i have put new injectors in it

so its getting gas and its sparking

and it dosent have a compressin leak

what else can be wrong?

please help this is my first rotary

Check gas pressure to injectors. The fuel filter can be partially blocked, or the fuel pump defective. Getting spark does not indicate the spark is occuring at the proper time. Check timing. Last resort if all checks, check compression, The rotory requires a special compression testor of a procedur burried in the club archives.

i checked it and the fuel pump is good,the filter is clean,and there is pressure to the injectors

i dont know about timing and compression but it runs if you spray ether in it or prime it with gas but it wont stay runing on its own

Probably flooded.

Read the FAQ for FC sticky thread found at the top of this (the 2nd Gen RX-7) Technical section.

No offense man, but if it was flooded, why would squirting fuel into it make it run?


Are your fuel injectors clicking like they should be?

87rx7girl

is the starter cranking.
it could be flooded. i had mine flood. it took 2 days to clear everything out even with fuel shut off switch.
take your plugs out. pull egi fuse. turn off your fuel pump if you have that switch installed.
clear out the chambers. let it sit over a few hours. clean your plugs a bit with carb cleaner. make sure they are dry. toss them back in. if you have a fuel switch. put your egi back in and try starting it. if you dont have a switch. have a buddy hover over your car ready to put the egi back in. crank it over a few times. then try putting the egi in or flipping your switch while you are cranking. it might start right up.

Try jumpering the fuel pump check connector. Sounds like you are not getting fuel.

I assume your ENTIRE intake system is intact from the AFM back, correct?

shpaintball

starter?....try push starting it and if that works well its the starter/ or a tranny sensor

Icemark

because of this comment:
Ether/starting fluid evaps quick and helps clear flooding

RoTa7

yup icemark reads everything before he post.

i listened to the injectors and they are not clicking how do i fix it?

HAILERS

The Primary fuel injectors are under the intake manifold. I doubt you could hear them clicking if the starter is turning the motor over.

Get a meter out (no bug light, please) and see if there is 12v on one wire of the secondary injectors. Secondary injectors are visible on the right side of the engine.

And, if the fuel pump check connector is jumpered and key to ON, can you hear the fuel being returned to the tank? NOt the pump running, but the fuel being returned to the fuel tank. As in splish splash.

maybe.........the sparkplug wires are mixed-up. or not. i'm just guessing.

micah

Did you even read the thread?

Did you recently complete any major work in the engine bay that could have caused you to mix up the fuel lines, injector connectors, or anything else?

If this is just a random occurence, de-flood and move on with your life.

micah

Mother of god.... If his injectors aren't clicking, and when he adds fuel it starts...... How, in Zeus's Butthole, can it be flooded?

You were off to a good start until you mentioned flooding.

Read BEFORE you reply.


I have a question for the pros... HAILERS, J-Rat, Aaron, etc...
When you pull the EGI fuse, do you still get spark? Just thinking that this is probably a fuse, wire-loose, or bad ECU.

i dont know about any of the electric stuff

by the way im just 16 years old and just got started in all of this rotary stuff but i have a good feeling that micaheli is pretty smart

and to alexdimen i dont know if its a "random occurance"...i just bought the car

blackdog91n/a

well thanks for your concern guys but i found a runing s5 which is what i have and it has a turbo on it so im gonna change the whole thing

but that raises a second question: what would be better, like i said im new so i dont know a lot of termenology

would it be better to get a raised hood for the cooler thing or get the big radiator looking thing in the front?

i guess ill keep the old engine for parts...or a go cart lol jk

micah

I wouldn't go that far.

Hey i'm in ky too, if you need any help just ask. Not too far away.

http://rotaryresurrection.com/2ndgen...to_turbo2.html

That will help you if you want to do a turbo swap.

Also check out ludwig motorsports, he is a member on kyrotary.com and you can ask him questions about rebuilds and porting and engine swaps.

But to get it to run, check your fuses. I would put my money on that before anything else. Since it isn't a S4 the AFM doesnt turn the fuel pump on or off.
