Question about 1986 Nissan Pulsar

1 Answer

Electrical problems My Nissan Pulsar Nx 1986 has a problem with electricity. The engine starts working and in a few minutes it stops working. Many mechanics are not able to solve the problem and I had to buy a new engine in USA and I Substituted the old one but the problem still occurring. People told me that there is, may be, an electrical problem once the car is an electronic one. But we did not have any way to verify the electrical fault and I don?t know how to solve this problem. Can you help me?

    Thanks. I agree with your solution and I think the problem is with the distributor. Can you explain me how does the pulse generator works? It can be placed or not? How to get it? Can you assist me with any of these components?

Hi jantopina,

i was able to work for a 1986 pulsar before and you know what, we were able to trace the problem to the distributor .

the distributor is an electronic part and it uses a plate with slots and these slots passes thru a LED and a receiver to indicate a pulse. the problem with these electronics are temperature.

as the engine heats up, these diodes would not emit light or would not receive light that is why the engine would stall because the spark would not come out. after the diode in the distributor, there is also a big metal transistor that triggers the ignition coil. sometimes this transistor also malfunction.

we were able to trace the problem by using special tool like the pulse generator and the pulse sensor.


tnx 4 using fixya,

    pulse generator is just a simple tool that would replicate the distributor signal so we were able to troubleshoot the problem more precise but it did not solve the problem until the distributor was replaced.

    tnx again,

    please dont forget to rate the solution,

That's the way it works.
You put the key on , pump goes few seconds and stop(building up the pressure).When you crank the engine it start going again.

Nissan pulsar '88. replaced starter motor, then


Is it a manual, or an automatic? Earlier Nissans sometimes have a problem with the neutral safety switch (a device that keeps the engine from rolling over in gear or without the clutch depressed.) Generally, if their bad, they need to be a little warm before they'll start, like setting in the sunlight for a few hours.

Good Luck!
