OK UPDATE
i rewired the system and found that the solenoid was keeping the system on
i removed the solenoid and rewired the stuff
so now the signal goes from battery to relay to pressure switch and then turns the pump on
which makes the water spray.
but i have a small problem
when we dynoed the car it made less power than before
could this have to do with the trigger switch activating at 0.3 bar and using 50/50 water methanol.
oh yes its a shurflow pump.
also my car has gotten some erratic boost problems since first installing the kit
even with the whole water system disabled the car surges and is erratic on part throttle.
i have a 2004 astra coupe turbo.
any ideas
