previous owner was in the process of replacing fuses and what worries me is that there is a cover to a fuse box in the interior but as I AM a huge noob i dont know where it goes

i know there is one box located near the battery but what about the other?

thanks BAttery check this weekend for sure

also the rapid clicking I have been hearing, could that be the starter or a failure on some kind of solenoid?

If your battery is anything below 12.0 volts when you are not starting it, the battery is dead. Replace your battery or get it FULLY charged (13 volts or 12.6 at least). The clicking you are hearing is caused by a lack of power coming from the battery.

The other fuse box is located infront of the drivers side door, below the dash in the left kickpanel. It contains mostly fuses that are only for the interior electronics or the lights. I think there is a fuel pump fuse in there tho... I don't quite remember.

omg ppl must be think round here cuz they haven't answered your question. I am a newb to rx-7's but have been through and through plenty of cars. If the starter is just clicking and the lights flicker then u have either A- dead battery or B- bad connection either at the starter or at the battery. Probably from tryin to turn it over so much. As for the fuel pump. When u turn the key to the one position u should here the fuel pump turn on. It will be a whirring noise in the trunk of your car. The on position is the one right before you crank the car over when all the instrument lights come one. I would put some oil in the plug holes though. My car did the same thing and flooded and that is what I had to do. Took a little time, but I got it running by having my friends push it and I pop Started it. Check the battery first and make sure that is good. Then clean the plugs and try the oil trick

UPDATE:
today i hooked up my vans battery to the 7's and then charged it, when I tried to start the 7 it feels so close, it sounds like im getting compression and i hear the pop pop pop but it doesn't startup, just turns over like that

everytime i kept the key turned the engine sounded like it was getting closer and closer but i would hold it for like 15-20 seconds without success.

was this a bad thing to do to my 7? trying to start it repeatedly without success ?

anyway I tried putting a small amount of ATF in the leading plug holes and that seemed to help but it sill wouldnt start up.

i didnt put alot of atf fluid in just a tiny squirt into each Leading chamber.

also Im getting smoke from the exhaust so i guess thats a good sign.

my only idea is that maybe I dont have spark in one of the 4 plugs.
i will check tomorrow.

any suggestions and help are welcomed.

4 hours away from you lol


i really don't know if i used enough atf fluid to try to get it cranking, I was going to use oil but i wasnt able to find something to contain it while i put it in the plug holes

so do i repeat my previous thing?: atf fluid and crank?

Where in VA are you located? There are quite a lot of folks on this board from there. If you post in the SouthEast forum and ask nicely, someone may be able to drop by and take a look over things for you.

Heck, I'll post if you are uncomfortable with it.

Good luck,

if i remember correctly the coil pack closest to your battery is going to be your trailing plugs and the one next to your firewall is going to be the leading plugs...leading being the top plugs....also if the lights start to dim while cranking then your battery is loosing to much juice...if you think it is flooded then take your plugs out and clean them up...put some oil in the trailing plug holes then replace the plugs...and then crank it over again and it should solve the problem...may take a couple of tries though
Both of these posts are wrong!

Leading plugs are the lower plugs.

Second, the fuel pump will NOT run in the ON position. It only runs while cranking, or if the AFM detects airflow, or if the check connector is jumpered. (at least for S4's.)

Also, I am not near my car right now, but isn't the leading coil near the battery, and the trailing near the firewall?


Dude, put a little MMO in there and try cranking it without the fuel pump running (Hold your foot flat to teh floor). This will not start the car. Do this for 10 to 15 seconds at least 3 times 10 minutes apart. Then, try to start your car normally.

If it doesn't start, check spark, and check fuel. Have you put any NEW fuel in the car? If not, put in about 5 gallons of 87 octane. And try the cranking 3 times without fuel again. Then try to start the car normally.

Let us know how that works out.

thank you so much for clearing things up although I do know that at least my trailing plugs come from the terminal near the battery and that my leading plug terminal is placed near the driver's side firewall

to clarify what is MMO?

I will try doing the 10 minutes apart thing

and I did realize this week, that I needed to add gas because its been sitting long enough...

does anyone know how long it would take some 87 octane to go" bad" if thats possible?

thanks guys

you need air, fuel, and spark. If you suspect its not getting fuel spray some throttle body cleaner into the intake and see if it will run for a second if it does youre not getting fuel. to check for spark disconnect the plug wires and suspend them close to a conductive metal and have someone crank the car while you check visually for spark. and make sure the throttle opens when you press the pedal, and make sure the iac isnt clogged. all these checks are very easy. Less than 5 minutes. if you have three check your plugs than do a compression check.

MMO is marvel mystery oil.

For the coils, what does the top of the coil say? (L1, L2, ooorrrr T1,T2 near the battery)

about 6 months is what I "think" the lifespan of fuel is before it starts to go bad.

DON"T PUT ANY FUEL SYSTEM CLEANER IN THE CAR!!! They are all "snake-oil". (Unless of course, you use the "professional" stuff that you can't get at the parts-store down the street.)

ok couple of questions

do i disconnect all the plug wires and remove the spark plugs from the wires and then do as you say and crank while someone holds next to a metal surface.?

and what is IAC?

ok so new fuel

and to answer a question: near the battery are the leading plug wires and whole setup
near firewall are the trailing.

thanks so much


also heres a wire that is disconnected, i dont know where it runs to...

Have you tried putting some fuel in the intake?
Good luck with the start up .... i feel your pain

nope

thanks though

and today I checked spark,
All the plugs have good spark but one of the lower plug wires is less powerful than the others,

so that leads to another question and I will search right after I ask this

will any old plug wires work for my s5?

thanks

Yes, but good luck finding a set that'll fit properly.

Dude, I'm in the exact same situation you are, except I have an S4 and I'm probably even more of a noob

I killed my battery today after trying to start it a few times, had to buy a charger and now I have to wait till tomorrow

Anyways good luck with your car!

OK, quick post to try and help.

The coil pack closest to your battery is the leading coil pack. Please ensure that the plug wires going from this coil pack go to the lower (leading) spark plugs. To make a long story short, your leadings are waste fired, so it does not matter which plug wire goes to which bottom spark plug. You will learn about this as you progress.

The coil pack closest to your firewall is the trailing coil pack. Please ensure that the plug wires going from this coil pack go to the top (trailing) spark plugs. In this case, ensure that the plug wire leaving the trailing coil, closest to the firewall goes on the top spark plug closest to the firewall, and the plug wire leaving the trailing coil, closest to the front of the car, does to the top spark plug closest to the front of the car.

Please verify this before trying to start the car. If you do not have the plug wires in this orientation, you most likely will never be able to start the car.
