SOURCE: IGNITION FAILURE ON 280 ZX (82)

  1. Turn the ignition switch OFF. Disconnect the fusible link connector for the fuel injection wiring harness. Be sure the ignition is OFF before doing this. Disconnect the cold start valve wiring harness connector. Disconnect the high tension lead (coil-to-distributor) at the distributor and hold it 0.13-0.25 in. (3.3-6.3mm) away from the cylinder head with a pair of insulated pliers and a heavy glove. When the engine is cranked, a spark should be observed. If not, check the lead and replace as necessary. If there is still no spark, go on with the following system checks.
    1. Make a check of the power supply circuit. Turn the ignition OFF. Detach the connector from the top of the IC unit. Turn the ignition ON. Measure the voltage at each terminal of the connector in turn by touching the probe of positive lead of the voltmeter to one of the terminals and touching the probe of the negative lead of the voltmeter to a ground, such as the engine. In each case, battery voltage should be indicated. If not, check all of the wiring, the ignition switch and all connectors for breaks, corrosion, discontinuity etc., then repair as necessary
    2. Check the primary windings of the ignition coil. Turn the ignition OFF. Detach the harness connector from the negative coil terminal. Use an ohmmeter to measure the resistance between the positive and negative coil terminals. If resistance is 0.84-1.02 ohms, the coil is OK; replace it if the reading is far from this range.
  2. If the power supply, circuits, wiring and coil are in good shape, check the IC unit and pick-up coil as follows:
    1. Turn the ignition OFF.
    2. Remove the distributor cap and ignition rotor.
    3. Using an ohmmeter, measure the resistance between the two terminals of the pick-up coil, where they attach to the IC unit. Measure the resistance by reversing the polarity of the probes. If approximately 400 ohms are indicated, the pick-up coil is OK, but the IC unit is bad and must be replaced.

  1. If the resistance is other than 400 ohms, proceed with the following:
    1. Be certain the two pin connector to the IC unit is secure.
    2. Turn the ignition ON.
    3. Measure the voltage at the ignition coil's negative terminal.
    4. Turn the ignition OFF.
WARNINGRemove the tester probe from the coil negative terminal before switching the ignition OFF, to prevent burning out the tester.
    1. If 0 voltage is indicated, the IC unit is bad and must be replaced.
  1. If battery voltage is indicated, remove the IC unit from the distributor, by proceeding as follows:
    1. Disconnect the battery ground (negative) cable.
    2. Remove the distributor cap and ignition rotor.
    3. Disconnect the harness connector from the top of the IC unit.
    4. Remove the two screws securing the IC unit to the distributor.
    5. Disconnect the two pick-up coil wires from the IC unit.
WARNINGPull the connectors free with a pair of needlenose pliers. DO NOT pull on the wires to detach the connectors.
    1. Remove the IC unit.
  1. Measure the resistance between the terminals of the pick-up coil. It should be approximately 400 ohms. If so, the pick-up coil is OK and the IC unit is bad. If the resistance is other than 400 ohms, the pick-up coil is bad and must be replaced.

SOURCE: 97 Pathfinder, I have replaced the fuel filter,

Older dated Pathfinders such as yours are sometimes prone to cracked manifolds. Have this checked immediately.

SOURCE: 97 nissan xe pickup with 2400 motor runs like grap

The ignition coil is part of the distributor assembly, weak spark will make it run bad, not a cheap part.

Quits after warm up wont restart


sounds like you have a fuel pump problem, fuel pumps will usually get hot and then shut off allowing it to sit 30 mins lets the pump cool down allowing it to start pumping, the way you can test it is get a can of starting fluid the next time it quits raise your hood and spray some fluid down into the throttle body and if it starts and then dies it is most likely your fuel pump, hope this helps.

1992 cavalier. starts and drives fine, but will die after it's been driven if i try to put it in gear again. What's the problem? bought it site unseen, drove it home about 7 miles and it started sputtering...


Try pulling the vacuum line off of the EGR valve when the engine is warm and starts to sputter. If it runs good cold and then dies when warm and won't start again until the engine cools it is most likely a bad or sticking EGR valve. Try the procedure to confirm it is the EGR. You can check the internet for location and an image of the EGR valve for your specific car. Please rate me on this answer.

Fuel pressure intermittently drops causing sputter and die.


check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

My 2000 eclipse wont start up all the way


I have the same problem on my 2002 Eclipse RS 2.4l 4 cylinder. Replaced the battery, starter, fuel pump(not at one time) . It started up when I had the starter put on as well the fuel pump. But everytime I started the car up it ran good till I turned it off the problem was still there. The car sounds like it wants to start but it sputters you can smell the gas so I know its getting fuel. it starts up fine with a cold start like in the morning.

Try getting a diagnostic thats what Im going to do next week.
good luck!!!

thers a oil psi senser that wont let the fuel pump run at low psi when the car worms the psi gos down ,the fuel rely only runs the pump for about five sec as a primer then the oil psi senser takes over thirs a plug righi behind the oil fliter for the senser ,un plug it and put ajumper wire across it as a test ,you may need a oil pump
