I'll bet the first thing on everybodies mind right now is, "SEARCH YOU NEWB!" But I did, and didn't find the answer for my specific problem. Here goes..

It got really cold out, and I couldn't start my car for a few days. I come to start my car, and it..well, wouldn't. It would just do it's usual *rechurchruchruchur* like when it's flooded...except it sounded a whole lot slower. Like when you're battery is going dead. Well, I hook it up, start jumping it. Well, it sounds faster this time, but still won't start. Though when it's hooked up for jumpng, it will randomly BEGIN to start. but won't. Well, after about 15 minutes of waiting and trying, it kicks on. I push and hold the gas, let go for a second...it dies. Well, all the fuel I've thrown into the lines blew out my ***..smoke everywhere. Well, from them on I kept trying to start it, but the usual random almost starts kept kicking in. I would randomly get it to start, but even if I give it gas, it wouldn't stay on for more than a second or 2.

Well, today I just swopped out batteries from another car. I couldn't hook my battery up to his *Stupid Kias and their needing TINY batteries...* I couldn't fit his cables on my battery...OH WELL, I said. I hooked his up to mine after some trouble on THAT...It was up, I turned the key...it wouldn't even do it's almost turn overs..it would just keep chugging away. I would even turn off the fuel injection *from a kill switch I have installed* and flip it back on...nothing would change in the sound of it trying to start. I'm starting to get kind of frustrated. To me, it sounds like it could be a BILLION things. I mean, from something like an O2 sensor, to fuel lines, to fuel pump, it's just boggling. Anybody have any suggestions? And remember, I'm an idiot when it comes to cars..I can do some simple stuff...but if it gets too complicated, bring instructions please

Thanks in advance.

what exactly are you asking???

Sounds like you have a bad or dischargd battery and flooded engine. If you have the wrong weight oil in the engine, it will also lead to harder starts and flooding more often in cold weather.

CyberPitz

The cold weather has plenty gone away. We up to the mid to upper 40's now. If I did indeed have a bad or discharged battery, wouldn't that other battery, which starts up the Kia every time, have turned my car on then? I've tried taking off the fuel injection fuse, and trying to start it, to stop the whole...floodingness...but that still didn't help any.

And right now, if I try to start my car, my battery will just go in a slow manner..*Ruh.ruhruhruh...ruh.....ruh.......ruh...* like a dead battery. That's why I thought it was the battery, but since I put that other one in, and it didn't start the car...I just don't know.

I am having the same problem in my car here in washington state, I replaced my clutch and put everything back together and after sitting it just wont start, it almost wants to start but no quite enuf to do it, it started for a second but then died, it sounds as if I am having the same problem I have checked for spark and even cleaned my plugs still no start almost but not quite, i am totally pissed, o my car is an 1990 s5 gxl, sorry to kinda thread jack but your post saved me time of making my own,

carolinaTurboII

dudes, i'm having the same problem i think. mine is smoking from the engine bay too kinda by the turbo. but when i parked it, it was fine. mine also backfires too.

CyberPitz

Yeah, I checked m spart plugs, they are sparking. I was able to suck out gas from the fuel line with ease...not sure if that means much..

carolinaTurboII

how did you suck out the gas?

Icemark

what weight oil are you using?

and the Kia probably has much lower compression than a Rotary motor so I wouldn't consider that a test of anything. Is the Kia battery at least 330 CCA???

Not sure what the Blank that is supposed to mean.

Are the spark plugs wet?? If yes, then the motor is flooded... pretty cut and dry

It starts and dies randomly. I'm having this problem, I think it's either a bad temp sensor or a bad air flow meter. Also check your main ground next to the starter. I switched the ground from being bolted to the back of the starter to being bolted closer to the engine.

First things first, try to fill up the car with collant because if it's low it might not be getting fluid to the temp sensor and it's feeding the ECU bad readings.

You'll know if it's the AFM if it starts and revs to 4500 rpm and dies.

Back when I was having problems with my car, a very knowledgable form member I call the rx7 cleric PM'd this info to me:

I think you have a lot of basic rx-7 stuff to do. The 1st thing anyone should do when purchasing a rx7 is to check for vacuum leaks (take off the airflow meter cover it with a couple layers of plastic wrap, and reinstall it. Use the pressure sensor line to pressurize the intake tract (~5psi)). Listen for leaks under the manifold, and at any valve attached to the intake tract.

