Ok folks if you saw my other posts I was having problems getting my car to run correctly. So here is what I found



I checked the coils, everything works correctly. I removed the CAS (Crank Angle Sensor) assy. from the front of the engine, turning the ignition to the on position, I turned the gear by hand and checked each spark plug for spark. everything was good. I checked the wiring diagram and found that the coils control the fuel injectors as well. So as I turned the CAS, I could see the leading and trailing plugs firing for both rotors, but was only hearing one click from the primary injectors. I checked in the Haynes manual and found that there is a resistor pack located right behind the passenger headlight on the strut tower (long silver unit with a football shaped plug) The Haynes manual says to test the unit on two of the pins and there should be a 5-7 ohm reading, I got zilch... So tomorrow I go search for a new resistor pack, hopefully this will cure the no power problem.



Any one ever have a bad resistor pack?

ive never seen it, but its possible. if that thing was an open circuit the car wouldnt run. you know the resistors you guys wire in the car to do 1600's? this is mazdas version



mike

well it runs, but onl'y on one rotor...



rotor one is good, plugs are all nice and charcoal/black from a proper burn, the rear rotor, they look brand new, except for minor oil injection film I am not getting excessive richness or fuel or flames and the engine is lacking severe power, but it does run, it does get up to 60 mph, just takes about 4 miles to do it :P

Good to hear you got it figured out!

hmm so its like not getting fuel on one rotor? that could be the resistor



mike

Yeah mike, no fuel on the rear rotor. I should have a replacement resistor in a few hours, I'll update on the results

well I can;t find one, looks like I may have to go to Mazda to finally get one :(
