    Default Dicktator wasted spark on a 1uz - HELP!!

    Any help regarding Dicktator wasted spark ecu wiring and potential problem will be greatly appreciated.
    Just collected my new Toy, a '88 FJ45, coverted to a troopy at some stage of its life and in about 6 years ago had a 1 uz fitted.
    I brought it back to Jhb and had a look at starting it earlier. No Luck! So I started checking the wriring and opened up some of the shoddy looking tape job to find a few dodgy connections and some PC boards taped up between some wires. Any ideas on what they are for, or if they should be there at all.

    When the ignition is turned on, there is a red light on at the ECU. While cranking, there is a green light that flickers as well as the constant red light, but will not start, though giving a hint for a second, at most, sometimes.

    Was told that the engine last run in February and been parked off since then. Did put fresh fuel and it has a new 6.5 bar Femo fuel pump.

    Did notice that the fuel pump does not sound like it slows or stops once the ignition is switched on. It continues to pumps no matter how long it is left for..

    Any and all help will be greatly appreciated. 1st prize would be a fundy to possibly swing by over the weekend and help a desperate somebody?!?!?!

    Before digging into wiring harnesses do the basic checks. See if you get spark at the plugs. Remove a plug and check if it get fuel or not.
    One side of the injectors get 12v + from the main relay. Other side pulsed by ECU.

    A wiring diagram from Dicktator will help. You also mentioned that it stood for awhile without being started. You might have lost the program if the battery run flat as well as the Dicktator back up.

    It is not what you buy its what you build.

    Okay, so I got the Lexus running. It was a combination of bad fuel, varnished injectors, bad plugs and a short to positive on the pulse line from the ECU. So now she purrs like a kitty and snarls like a lion when asked to.

    She is however over fueling quite a bit. Does anyone perhaps have a fuel and ignition map from a 1UZ with a Dicktator Wasted spark system, that has been tuned on a dyno??

    Thanks in advance
