2002 tracker what causes it to stall out going down the road....it acts like its missing out and dies


What engine does it have ? 1.6 L , 2.0 L , 2.5 L . A crankshaft position sensor , coil pack , I would say that you have an ignition system problem . The only way to know for sure is have it checked .Go on youtube an check out some videos on trouble shooting ignition systems from scanner Danner ,he is a teacher of automotive engine electrical diagnostics . Then go to www.bbbind.com/ for free wiring diagrams an do some voltage tests. The PCM uses reference pulses from the CMP sensor in order to determine engine speed. The PCM cannot operate the ignition system, or the fuel injectors, without the engine speed signal from the CMP.
The ignition coils supply spark to 2 engine cylinders, and spark plugs, at the same time. When the PCM signals the ignition module to interrupt the current flow in the primary coil windings, the electrical field around the primary coil collapses and a high voltage is induced in the secondary coil. The secondary coil voltage travels simultaneously from both coil output terminals, to the spark plugs, and across the gap of each spark plug to the engine block. The CKP sensor signal is used by the PCM for engine misfire detection.

What is order of troubleshoot for cylinder misfire P305?


Possible causes
- Faulty spark plug 5
- Clogged or faulty fuel injector 5
- Faulty ignition coil 5
- Fuel injector 5 harness is open or shorted
- Fuel injector 5 circuit poor electrical connection
- Ignition coil 5 harness is open or shorted
- Ignition coil 5 circuit poor electrical connection
- Insufficient cylinder 5 compression
- Incorrect fuel pressure
- Intake air leak
What does this mean? What does this mean?
Tech notes
The P0305 code means that the cylinder 5 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 5. If the problem persist more tests needs to be done to diagnose problem, see "Possible Causes"
What does this mean? What does this mean?
When is the code detected?
Engine Cylinder 5 is Misfiring.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation
P0305 Jaguar Description

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

2002 CHEVY SIVERADO NO SPARK


check at the key lock and cylinder and the ignition switch, GM has had a lot of issues with this problem on a number of vehicles. The coil pack needs to receive the signal from the ignition to complete the circuit, if no signal from the switch, it will not produce any codes and cause a no spark issue. I would start with testing the switch with a multimeter for a resistance reading.

2002 ford escape 3.0L DTC P0305and P0306 what would you ck


P0305 - Cylinder 5 Misfire Detected
P0306 - Cylinder 6 Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, The Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

Possible Causes:
- Improper spark plug at cylinder #5 and #6
- Insufficient compression at cylinder #5 and #6
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #5 and #6
- Fuel injector #5 and #6 may be faulty
- Intake air leak at cyli

Possible Solution:
- Perform Injector Service
- Replaced Spark Plug #5 and #6
- Replaced Injector #5 and #6
- Replaced Ignition Coil #5 and #6

Hope helps.

How do I replace the ignition coil in my 2002 ford taurus



Removal & Installation

3.0L (VIN S) Engine

  1. Disconnect the negative battery cable.
  2. Unplug the engine control sensor wiring connectors from the ignition coil and the radio ignition interference capacitor.
  3. Tag and disconnect the spark plug wires from the coil by squeezing the locking tabs, then twist the tab and pull upwards.
  4. Unfasten the four ignition coil retainers and remove the coil and the coil ground wire the radio ignition interference capacitor. Save the capacitor and coil ground wire for re-installation of the coil assembly.
  5. Wipe the coil towers with a clean cloth dampened with soap and water. Remove any soap film and dry with compressed air. Inspect the coil for cracks, carbon tracking, dirt or damage and replace as necessary.

    Fig. Ignition coil assembly mounting-3.0L DOHC engines


To install:
  1. Place the coil, capacitor and the coil ground wire onto its mounting location on the right hand valve cover.
  2. Install the coil assembly retainers and tighten to 45-61 inch lbs. (5-7 Nm)..
  3. Apply dielectric compound D7AZ-19A331-A or its equivalent to the spark plug wire boots.
  4. Attach the spark plug wires to their proper terminals on the coil and make sure the boots are firmly seated so that the locking tabs engage.
  5. Attach the engine control wiring connectors to the ignition coil and the radio ignition interference capacitor.
  6. Connect the negative battery cable, start the vehicle and check for proper operation.

When my SLP light comes on, my 2002 Altima will not accelerate. When it goes off the car operates fine but the check engine light stays on. what does the car need if the SLP light comes on from time to...


On many nissan altimas I have found bad ignition coils. Usually one bad one will creat a problem. The slp gets gounded through the ignition coil. When the ignition coil is going bad it shorts out other systems. Go to autozone or use a method to retrieve check engine light. If i knew the code it would be helpful. When the car is running rough disconnect one ignition coil with car off. Restart car. If car runs worse that means that coil is good. repeat process. If you have one coil disconnected and the car runs the same that means that ignition coil is not sending spark to your spark plug therefore creating a misfire and making your car run rough. That check engine light is most like likely linked to your slp light. If you find a bad coil using this teqnique replace it, your car will run better. I would like to know your check engine codes and this will determine problem better. If you have a misfire code or a po1300 code that points towards a bad coil

Replaced clogged 2002 grand am inline fuel filter. Engine turnes over and attempts to start but will not crank. The engine is receiving plenty of fuel. Could the computer- ized engine timing be off? If so,...


try drying out the plugs possibly flooded,, if its flooded try drying the plugs out and let the engine sit to dry the cylinders out.. the timing never goes out on computerized ignition, replace the plugs and ignition wires and test the coil resistances. 3 coils test between each coil where the ignition wires go KEY OFF, they should be 5 to 6 thousand ohms each if not replace the bad coil.. also did you pinch the fuel line check it for kinks ...good luck

2002 Chev Siverado,2500hd duamax dielsel. Changed the two batteries becuase the others died. Now I cannot start the engine. The engine truns over good. The security light flashes.


It sounds like the anti theft pass key's have most it's memory and needs to be reset. Try this, it takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help