THEN the second thing to do is to check all ecu inputs/outputs at the ecu to make sure the values are within spec (there is a list in chapter 4 of the fact manual) and check the ecu input voltage using the ecu ground versus the ecu input voltage using the chassis as ground. If the voltage using the chassis ground is higher you should add ground to your engine and re-ground the ecu. If everything is ok, then start fine tuning the tps/variable resistor, etc...

THEN, wire the fuel injectors to their rails, remove the rails (just far enough to get the tips of the injectors out of the intake manifold). Turn the ignition on and jump the fuel pump connector (green, near the pressure sensor) and make sure the injectors don't leak.

THEN, since someone messed with your fuel pump circuit, make sure the hot start function (I think that's what it is called) is working, aka the fuel pump is getting 10V (or whatever it is suppose to get) under certain conditions and 12V under others (check the fact man).

On the plugs on average they should be changed every 3 to 5 k miles, my turbo will eat them in about 2k, the vert in about 3k.



Hope it helps

are your interior lights flickerign/dimming when this happens? sounds alot like what happened to me, had to reground one of the coils and problem was solved

CyberPitz,

How old is your battery? To me it sounds like you are out of juice. Charge it completely and have the parts store load test it. If that passes, check to make sure it is grounded well (same w/ starter).

As others have mentioned, pull out your plugs and see if they are wet. If so, you are flooded. If they are not, make sure your fuel pump is getting voltage when you turn on the ignition. You can listen to hear if it is pumping.

If that is working fine, check that the injectors are getting a signal from the ecm to pulse.

How low is your fuel (sorry, had to ask)? If it is really low on the gauge, you might just be out. The fuel gauge isn't 100% accurate either.

If all of this is fine I would explore looking for vacuum leaks, checking tps, and afm.

BTW the comment about oil viscosity is valid. I know tomorrow it will be around 50 for us (also from Joplin area here ) so if you are running 20w-50 it won't affect anything.

If you continue to have problems, just pm me and maybe I can help you out with it in person.

It might be because of his setup. He makes 300 hp on his turbo. It's insane, I've been inside it and with all the sensors and crap it looks like the back to the future car. Sounds like it too.
As for me, I got over 10k miles on my plugs till I had problems with running on just one rotor on cold mornings. That's why he told me to get new plugs, after that the problem went away.

CyberPitz

Well, update. I got my car towed to a shop, and they said something about a, bare with me here...a "Coil Booster"? I don't think I heard it right. My friends say it's an "Ignition Coil" that I'm needing, and they say that's over $1000. I really HOPE that isn't what I need, since I don't have that kind of money. Does this sound right to anybody?

*The won't start thread isn't what I was hoping for..it's a roomates thread that I didn't know he posted with...sry for this double post in 2 different threads :P*

I have spare coils, dont let them mess with your car

wait hold on, how did you check for spark and did you check all your plugs?

CyberPitz

Well, here is an update. Apparently, my car is running right now, for some reason. It's not running "well" they said. They put some new spark plugs in it, and it ran.

We tested new spark plugs that wal-mart said were good for my year car, and apparently...not....

Hmmmm..interesting.

RX7freak08

Uhhh I know you have gotten alot of people that are having the same problems and you are getting one more I'm am having the exact same thing you are having I have to put a battery charger on my battery and have it sit for about 1 hour and then go outside and make sure that the engine isn't flooded first before you I try to crank it then i try to crank it with the fuel switch on then it gets as high as rpms as it goes and switch it off if you leave it on it will flood the engine and the rpms will go back down but once you turn it off it will get higher and soon come on then once it is on make sure you flip it on more time and then it should be good to go but my problem is that I'm not having enough spark or enough power to start it with me having to use a battery charger each it won't work out the alternator is good the starter is good and the battery is good the spark plugs are good and the only thing that I can think of it that the battery isn't putting out enough power to crank the engine fast enough to get rid of the gas so it doesn't over flow or I'm missing something if you find anything please help me too. thanks

Out on a limb... Your fuel had water in it. It got trapped in the fuel filter and Froze. Not letting enough fuel to get by.......

CyberPitz,

I'm moving back to Joplin this week (bought a new house!). If you are still having problems, I'll help you out next weekend. As far as I know, Wal-Mart doesn't even sell rotary spark plugs (NGK BRQ-7's and 9's).

If you need a new coil, did they diagnose if it was the leading or trailing? I've got access to spares that are good if you need them. I think $40-$50 is closer to what used coils are going for, not $1000.

I had the same symptoms. Turned out to be a leaking pulsation damper bleeding off fuel pressure. Hope this helps. G
