Question about 1988 Nissan 300ZX
My 94 300zx just wont start have changed crankangle senor and ptu also ecu no luck car turns over very well and still no luck getting plenty of spark plenty of fuel all wireing seems fine starter has been changed also got it pluged into a dianostic machine it came up primary ignition circut error any ideas as to wats wrong before i brun my car ps. no vac leaks I have a similar issue, i have replaced the PTU / Injectors / Coils / Ignition / ECU -- the list goes on... What i noticed in my z, and quite frankly i dont know if it helps, is that the aftermarket security system i installed ran on the primary ignition circuit. I noticed that the clips have come undone and so i'll be looking into it on my days off and see if i can figure it out. Just a thought, i'm not an expert but again i hope it helps

check timing, see if belt may have slipped out of timing, and need pressure tester to test pressure where the fuel goes into the fuel filter. check for vaccuum leaks.
