SOURCE: Need to remove aftermarket radio in a 1990 nissan 240sx

Remove the shift knob. Starting on the console around the shifter, gently pull up on the "bezel". When it comes off you'll see the radio's held in (with the little storage area) by 4 Phillips screws.
The wiring is hidden behind

92 nissan 240sx wont run after 2500- 3000 rpms changed cap and rotor new wires w/ plugs starts right after dies timing is also good


a weak coil could cause that problem
could also be an issue with the ECM / PCM
low fuel pressure caused by a weak fuel pump, clogged filter or dirty injector(s)

if you haven't tried this already then you should. get some QUALITY fuel system cleaner / injector cleaner, and follow the directions.

hope this helps.

How to fix a clogged catylitic converter on a 1991 Nissan 240sx and change the fuel pump


A pluggged CAT can`t be fixed.Visit an Exhaust shop where they can fabricate (build) a new one for you. Make sure they give you a discount for your old CAT. As for the fuel pump it`s located in the gas tank. This is not an easy task to do yourself-visit your local repair shop for an estimate and evaluation on both the CAT and FUEL PUMP..

Fuel injectors leak at fuel rail


Get some new O-rings, and this time put oil on them before you insert them into the fuel rail. The regulator is alright.The problem is that the o-rings can roll up, or twist when push em in dry. Had this problem once, easy fix, but was frustrating.

My 1993 240sx smells like gas when I drive it and it does not get good gas mileage anymore. I just had a tune-up two weeks ago and have seen little improvement. Thanks, Bridget


I am thinking that it may be your fuel injectors. You may have one gone bad or the O- rings may need replacing. At least that is what the gas smell was caused by my 1990 model.
