Hello all. I have just ripped out the old spitronics Venus and installed the storm.... however it wont start. its a 1990 1uzfe with an M112 supercharger running K20 cops When I crank it over it will not fire at all until I stop cranking and then I get a backfire, I can smell the fuel. all injectors are clicking on test all ignitors test well with strong sparks when on test but do not spark when cranking.....? engine speed reads around 170rpm on cranking and I am getting a green box for triggers 1 and 2 I have around 8 to 9 volts at the ecu when cranking (too low maybe?) the base map supplied with the ecu was for a vvti 1uzfe with boost but I have the non vvti engine , would this be a problem? I think my backfire is because when I turn off the ignition the ignitors spark due to the field collapsing maybe I have entered the unlock code supplied and my status says enabled ecu the ignitors are set to direct spark, is there another way to turn them on or off? im getting a new bigger battery tomorrow as my old one doesn't seem up to the job but i'm doubting that will be the problem but you never know. the spitronics wouldn't start unless the battery was fully charged. Base map and a log of the cranking are attached if anyone can help. Any ideas are very much appreciated at the moment, im really looking forward to hearing her run. Many thanks Rod Log 2019-03-31 3;42;36 pm.llg base map 1uzfe.pclr
