13B keeps flooding(tried deflood diy)

I got a 1985 gslse. It has the 13b 4 port in it. Problem is I got it to fire up for a brief pop after i did the deflooding procedure but immediately afterwards, the engine proceeded to flood itself. I have checked for spark by placing a nail in each plug wire one by one and cranking the engine. All plugs arc to the chassis when cranking, so I assume there is spark. Def has fuel as it keeps flooding obviously. Ghetto compression test by listening for the pulses, consistent even sounding. So what the heck could be wrong. Dizzy is lined up correctly set it according tot he manual, lining up the markings and setting the motor to tdc.
Here was my deflooding procedure in case anyone is wondering...
1 - pull plugs and disconnect fuel pump plug
2 - Crank engine with accelerator at WOT for about 10 seconds then stop, do this 3 times
3 - pour ATF into trailing plug holes and hand rotate engine 3 times, repeat
4 - reinstall plugs
5 - crank engine without pressing accelrator
6 - FLOODED AGAIN!!!!!

So step 5 is where i got a little pop from the engine and a load of smoke from the ATF burning, the motor then proceeded to drown itself in its own juice....

I am officially stumped. First time working on a rotary, rebuilt several piston motors including a v6 camry, i4 lancer, toyota corolla, honda civic... so mechanically I am pretty well off. But beign that this is the RX7CLUB i feel like you guys are the authority on this beauty so I humbly ask for the forums help... I have been reading but i just couldnt figure out the problem. thanks everyone

i know you said you saw spark, but have you tried new plugs? also, how old or what condition are the cap and rotor?

by the way, it's not relevant to your situation, but just so you know, unless you (or some previous owner) changed the engine, it's a 6-port 13B.

How do i check for leaky injectors? The intake mani has only four ports so the engine must have beenchanged

^oops. Was thinking about the whole 4 port 6 port deal and i remembered the ports refer t the number of ports on the lower intake mani and not the upper. lol ...diabolical1 you were spot on!

Yopu probably started it, moved it a little in the driveway, then shut if off. Flood city! I got my brighter's GSL-SE running again by push starting it with another car. The deflood procedure didn't work. ATF is garbage and will damage cats. Use oil if anything, but nothing worked for me. So a little push from another car and viola! Smoke city! But it was running.

if it was mine, i would disconnect the fuel pump, and crank it until it starts. eventually with no fuel, it will start and run for 10~30 seconds, THEN you can hook the fuel pump back up and see where you're at

Ahloha.................. first off GSL SE's came with 13b 3mm 6 port 2 injector engine (304) so if you have a four port it was either a old 13b (74-77)with carb or a turbo block , the next time you want to start the flooded engine just pinch off the fuel line with a vice grip and turn it over untill it starts runs and dies then start as normal, you might have either a low compression engine or a plugged cat or a loose fuel pressure dampener . screw (under white plastic at front of primary inj rail ) or a burnt resister in the engine computer ,open up computer and remove cover then remove the first board flip back and look for a blue resister that has turned brown, if it has replace the resister and your flooding days are gone(battery placed in car backwards caused burnt resister)good luck .......see you on the beach

Gonna try work on the car again today. Will install a fuel pump toggle switch to cut fuel during startup. Can someone take a pic of there ignitors showing the wire colors. Seems like someone messed with mines so i wanna check if everything is right...

remember just leave the pump off until it starts. if it magically started right now, there is enough fuel in there without the pump for it to run for way longer than you'd think, almost a minute.

IN easiest deflood procedure ever

To Deflood An gsl-se just pull the engine fuse under the drivers side part of the dash.it is the third one on the left(i think) anyway read the diagram on your fuse box cover

step 1= pull engine fuse

step 2= crank car for about 10 seconds(you may need a jumpstart box or battery charger if you have a weak battery

step 3=put fuse back in

step 4=start car

This is a little trick that i adapted from the 2nd gen guys to work on fuel injected first gens

AND IT DOES WORK!!!!!!!!!!!!

I bet the rookie has a 6 port egi engine.

Post engine pics for confirmation!

Simple bandaid, run a fuel cut off switch. As a rookie, I tried forever to chase down the flooding issue with a gslse I had a few years back, just installed the switch and never looked back.

flooding is very common on gsl se's,i had the same issue on a daily basis.i usually unplug my fuel pump n crank til it starts then dies,then plug it right back in.i believe u can install a fuel bleed off made for fc's & it should solve ur problem.good luck!

ive had to crank flooded cars for up to an hour at a time sometimes, the rx8's are the worst.

plan B is a pull/push start

+1 on the push/pull start. get someone to tow you. put the ignition in the on position, leave it in 2nd gear, tell tow vehicle to pull and wait till it starts. you dont have to go very fast, just make sure you have some kind of signal for the tow vehicle to stop. this works for me every time. good luck.

No,.................... but when it starts it might cause a fire if its full of fuel,and take you to an unhappy place,while you watch your car burn to the ground.Put the exhaust back on then pull start the old girl like the guys have suggested one more thing test your compression by using a normal compression tester ( with the lower air valve removed) remove either both top plugs or both bottom ones disconnect the power wires from the coils (no spark) then test each rotor,by turning over the engine several times and watching the gauge you should see three pulses each pulse is an indicator of the compression from each rotor face, test the other rotor as well. Any readings that are 60lb or less makes for hard starting,and low horse power ,also if the readings are low try my favorite rotary juice for removing carbon ,mix 50/ 50 Varsol/Atf or you can use Sea Foam too (note ) spray into spark plug holes,turn over and let sit (up to 3 days if necessary)I have used it to start Engines that have been sitting for as long as 10 years.......P>S> you also may have a stuck injector, check and compare front and rear plug colour tan is ok black is too rich, ps use new plugs, I had a customer try for 2 weeks to start his new engine,drove him nuts he triple checked every thing, then called me I suggested new plugs , he installed them after much resistance ,low and behold his car started right up,when using The Juice, when she starts be prepared to smoke out your area for 20 minutes or more ...... .........................................FP
