The timing does appear to advance when I rev it up, though, Im assuming the white line moving from 10 to 20 + is advancing or should be it going backwards towards TDC? Car rolls in neutral, brakes definitely are not sticking...
A few things I have noticed, which may be related. When I put the car into D or R (or put load on the motor I guess), there is a whinging, hissing, squealing type sound that comes from the throttle, distributor area. Not sure if this is normal... Also when the car warms up, it seems to start missing and runs really rough (also backfires if I plant my foot, esp under load). Let it cool for 5 mins and all is good again for a bit. An interesting thing I noticed today, it backfired as it was warming up and I was accelerating very slowly in D, but just after the backfire or pop under the bonnet, it felt like it had full power and was about to take off for 2 secs. But then dropped back down to 1500rpm. hmmmmmmm!
Shouldn't your timing be before top dead center, my book says 8 deg BTDC, from reading what you have says you are running after TDC, timing mark should be at 11 o'clock not 1 o'clock.this would make it retarded, and backfire. also faulty coil will do all this
Has this car been running with the auto or have you just installed it, lots of people put them in wrong and jamb the oil pump with the tork converter.
Does this car move when you try to drive or does the motor try and stall, just trying to work out if it is your auto.
I have some good PDF's here on fuel injection 280z and 280zx, that show alot about trouble shooting not sure what you have, if you want send me your email.
