Background: Duffman and I did some work on the car, we replaced the clutch line, brake booster, and fuel filter which later led to the replacement of the lines leading to the filter itself.
The fuel filter was bought off of Mazdatrix and is listed under the '79 Rx7 recommended filter.
Upon replacing the fuel filter the fuel lines wouldn't budge leading to the lines having to be replaced, so we bought some 5/16 inch fuel lines bought at Autozone.
Upon start up the car turned on but wanted to die, was able to start it 3 times but after that nothing. The fuel filter has fuel in it, the pump is working (tik tik tik noise coming from it) and there is fuel being delivered to the carb.
We charged the battery, and we let it sit over night to let any small amount of gas in the engine evaporate. We think it's flooded slightly, but not sure.
I have looked up de-flooding procedures and was only able to turn up this (link below) everything else was de-flooding procedures not working. Can someone give me a step by step instructions on how to de-flood a '79 Rx7 original 12a engine and carb.

I did start it up, and moved it into the garage yeah I screwed up pretty bad and then there was rain on top of that. Please help, I have a week to get it running or I'm dead meat.

 

The best way I've found is to clean the plugs and then pull the car or find a big hill and pop the clutch in second gear. A full battery at best will only get 250 RPM while popping the clutch will get 2500 RPM and thus better compression. Works every time for me on flooded cars. I have a tractor so I have my wife pull my car with it in our culd-de-sac.

 

Yeah, in Texas we don't have any large hills readily available. I also don't have anything as low as the Mazda even our Corollas will roll right over it if I gave it any gas. :/
Are the fuel lines the right size?
I checked them with the original ones, but the old ones are so stretched out it would be impossible to tell the original fitting.
What do you do if you have air in the lines?

 

Ignore most of my PM - I sent it before reading this.
You may be able to just pull the fuel pump fuse and spin it over a bunch. A freshly charged battery with charger attached, or jumper cables to a running car helps a lot. A couple ounces of ATF might do the trick - you will get a lovely cloud of sweet-smelling smoke that just sort of hangs around, too:



Failing that, pull the plugs, clean and dry them, and spin the moor over to clear the chambers (pull the coil wires first! Fire BAD!)

 

How would I properly spin the motor over?
I'm thinking I would have to use a screw driver or something along that nature, am I correct?
And where is the fuel pump fuse?

 

Also before I start a de-flooding procedure, I would like to see if I have any air in the lines at all.
I looked around on Google but nothing for rotary carb. engine on this subject, can anyone help on this too?

 

Just use the key to turn it over a few times, with all the plugs out it'll blow out and fuel that may be in there. If you have a gas stove, turn it on high and burn any fuel that might be on the plugs off. A lighter will work too. You could try the ATF trick too but I'd push it out of the garage first. If it still won't start we can try push starting it.

 

I do have that set of BR8EQ-14's I could just replace then right?

 

Yea, you could do that. Pull the old ones out, turn it over for 5-10 seconds, put the new ones in and see what happens.

 

Do you remember what size socket you used to remove the old ones?

 

Do you really need help in determing what size the sparkplug socket is???

 

might i ask to why it was you replaced the fuel filter? and when was the last time the car drove?

i just either stomp the gas and hold it down while cranking.. or unplug the lead ignitor i believe... it cuts the fuel pump, then crank it a couple times, and IF all else fails pull the plugs and crank it a couple times.

iver had to do one if not all of those before when i flooded the car. are you using the choke? when starting? maybe try it without that if you are. or with it if you arent. youd be amazed at how many people dont know WTF a choke is and what its actually for...

 

The fuel filter was solid black.
I'll post pictures tomorrow.
The last time I drove the car was Sunday, April 1.

Yes, I have put my foot to the floor while cranking, and yes I have used the choke, and I have tried not using the choke.
And yes my entire family knows what a choke and what it's used for. :P

 

A question still remains unanswered.
What if it's not flooded and there is a air bubble stuck in the lines, what then?

 

[QUOTE=Redliner223;11049760]A question still remains unanswered.

air in the lines? not really an issue man it will get pushed threw in seconds...not like a brake line where its sealed with fuel its a non issue. how long did it sit before then? sounds like the car sat if the was filter black...

 

what makes you think its flooded? does it smoke when you crank it?

 

It cranks but that's all it does.
The car sat for 20 years with only 300 miles on it.
The majority of the driving was done overall in a 7 year period with a lot of long distance trips ( little over 80,000 miles total), due to my father being in the military. The filter was last changed..... maybe 18 years ago..... when I was born. He only touched it after that was some body work and reconstruction of my right fender.

 

hmmm.... to be honest if your SURE fuel it getting to the carb i dont know... my car sat for 13 years and the tank was filled with RUST like you wouldn't believe... all my knowledge it related to FUEL problems.. so... idk... are your ignitors are good? im not much help lol

 

Yeah, everything is just old, most likely rust in the tank, and all that fun stuff.
It's not rusted out or anything, that was one thing we were good on, keeping fresh fuel in the tank, but it should be cleaned. Everything operated properly, Wednesday I'll pull the plugs and crank, then replace them with the plugs I have lying around. Then Saturday or Sunday I'll turn our house into a ninja with a smoke bomb.
I just need school to end and money to jump into my pocket.

 

reason i ask is cause theres a strainer in some pickup lines in the tank and if its clogged.... you will have problems. and running the car with rust ithe gas will spoil the carb and youll be toast for sure...

 

What AJ said, just spin it over with the starter. I don't recall exactly which fuse is the fuel pump - consult the fuse block cover (under the driver's side dash, if you don't know already, or consult a service manuals (see my signature for PDFs online.)

 

BTW, as far as money jumping into pockets? I'm over 40 and that still hasn't happened yet...

 

Thanks Kevin.
I was extremely tired when I read your first post, but now I understand what you're saying.
Tomorrow I only have one class in the morning so in the afternoon I'll have an update.
Will get pictures of the fuel filter up in a little bit.

 

Took a lot longer than a little bit, but here they are.
Before taking the filter off and having the gas take away some of the dirt on the outside, it was covered in a solid black coating. Whats left of that coating can be seen on the first picture.
Back in the day this used to be see through.
Fun stuff right?

 

Update: nothing

Won't start still. Will try again on the weekend.
