1985 RX-7 GSL-SE Fuel coming out of the exhaust
#26
I've been reading and listening to the advice given before I chipped in my two cents worth of advice. I agree with Longduck on this one 100%. My car had a similiar flooding issue, everything was absolutely soaked.
It's likely time to have the fuel injectors cleaned and balanced. I would reccomend a company by the name of RC Engineering. http://www.rceng.com/
They took my two fuel injectors from my GSL SE and found that one was cracked and constantly leaking fuel and required complete replacement. They also had an irregular spray pattern due to years of build up and decay. They were flowing much worse then factory too - Something like 440CC's if I remember correctly, damn near starving the GSL SE of fuel. The stock injectors are 700CC's if I remember correctly.
At the same time, I would grab the part fiche from the FAQ Section and go ahead and order new O-rings for the injectors, top and bottom - as well as the bigger grommets for the top and bottom. Replace them at the same time you replace the injectors - otherwise you'll end up like me.. squeaky clean injectors and rotted o-rings that created a fuel leak and vacuum leak.
Might also be a good time to replace the Air bleeds inside of the engine also, if you have the intake off. I replaced mine at the same time I replaced the O-rings on everything and found that they were ancient, cracking and the o-rings on the air bleeds were letting air by them.
Lastly, it gives you a chance to inspect the fuel injector connectors. It's possible you have a fuel injector that has a bad ground - keeping one wide open and not closing. It'll give you a chance to clean the contacts and trace back grounds etc, to make sure things electrically are shiny.
Really, this comes down to generally maintenance and repair on a car that's older then I am. If you look after her, she'll look after you mate!
I'll post tomorrow afternoon all the part numbers I ordered from Mazda. You can get everywhere from them, cept for one that I had to get from mazdatrix.

I had the engine fuse still in and when I looked back at the video the fuel was coming out of the front housing not the rear while trying to start the motor
with the fuse out no fuel
Latest News: I used a brand new compression tester and still no compression
I even tried to reproduce the first video in my thread and still no compression at all
(the gauge needle doesn't bounce or increase)
This clip is no plugs focused on the front housing

REPLACE YOUR FUEL INJECTORS.
There, I said it.
The only time you get THAT much fuel in the system is when a fuel injector sticks open and is spraying at 100% duty cycle, all the time, including when you're trying to start it. These fuel injectors (there are only 2) are now 25+ years old, and they don't last forever. I'll bet you'll find that at least one of them, maybe both, will test as broken. Good luck,

You may have it so flooded that it will not produce compression.
At this point you need to disable the fuel and spark then tow the vehicle in 2nd or 3rd gear for a few miles and see if the compression comes up. I have had this happen before where my Se was so flooded that it would not produce any compression. After the towing it came right back up.
After you do this perform your compression test again.
