welp for one sounds like its flooded, pop the plugs out dry them then try it again. I had that same problem 3 years ago after taking it out of storage. I really dont know how it started but after awhile it caught and started. Try starting it without the clutch in.

Sounds like it's flooded. Do the de-flooding routine. (You must be new to these rotary things, eh?) If you don't know what that is there are a gizillion threads that deal with the various techniques so do a search and read, read, read. There are several increasingly-complex levels to the routine depending on how badly it's flooded.

Try the simple approach first: If you have an S5 (89-91), hold the accel. pedal to the floor and crank the engine over and it may start. (Careful to not burn out the starter motor by running it too long and not allowing it to cool down.) If you have an S4 (86-88) pull the EGI fuse and do the same thing until the engine runs briefly and quits, then replace the fuse and start 'er up. If it starts, you will get gobs of smoke that will eventually clear as the engine warms up.

The other possibility is that you have lost compression due to an internal engine mechanical failure in which case any de-flooding technique will likely not get it started.

Dude, It sounds like like either you have bad spark plugs, or a bad/Blown Apex seal.. lets just hope it's bad plugs. you can hear it fire, but it doesn't sound like it has combustion on all sides of the rotors. try doing a compression test on the motor. Bummer, hope it gets fixed!

Huh? It won't even attempt to turn over if the clutch isn't in. Search around for the unflooding procedure. I think its in the FAQ, but I can't remember for sure. Also try a compression check.

jgrts20

oops I have a S4. I dont use the clutch to start it due to the cold weather thingy.........brain cramp ;(

Again, Huh? To my knowledge, every manual transmission car ever made (at least in the past half century) doesn't allow you to start the car unless the clutch is all the way in. They do that so you can't accedentally start the car with it in gear. The cold start thingy is disengaged if its started in nuetral, I think.

dang. its flooded. take out the bottom two spark plugs and get a half cup of automatic transmission fluid in each hole, put the plugs back in. and i promise you it will fire right up, smoke like hell for about a minute, but it will run. what it does is soak up the extra gas and builds compression at the same time. i have done it everytime my car has flooded and it works like a charm everytime

I would try doing it just with removing the egi fuse first, then replace the plugs. ATF can theoretically cause a chunk of carbon to break off and pop a seal. A remote chance, yes, but a chance nonetheless.

matts86fc3s

best way to do it: get a clear piece of tubing, about 2 feet long, stick it down in the bottle of ATF and suck on it till you get ATF halfway up the tube then immediatly when you take your mouth off use your thumb or finger and put over the top end of the hole of the tube (that you were sucking on) and hold it and pull it out. notice that the ATF stays in the tube. keep holding. while still holding use your other hand to guide the other end of the tube as far as it will go into the spark plug hole and release your top hand and let the fluid flow down into the spark plug hole and immediatly put the plug back in. repeat for next plug hole. thne put all back togheter and crank. voulaa

Car has been sitting. Maybe stuck seal? Dumb some 10W40 in the spark plug holes and turn over by hand. (tablespoon in each rotor housing)

My dad's truck on the otherhand has a clutch safety bypass... put it in neutral, hit the button, and you don't have to use the clutch...

And most of the time a car converted from AT to MT won't have the clutch safety either.


You're car sounds like it's SOOOO close to firing up... I'd try a compression test to make sure it's got compression on EVERY rotor face...

Also, make sure your plugs aren't fouled.

Using a little starting fluid probably wouldn't hurt much either.

The first time I got my car to crank, I think I actually cranked it *longer* than you did in the first video...lol

Either way, sounds like you've got gas, and spark, so check compression...


I'd also try taking out the plugs and then turning it over with the spark and fuel disabled to get any nasty liquids out... Put paper towels on the outside of the holes to prevent making a mess in your engine bay though.

Your tach should bounce as you try and start it. Looks like a spark issue to me. Could be fouled plugs, swap out the leading plugs and see what happens.

