1991 Nissan Maxima Questions & Answers
My speedometer won't go above
check out both (output and input speed sensors), as well as (both connectors); do this first. Next, remove instrument cluster, and replace coil-spring that operates speedometer needle ( has tendancy to go back at anytime).
Where is the speed sensor located on a 1991 Nissan
the speed sensor is on the the tail housing of the transmission, located by the firewall straight down from the back of the engine, it is a round looking sensor on the top of the housing has a 2 wire plug with about a 8 in. lead, but it may not be the problem, I have one also that I think is the speedo itself, this sensor sends the signal right to the speedo and then the speedo have a processor that sends the signal to the ecm.

My 91 Nissan Maxima when idling in park or nuetral revs up and down
Check for any air leaks between the mass airflow meter and the engine like the rubber being split on the air intake boots etc.. I once had a toyota that would do the same thing and the fix for that was to flush the coolant passages in the throttle body, worth a try. Also you said you replaced the TPS. If the TPS has slotted holes you must set the minimum TPS volts or that can also cause idling issues. Clean the throttle body as well.
WHY DOSE MY DASH NOT LIGHT UP WHEN HEAD LIGHTS ON
There is usually a dimmer switch for the dash lights near the left side of the dash behind the steering wheel. Sometimes that can get bumped when you get in the car and turn the dash lights completely off.
Car does not start. No spark coming from ignition coil
If the starter works and there is no spark at the ignition coil, replace it. Check your center electrode wire too. A new distributor cap and rotor may be in order as well. If that doesn't fix it, your distributor is shot.

Don't attempt it. It is not for the DIYer. There are very detailed procedures to follow and getting the timing right is is tricky. If you do attempt it buy a good manual and follow it closely.
