Question about 1990 Nissan Pulsar

2 Answers

1990 nisan n13 motor 1.6, has no spark to coil i drove car to train station, when i got back the car would not start, replaced coil, distributor, ecu box, all fuesible links, plugs & plug leads, fuel pump is working properly, checked timing belt, set timing properly, have sprayed all joiners from ecu unit to dissy to coil , still has no spark at plugs, hoping you can help. cheers barry.car has no key imobilisor unit, i am not sure if it has a crank sensor as i cant find one, or the cam sensor.

I can give you a little general help on this. With key on, the coil primary positive wire should have voltage. I think that may be a black/white wire? This is directly from the ignition switch on the run wire. If you have power there, then everything else is in the distributor and controlled by the ecu. I see you have changed the coil, the distributor, and the ecu...check the main relay, it's a power source for the ecu. The power feed to the main relay is a 25amp fuse link (see you changed fuse links, too). Is the ecu on? Key on, all warning lights, and check engine light on?

I cannot find a test procedure for diagnosis. But as I said, everything is inside the distributor. Yes, there is a crank angle sensor, more commonly known as a Camshaft Position (CMP) Sensor. Essentially the same thing, the CMP sensor sends a signal to the ecu of both engine speed and piston position reference-TDC. The ecu then determines ignition timing-sending a spark signal to the ignition module inside the distributor-then the coil sends spark. The sensor has a rotor plate with 360 slits for 1 degree signal (angle signal) and 4 slits for rpm signal. Has a light emitting diode and a photo diode to catch the signals...it's all sent to the computer. Maybe you got a bad distributor?

Your car has both a crank and cam position sensor. First start with your crankshaft position sensor. It is located by the harmonic balancer on the front of the motor.

SOURCE: hi my nissan pulsar n13 misses at about 1500 to

Try taking your air cleaner cover off, and rev the engine to about 3000rpm, put a clean lint free cloth or your hand over the mouth of the carburettor and the engine will die. Try to keep it going for about 10 seconds at about 1500 rpm and take the cloth away until it runs smoothly again at 3000 rpm. Air cleaner back on and see if that makes a difference. It is an effective way of clearing jets that are not too badly blocked.

1991 n13 nissan pulsar 1.6 liter motor I have just replaced the distributer and coil but I am still gettin no spark what do I do


Did you even bother to check and see if the distributor and coil had any battery power to work with before you blamed them for the problem and sent them to their grave? I'm So-o-o-o-o glad I'm not an auto part....No such thing as a fair trial where facts must be presented and proven before you can be locked (thrown) away......

It could be anything in the ignition circuit, including the ignition switch itself or a break in any of the many wires involved....Proper diagnosis required.

Please see my tip at http://www.fixya.com/cars/r6223989-ignition_coil_doesn_t_spark . These are generic instructions--specific instructions are pasted below from Autozone.com. If you get stuck, please get back to me.

Use a test light to check for power to the coil on the black wire with a yellow stripe--see procedure below and other tests you can run. You will need a volt-ohm meter to run most of these tests.

The system used on 1990-95 Accords and 1989-95 fuel injected Preludes uses the distributor components to signal the engine computer. The ECU triggers the spark through the igniter unit and coil. This spark timing is controlled by the computer as an integrated function of the fuel management system. The distributor contains a crankshaft angle sensor and a No. 1 Cylinder Top Dead Center (TDC) sensor. Using these and other electrical inputs, the computer controls spark timing electrically.

1990-91 ACCORD
See Figure 6

  1. Remove the distributor cap, rotor and shield.
  2. Label and disconnect the 4 wires from the igniter unit.
  3. Switch the ignition ON . Use a voltmeter to check for voltage between the black/yellow wire and ground. Battery voltage should be present. If the voltage is not present, check the black/yellow wire between the igniter and the ignition switch.
  4. Check for voltage between the white/blue wire and ground. Battery voltage should be present with the ignition ON . If voltage is not present, check the white/blue wire from the igniter to the coil and test the ignition coil.
  5. Turn the ignition OFF . Check for continuity in the yellow/green wire between the igniter and the ECU.

Fig. Fig. 6: Terminal identification on 1990-91 Accords

  1. Check the blue wire for continuity between the tachometer and the igniter.
  2. Check the resistance between the terminals which connect to the blue and white/yellow wires. It should be between 1,100-3,300 ohms. If not, the igniter must be replaced.
Coil test:
1990-91 ACCORD

See Figure 16
  1. The ignition coil is contained within the distributor. With the ignition OFF , remove the distributor cap.
  2. Remove the screws securing the black/yellow wire and white/blue wires from the terminals. The black/yellow wire is connected to the primary positive terminal and the white/blue wire is connected to the primary negative terminal.
  3. Measure resistance between the terminals. Resistance should be between 0.6-0.8 ohms.
  4. Measure the resistance between the primary positive terminal and the secondary terminal. Resistance should be 12,800-19,200 ohms.

  1. All test conditions must be met. If any test condition is not satisfied, the coil must be replaced.

Engine turns over but doesn't ignite.


I would check the coil and coil wire. Check for spark from the plug coming from the coil. Also check your distributor rotor and cap.

No Spark


There can be a couple of causes for no spark.
Common problem - Ignition unit in distributor has failed - Replace distributor.
Common problem - Coil failure - Replace coil.
Common Problem - Stuck ECU relay - indicated by no pulsing of injectors and no spark - replace relay.
