Okay I've been replacing part after part on my newly rebuilt t2. Orignially I had red injectors ,but then I go the opurtunity to get some purple to injectors so I put them in. well now my car start but sputters and dies. well what I'm thinkingis I oriinally had high imp injectors. My question is are the purple ones high or low? ,adn what taht be the symptom of putting low imp on a high imp harness

 

This is found in the FAQ
What size injectors does my RX-7 use? What colour are they?
Year Engine Plug Size Colour Part #
84-85 13B NA, low square center, 680cc, orange, 195500-0900
86-87 13B NA, low square center, 460cc, red, 195500-1350
86-87 13B Turbo, low square center, 550cc, tan, 195500-1370
88 13B NA, high square offset, 460cc, purple, 195500-1350
88 13B Turbo, high square offset, 550cc, purple, 195500-1370
89-91 13B NA, high oval center, 460cc, red, 195500-2010
89-91 13B Turbo, high oval center, 550cc, purple, 195500-2020

And if I understand correctly using low imp. injectors could burn out your injector driver circuit on the ECU if left on too long. If you had red injectors before the the rebuild, Was it an NA? Good luck, Hope this helps.

BTW, Next time you might want to look in the FAQ before some search **** gets on your case. All kinds of useful **** in there.

 

I'm more of a visual person can somone get pics up

 

I dontunderstand the notch thing your talking abut. is there a part number I can get off them

 

Look at the plug for the injector, this is the notch in question. I have attached a drawing to illustrate the difference.

As far as the part number goes, it is on the side (hold the injector with the plug facing left or right) on the plastic part.

Hope this helps ya!

is there a way to tell if my hanress is high or low imp?

 

All RX-7 smade after 87.5 are high impedance.

A sure fire way to tell is to look for the injector resistor block. If there is a block, then the car is low impedance. Check the Factory Service manual for the location of the fuel injector/solenoid resistor.

 

well I ahve the resistor but it isnt connected nor can I find a connector for ti

 

did mazda put the resisitor pack in high imp cars too ,but just not connect them

 

no

is yours a t2 conversion and you ar erunning na ecuand or afm
