hi
i have an 88 n/a
ive removed my injectors from the engine(swapping engine for a rebuilt)ive checked the resistance and there at 13ohms
all 4 of them

the thing is if the injectors are ok can they still be leaking even with the right resistance????


and anybody is using DEX-COOL alumium safe colant in there rotary???


thanks alot

 

I use DEXCOOL in my REX, and haven't had any problems - the car runs at the correct temperature. There has been a lot of discussion in this forum about 'green vs. orange', and a lot of bad press about dexcool. I don't agree. Search the archives and decide for yourself.

 

yes, your injectors can still be leaking.

 

i know in the service manual they show a way to test them

do you guys know a way to test them while they are out of the car???

 

On my 87n/a I disconnect the secondary fuel rail and lay the injectors out of their bores. Put a container under them. Ziplock the injectors to the rail. Get an spare injecor plug and splice two wires to it. One wire to ground. The other with a alligator clip will go to the positive terminal of the battery. Jumper the yellow fuel connector next to the r/h strut tower. Turn the key to the on position(do not start). Take that alligator clip and touch it to the positive terminal. Fluid will flow. Take the clip off. See if the injectors leak. You can swap the primary injectors with the seconday injectors and do the same. Also you could turn them on for exactly a minute and then measure the amount of fluid and see how close it comes to factory specs. Can determine if you have 460 or 550 injectors if your confused. Go to the factory manual section 4A at this site.............http://www.iluvmyrx7.com/

 

thanks alot for the tip

by the way i think all of my four injectors are 460

 

i dont have any spare injector connector
can i just plug them with two wires or theres a + and a -

thanks

 

yes you can its just easier to wire em up with an extra cause the connector is so small hard to get any thing in therre to make contact....
