car doesnt fire???please help
 

ok i parked my car this was about 3 weeks ago,the next day it wouldnt fire..
it turns over and all cranks fine...ive checked the fuel injectors by taping them into the rails and try to turn the car over they squirt fuel fine..
my coils are firing(wire to strut bolt teqnik) and when i try to start it the tach bounces around a little..doesnt that mean your getting spark? ive replace the 02 sensor and fuel filter and pump also...could a bad ignitor be the problem? or maybe the main relay?

ps its not just flooded

iT'S FLOODED

Do this. Buy a can of starter fluid.

Disconnect the fuel pump connector.

Spray starter fluid for one to two seconds max into the air filter or the snorkel that leads to the snorkel.

Start the car. It will go varoom.

Reconnect the fuel pump plug.

Spray starter fluid into the snorkel for one to two seconds max.

Start the car. Varoom, varoom. putter, putter.

It was FLOODED

:withstupi

So Hailers...

If I'm reading this right, you're saying you can clear a flood without pulling the plugs, simply by using starter fluid? I like that method!

.....It's flooded. As the owner of a gen2, one of the first things you need to know is that if your car doesn't start, but it IS at least making an attempt, 9 times out of 10...it's flooded. Pretty much the only time starting problems are not caused by flooding is when you turn the key and hear, "click".

That being said, your best bet at clearing it up is all right here ---> http://rx7.com/techarticles_unfloodFC.html

P.S. Even if your problem isn't flooding... it's the first thing you should try passing the blame on.

lol guess noone can read english these days....its not freakin flooded...it doesnt attempt to start it turns over but doesnt fire wats so ever... the injectors are firing but the confusing part is no matter how much you try to start it,when you pull the leading plugs they are BONE DRY,but the trailing plugs are wet....when it use to flood the primarys would also be soaked... its liike the fuel isnt getting to the leading plugs...its been like this for a month now...and if it were flooded after 1 day it would have started....and ps i have a fuel cut switch and switching it from off to on doesnt make a shit of a difference...i have changed out the afm.ecu,coils,resistor pack,fuel filter etc etc

ps when it use to flood pre fuel cutoff switch...it would still make a combustion stroke(it would start to start then die) now it does nothing but rotate and rotate without a hint of spark even hitting fuel...ps i dont mean to be an ass but i know its not flooded ive delt with flooded 7's for a long time and this is not the case

Spray starter fluid in the filter for one or two seconds. Start the car. If it starts momentarily then its a fuel issue. If it does not start it's a spark issue.

If the rpm needle jumps it means the trail at least have spark. The lead spark is unknown.

If you have experience with stabbing cas, remove the cas but leave the connector on it. Spin the gear on the cas with the key to ON and ONE of the lead plug wires resting just out of the coil. If you have a large spark at the wire hanging out of the coil then your lead coil is good and most likely the wires also. You get a MUCH larger spark this way vs spinning the engine and looking at a sparkplug wire on a fender. You also don't wear out the starter .

You should also be able to hear the fuel injectors click as you spin the cas as described above.

thanks, the injectors do works they click and squirt fuel,i just dont get how the trailing plugs get soaked and the leading stay bone dry..just doesnt make any sense to me

I'd go to square one. Pull the fuel pump connector apart and leave it apart. Spray starter fluid into the air filter for one to two seconds. Start the engine. VAroom. Do it again. Varoom. Reinstall the fuel pump plug. Spray into the filter for one to two seconds. Start the car. Varoom, engine keeps running.

Your lucky. I'me gonna stop posting on this thread.

I usually just pull the leading plugs, clean em up, leave them out, and pull the EGI fuses, then crank the shit out of it until there's no more gas 'mist' coming out from under the hood, hasn't failed me yet on a flooded car.

did what you said sonicrat still no go ITS NOT FLOODED!!!???

Pull the plugs (and just to be sure, get some new ones), pull the egi fuse. Spin the motor with the starter with the plugs out. Listen to how it sounds. Should be some strong pulses coming out of the plug holes, if they sound weak or 'soft', the seals may not be sealing enough to create compression. It could be the old 'car sat for awhile and won't start' story.

The goofy part is, if this is the case, it also leads to a flooding situation. Unflooding it doesn't help, but all that gas will foul the plugs.

yea ive done this make good compression,but no fuel reaches the leading plugs,only the trailing wich doesnt make sense?

How many times have you had the trailing plugs out?

The reason I ask is that (if I recall correctly) the leading plug holes go all the way thru to the inside of the housing and the trailing plug holes are actually pretty much blocked off with just a small hole opening into the housing. Any chance the fuel has made it thru that hole and filled the area around the plug?

I'm guessing here....that's the only reason I can think of that the trailing would be wet and the leading dry. But even this doesn't ake alot of sense. Also, if the trailing plug is not totally dry, that little hole will prevent it from drying out from pumping air around by cranking.

just twice ive check the trailing just to see if they were wet since the primarys were dry...doesnt make sense to me either ive checked everything?? boggles my mind

I'm at a loss.

All I can say is to follow Hailers starting fluid process (with fresh, new plugs). Eliminate fuel as an possibility. There is a chance that for some reason, what you are seeing is normal. The trailing plugs do not fire all the time like the leading, so fuel may get in there and make them wet while the leading are dry. Especially if the trailing coil is not working right.

okay sprayed starter fluid in there ,and still never even made an attempt to fire...so its got to be some sort of ignition prob,yet when i check for spark its fine?

If it's ignition, but you have spark, then it would point towards timing. But, two really big buts, 1- if you haven't messed with your timing, then there is no reason to mess with it now (it hasn't moved) which would lead us to ...2- an electrical/electronic issue (coils, grounds, cas signal, ?)
Spark plug wires are on the correct coils and plugs, right?

When you sprayed the fluid in, did you use brand new plugs, unplug the fuel pump/egi fuse, and clear the rotor chambers good first?

I'm afraid I have go for the weekend, now.

Good luck.

Just remember, there is no problem with going back to a square one, a complete fresh start. Advancing to 'the next level' can lead to danger (time and money wasted) if you miss something in the 'obvious things to check'.

Yea, im guessing you either have poor compression, or your timing is way off. It is possible to have timing off so much that it will not start.
You can check the timing by having a friend turn the engine over in the drivers seat, while you sit there with a timing gun turning the cas until its right. Try not to keep it going so long either, you'll overload the coils, do it for like 10 second bursts max until you get it right.

k will try soon..

still dont start? any more ideas?
