I still think this is a timing problem, most likely with the crankshaft sensor. However, it could also be in the throttle positioning sensor, since you had raised the idle to get it to work momentarily. Also, the mass air flow sensor cannot be ruled out entirely. I would start with the crank sensor, then the throttle positioning sensor. Try these and let me know.

    The throttle positioning sensor is located on the throttle body where the throtle cables connect. The crank sensor will be on the block below the heads, I'm exactly sure of the exact location on these, but the service dept at your local dealer can tell you.

Just got a1986 300zx starts with a push button start runs ruff when driving unless I turn the key to the start position run normal for a few then starts to backfire. Any idea what

Since you are a DIYer, I highly recommend you invest in a repair manual from your favorite parts store, or barrow from library, or
try if they have it, or
DIY auto salvage yards have an interchange terminal. You can search Ebay for the replacement part and it will show all models the part will fit. Backfire, Timeing some where. Either spark system or more likely Valve. Or the Air mass meter is bad. I had a bad one and it ran terrible.

I would like to test the throttle position sensor on my 1985 300zx, where is this located. I have been having trouble starting the car and keeping it running once it is started. Also when gas pedal is not...

the throttle position is bolted on to your throttle body, you should check your air flow meter also, the ecu, located behind the passenger kick panel, has a self diognastic mode with all the code definitions listed on the ecu, if i remember correctly turn the key on , dont let starter engage, pusk gas pedal to floor, release, then the ecu will bling red and green, two red blinks and one green means code 21 and so on

Sounds like the warm start choke. It positions the carb butterflies when the car is warm and adjusts the fuel mixture.

91 Nissan 300zx weak grinding start.

Text from Nissan service manual troubleshooting section:
Step 1: Check to insure battery is 100% check voltage output. Should be up there at least 10 volts.

Step 2: Check starter

The guide continues, but one of these is your problem if your engine and system run fine after engine start.

The timing is off, hence, the backfiring. This could be the crank shaft sensor, coil packs, or the timing belt has slipped.
