Hi I’ve got a 91 3000gt vr4 twin turbo and one day it was running perfect and I shut it off 10 mins later it wouldn’t start at first I thought it was fuel but it’s not then I checked sparked and there’s none I replaced the ptu and the coil packs (all 3) and still the same no spark I know the ptu runs 2 things the rpm gauge and the coils packs on/off and since I’ve owned the car the rom gauge has never worked but still I replaced them and still have no spark any ideas please help

 

Your ECU could be faulty - did you open it and do the capacitors look OK?
