i had the same problem a month ago when it got cold up here and my car sat for a couple weeks. i was sure it was frozen summer fluid. the fluid in the resevoir(sp) was not frozen though and i was able to use the hatch washer nozzle . i had to jack up the car, take the passenger wheel and trim off. what happend was either dirt or ice was jammed it the pump. pump worked, just wouldn't shoot anything out till i stuck a needle to break up the blockage.
thread jack alert. so hows the turbo working for you falango. wish you had it on for the bc mazda meet in the summer so i can check it out. might have to meet up this spring.summer to compare turbo kits. i should be thumping my thumper kit by then