Sideways7, not every car in the last 50 years had a clutch safety switch. 1st gen rx7s do not have such a device, for example.

speed_monkey

I can start my 86 base without pressing in the clutch... my 88 gxl in gatesville wont though.

Yeah it sounds so close!

LookThatsMe

well sure sounds like you got compression, removed the plugs, pull the egi fuse, take a paper towel and cover the holes where you removed the plugs and hold it there, get someone to crank the car, so gas wont spill out... if that dont work, repeat, but pull the egi fuse put a drop or 2 of ATF (automatic trans fluid) in each spark plug hole, crank for about 10 sec, let it rest for a min (dont wanna overheat the starter) and put the egi fuse in and try again... and making sure the EGI fuse is under the hood by drivers side strut tower

LookThatsMe

if that dont work worse come to worse is a compression test... if you dont have a compression tester take out the upper spark plugs and put your hand there get someone to crank and try to feel out if u have even air pushing out (3 air pulses)

I've never had a flooded 7, so I don't know what that is like. But your voltmeter is reading 10V before you crank? Is that right? If so, then trying to start your car like that with a low voltage is going to destroy your starter, if it hasn't allready.
P=V*A Assume your starter requires a certain wattage to crank over, if your voltage is low, your amperage will be high. Your starter can't handle high amperage. You'll burn it out.
If you have a bad battery(low CCA capacity), with low voltage, you won't be able to turn it over quick enough. It sounds like it is not turning over nearly fast enough.

That could be ONE of the problems your having.

try this, it may sound stupid but try it.
in the inside cabin fuse box theres a 15 amp fuse that is third from the bottom, second from the door. is it blown? if not you may have the wrong one check the next one over (theres 2 15 amps side by side)
i dont know what it does but ive started 3 7's after replacing it that wouldnt even push start. sounds like your prob. just check it.

That sounded like when I tried to start my parts car. Someone had sugared the gas tank before I bought it so I had never seen it run until I changed the fuel tank, filter + pump.

Anyways, I tried using a used battery but it didn't have enough juice to start until I jump started it with my van.. VROOM! Prolly needed some extra juice to overcome the electrical resistance you get from a well-used 20yr old car. Besides, RX7's aren't known for their electrical systems...well, not in a good way. ~rich

it does bounce, its just too dark to see it really

Here's something to check. This happened to me on my S5 and I've never heard anyone else comment on it happening to them.
I removed my stock air box and replaced the air filter with a K&N. Built a box and fabricated a mount for the Mass Air Flow Meter. The car would crank and crank before it would finally start first thing in the morning. By noon when I went to lunch it started fine. Next morning same thing. I thought it wasn't turning over fast enough so I bought a new battery. Nothing, same problem. One morning tried to start it, and it wouldn't start this time. I'm thinking leaking injectors and it was flooding. I thought I would pull the air filter and spray some starting fluid in the intake to see if it would start. When I went to push in the cone (S5 type) on the MAF to spray the fluid, the cone was sticking shut and would take a small amount of pressure to break it free. When I unbolted my fabricated mounting there was no more resistance on the cone. I guess my mount was twisting the body of the MAF enough to cause the sticking. Long story short, take a minute to see if the cone in the MAF moves in freely with no resistance anywhere in its travel in or out. The S4's have a different MAF than the S5's but the same problem could possibly happen with the flapper type too I would think.

first off you have an s5 so there is no need to pull the fuse, all you have to do is press the gas pedal all the way to the floor and this will cut your fuel. But what you want to do before this however is get some new sparkplugs because yours are probably fouled.

ITS_A_RX_THING

not tryin to be a smartass but why would you try to start it without the clutch in to help flooding

DREYKO

did you ever check that 15 amp fuse? inside the car?

Type_zero

yeah, i got it started today, but its smoking like a sonofabitch, i need to go to autozone tomorrow and see about getting new exhaust gaskets for the manifold and the missing cat
