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!!!
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.
