20 Most Recent 1994 Nissan Sentra 4-Door Questions & Answers


I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com

Take a look at the belt first. If broken suspect serious damage to head and possible piston damage.

Have your compressor check. Squeaking sound is caused by a metal to metal contact. Your compressor bearing needs to be replace, to get it aligned. So that the metal to metal contact will be eliminated. Reload your compressor with refrigerant, before getting it activated. Replace the burnt wiring and the relay. Since a lot of work must be done, it is suggested that you take this to the car aircon service
center.

Sounds like the fuel pump is failing, have the pressure checked at start up.

could be a poor ground. check the ground wire on the battery, battery to engine, and battery to body. remove the wires and clean contact points, reassemble with dielectric grease. Trailer lights will act this way when there is a poor ground contact in wiring plug.

run the fault codes and look for failing sensor (probably in the accelerator position area)

On the 94 sentra the fuel pump relay is located under the hood, driver's side to the left of the battery, third slot from the front of the car, should be green in color.

If you follow your brake pedal up to the brake light switch, there is suppose to be a little round semiclear button which fits in a hole opposite the brake light switch this is the most common problem on Nissan products when the brake lights don't go off, the buttons break and fall off. I haven't found an after market supplier, but the dealers keep these buttons in stock. They are very cheap. When you get yours providing it's not the brake light switch, us a little dish washing liquid, position the small end of the button in the hole, they usually have a little bit of a point on them (it is nearly impossible to push in by hand and you really shouldn't use pliars.) Anyway, With it in position, hold it in place and let the brake pedal come up against it. Pull back on the brake pedal torwards you and it will pop right into place. If its a bad brake light switch and the button is still there, take an ohm meter, unplug the switch and touch one lead ot one of the wires coming from the switch and the other lead to the other wire. The ohm meter will tell you that there is a complete circuit when the brake pedal is in the upright position. Good luck.

check the sender. first.
unplug it.
10 ohms full or about 200 empty.
interpolate to find yours, based on how full it really is....
sure, we both dont know. but I check mine with a dip rod like on aircraft. (watch the C130 flight line)
some cars have have a check valves as the filler neck reaches the tank , making rod checks impossible. dang.
i use a 2 foot long thin metal rod.something that can break.
if the sender reads, INFINITY it is Bad. (at sender pins, sure)
