so i found what i thought is a good deal on a 1990 model 300zx na car but recently has had a jdm swap tt out of a 95 jdm 300zx... said when it was put together it pulled hard, drove good, and was his daily... bought a new car didn't drive the z anymore... went to start it one day after sitting for a while, and didn't start.... lost his job and now it has sat for 1.5 yrs body is very nice, one little spot of surface rust on top of hatch but that could easily be re sprayed....

went to look at it today and i like it bt im not a z guru, so i need your help here...

put my battery in it, tried cranking it, didnt start.... it tried to start like if it was out of gas but never started... ok so i had the key in the on position and loosened the line from the fuel filter off to see if it had any fuel pressure and it had quite a bit of pressure. my next guess was the injectors, so i had a buddy of mine try to crank the car while i tapped on the injectors tring to break them loose of any gummed up gas..... nothing, went to local parts store and bought some starting fluid, sprayed fluid through both tbodies and had buddy try to start again nothing..... looking at the motor the guy spent some money on a nice engine harness, looked like nothing was hacked nor unplugged....

any solutions guys.... im no mechanic but ive built some nice cars but never fooled with a 300zx... could it be a cam sensor? it looks and sounds like its not getting any spark now, well to me it seems that way if its getting fuel and not starting my next guess is spark...

please help me, i would like to get this car, the gy doesn't know what he actually has and its to good of a deal to pass up....
