Just wonderring how many 300zx owners post on here?? I just bought a 1990 300 that doesnt start and could use some advice.. Its been sitting for a year or so and is not getting any spark.. I have changed the gas, sparkplugs, cleaned all the connectors I can see on the motor, and changed the PTU.. the ECU reads 33 (O2) and 21( ignition circuit).. Any help would be great..
