i just bought an sr20det engine for my 91 240sx. i got the motor in the car with the new ecu and transmission and all of the wiring is done, but im having a problem with getting spark. it is only sparking from the coil pack that is closest to fan, and the other 3 have no spark. was wondering if anyone could please help me out. thanks billy

might just need new coils

he might be right but your lucky that 1 is working so can test out this theory just take the known good coil and plug it into the other coil wires to see if it sparks. if it does u need coils if it dosnt there is a wiring problem

only the one coil pack will spark. when i put the good one to the other wires there is no spark. so what kind of wiring problem do you think that might be every wire is hooked up how it should be.
