I just got my 85 mazda rx7 gsl-se the motor doesn't run the body is in great shape i just can't figure out why it won't run. The engine rotates though. I need some help. The carburetor works right. I just can't seem to figure it out. The car has no modifications in it. And hasn't ran in years

 

does it have spark? does it have fuel? does it have compression?

 

Yes yes and yes

 

the GSL-SE isn't carbed, so first you'd need to be a little more specific about the car.

and you CANNOT have all three of those with an undisturbed car and it not run. check again.... those 3 basics are all an engine needs. verify the plug wires are in the correct order first, but it would still pop, fart, hiccup or do something.

second i would spray starting fluid in the engine to see if you in fact have proper ignition, pointing to a lack of fuel somewhere somehow.

then i would change the spark plugs, regardless if you think they are firing fine.

lastly, do a real compression test with a gauge, not by ear. if it is less than 80psi evenly with a minimum 200RPM cranking speed, you have a serious problem on your hands.

 

Okay it has a carburetor because the previous owner swapped in a carbureted engine but i will check that stuff that you said.

 

did you ask if the car EVER ran?

 

It did two years ago

 

alright, then check those things to verify. i hear people say they have fuel, compression and ignition all the time and always come to find out something is missing.

 

I'm back i tried the lighter fluid bam starts right up and shuts off and starts back so i guess its fixed for now thanks for your help

 

And i cleaned the spark plugs

 

good luck, change those plugs regularly

 

sounds like a bad fuel pump, clogged filter or fuel pickup, clogged line, bad fuel pump relay or inneed of a carb rebuild.
