just curious how much doe s a R33 GTS non running go for these days.
re the issue, start with basics
for a car to run you need spark, air and fuel.
check you have spark at each plug by removing it plug back into coilpack then hold close to the block and have some-one crank it, see if you get spark.
then when you first turn ignition (make sure it's quiet and no stereo on) on can you hear a small hum from boot area, ie can you hear the fuel pump working?
if not pull the fuel filter and crank does fuel come out?
past that get a lube mobile round to have a look?
