your brother was supposed to be fixing that. rx7s are supposed to idle up high when they are started. its the accelerated warm up process. should run at 3,000 rpms for like a minute then gradually settle down to about 750-850 rpm. if he was trying to fix that then he broke it. lol. and if its flooded just disconnect the fuel pump, take the wires completely off the car so you get no spark anywhere from them laying under the hood, pull the plugs out, leave them out and crank the car over and blow all that gas and oil out the plug holes, do this a few times, then spray your plugs with carb cleaner or brake cleaner, let them dry for a minute then put everytying back on (plugs, wires) and connect fuel pump. and put the car in 1st gear and hold the clutch down and start it, right when it fires up "pop" the clutch and drive away. it will run like *** for about 10 seconds but youll burn all that old stuff out and drive it around the block a little then your done.

your thermowax valve controlls the high idle at cold startup. you can get rid of it with no problems by doing the throttle body modification, wich i have done, works great, gets better response and no warm up/high idle bullshit anymore. if you live somewehre where it gets very cold then do not do this, your car will run like crap. leave it alone and deal with it, but down here in the south where i live it doesnt get very cold so im fine

ronnie22

k, thanks a ton guys.... i cant get into the faqs though.... so any help on the plug arrangement would be great. thanks again.

Ronin Rotary

No, the thermo wax only controls cold engine idle. It boosts idle only to 1200 RPM and then slowly drops to the normal 650 RPM as the engine warms. Removing it, will require you to hold the throttle when starting and the engine is cold to keep the engine from stalling.

It has nothing to do with High idle when starting. The BAC and AWS solenoids feed air into the engine for the high idle when starting cold. They are what is responsible for the 3000 RPM start up.

nopistons13

make sure you ground the plug before you crank it. lol. been there, done that.

ronnie22

ok, so i did the unflooding.. cleaned off the plugs, etc. still just turning over... so i did this..

i dont know if these engines are anything like regular engine, but i trioed anyways. i took a plug and , one by one, hooked it to each wire and turned the car over to see if the plug was sparking... when i had the plug hooked to either of the leading coils, it would spark.. when it was hooked to either of the trailing coils, it would not. on a normal car the problem would be obvious, but i dont know if there is supposed to be spark from the trailing coils when tested like this.. like i said, i dont know anything about these cars... do you think that my igniter for the trailing coils is bad?? does the fact that they didnt spark mean anything?? thanks guys.

Icemark

Doesn't matter... if the trailing coil is not even hooked up the car will still start if there are not any other problems.

ronnie22

k, gotcha.. just didnt know if the fact that it wasnt sparking was allowing it to flood out basically immediately.. on to the next thing i guess. lol

ronnie22

anyone have any other suggestions on why this bad boy wont start??? should i just try brand new plugs??? the fuel dlievery is DEFINITELY not the problem.. its spark..

Icemark

If you are getting spark on the leading wires, then it is not spark...


Pretty simple there.

What is the compression on the engine?

I am not convinced you have cleared the flood. How are you starting??? You should not be touching the gas at all (unless it is flooded and then you hold the gas all the way down without pumping, while cranking).

ronnie22

well, i always start it by just turning it over... i never pump the gas, but like i said, my bro is the evil-doer here. lol. on the same note though, i havent held it down to try starting it. figured it would just hurt the cause, but im gonna try it now.

Icemark

now you do have the front coil hooked up to the lower spark plugs (leading) not to the upper spark plugs (trailing).

Right???

ronnie22

yes sir. and the 1's to the plugs nearest the front of the car.

Icemark

On the leading coil and wires it does not matter, You could swap the leading coil spark plug wires on each leading spark plug and it will work just fine.

Only the trailing coil must be hooked up with the front coil (of the trailing pack) on the front rotor, and the rear coil (of the trailing pack) must be on the rear rotor.

ronnie22

ya, thats how i got it

dirtdox

You may want to hook up a battery charger. These cars seem to like full voltage especially when they have been flooded.

ronnie22

got it runnin guys.. thanks a ton! really. just did the unflooding process a few times and tried starting it with it floored.. was starting, but dying soon after.. abd sounded like $hit too.. put new plugs in even though the ones in it were brand new and vroom! all good... ima leave the high adle alone this time, lol.

SuperRotorMan

no idea

Badly flooding an engine will mess up even good plugs.
