I would like to test the throttle position sensor

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

Cruise control stopped working

check brake switch under dash above the brake pedal. See if sensing wires are broken . or if it uses a duplicate switch sensor check it is engaging properly. Also check you tube on possible failures. Also in the engine bay the cable from the accelerator petal will attach to the trottle on the engine. Check for another cable at this location from the cruise control and check the cable is not broken . Check brake globes are functioning and are not blown as well.

1985 nissan 300z wont crank

When you switch the ignition wont start or crank, right? but did you hear a tikiting sound? if you do then the problem was your starter, either the solenoid in your starter was faulty or the starter itself might be grounder or shorted.Replace the solenoid if deffective or starter but before you do that check your battery.Next is to check your electrical line from the ignition to the starter and also from your battery going to the starter, if there is a connectivity it means your line is good.Next you said it has to be push to start and run but when you shut it off it wont start? It means your alternator was not charging properly, so it was deffective, the battery lost its power. replace or repair your alternator.Hope this will help you, good luck!!!

Am looking for a ecu A18-631-504 for my standard-Does this number have to match exactly-found one but last 3 numbers are different

Go to nissanpartpartsdeal.com Enter your VIN from your car registration. Go to Engine Electrical. Go to Engine Control Module. It will bring up the parts schematic with the part number for your car. That should tell you what you need to know.

What else can I ck-sounds like something so simple keeping my car from starting.

You have a lot going on here , let's clarify a little ! The engine cranks over when you turn the key ? You sure have been busy replacing parts ! If it cranks over did you check for spark at the spark plugs ? An did you test for fuel pressure ? an does it have compression ? No Start Diagnostic Basics EricTheCarGuy

My 1985 nissan 300zx stays

There are only a few things that could cause this to happen, you either have a bad distributor, badn cam sensor, crankshaft sensor, O2 sensor, or MAF-mass air flow sensor. You can cycle the key on and off and the check engine light and PCM will flash out codes, this is the easiest way to diagose the issue, and will save you a lot of time and money. I would recommend that you disconnect and reconnect all of the connections to the above sensors as this can happen from poor connectivity. If you rev your engine will it stay running?

Ac fan doesn't blow hard enough 1985 300zx

If very little air comes from the vents, the fan on the blower motor may be damaged, or there may be a restriction in the vents, or a blend door may not be open completely.

Where are the points located in distributor cap of 1985 300zx-will this keep car from starting?

Remove rotor button and points are underneath. Usually capacitor is what fails and prevents starting. It is also located with the points. Replace both (cheap!) and adjust points and you may have a fix. If not, check are you getting fuel delivery? Do you have spark at the plugs?

Won't start-just makes a whining sound even with brand new battery

Most likely your starter is bad, Take it in to any part store and they can test it for free. Also make sure the wires on the starter are tight

I have a 1985 nissan 300zx i installed the battery

Check your fuses. You probably just blew a fuse. Worst case scenario would be your ECU is burned out, which is highly likely if the fuse didn't blow quick enough. I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514
