    its pretty unusual to see a bad injector. Are you sure that's the problem?What engine do you have? That will make a big difference on how the injectors are replaced!

I have a 89 mercury tracer.. the fuel injectors were bad, but when i replaced fuel injectors, car starts but then dies. will not stay idle.


I do not know what you did or did not do. Did you possibly get the wiring mixed up? Did you have new seals and lubricate them as you seated them? Are they the correct injectors. It could also be a fuel pressure problem. Why did you replace the injectors? Did the car run okay before?

Replace fuel injectors


Disconnect the battery. Ground the Injector circuit to discharge any stored energy. disconnect and remove the injector rail which should pull the injectors from the intake then remove the retaining clip on each injector to be replaced and replace them one at a time and reverse the process to put everything back. If you need further directions on removing the individual injectors I highly recommend the Haynes repair manual on your vehicle.

Trac off light came on and off then stayed on while driving, p0203p0204 p0300 codes when scanned with little machine better read open circuts in both injectors loss of power


P0203 - Injector Circuit Malfunction Cylinder 3

Powertrain Control Module (PCM) or Electronic Control Module (ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The PCM/ECM will trigger the P0203 code when the resistance or voltage drop at the injector #3 is out of specifications.

Causes:
- Open or shorted wiring harness to the injector #3
- Bad injector #3
- Bad PCM/ECM

Solutions:
- If damage, repair injector wire harness or connector
- Replace injector
- Replace PCM or ECM


P0204 - Injector Circuit Malfunction Cylinder 4

Same info as the P0203 DTC


P0300 - Random/Multiple Cylinder Misfire Detected

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

Causes:
- Improper spark plug
- Insufficient compression
- Incorrect fuel pressure
- The injector circuit is open or shorted
- Fuel injectors may be faulty
- Intake air leak
- The ignition signal circuit is open or shorted

Solutions:
- Perform Injector Service
- Replace Spark Plugs
- Replace Injectors
- Replace Ignition Coils

Best Practices
  • Using lower quality gasoline can result in recurring fuel injector problems, even after a fuel injector replacement.

  • Fuel injector seals should always be replaced along with fuel injectors.

Common Symptoms
  • Failing fuel injectors can cause engine misfiring and hesitation. The Check Engine Light may come on and set diagnostic trouble code(s).

I have a leaky fuel injector on 1990 4.0 str. six Should all injectors be replaced for safety issues? Can the leaky one be replaced by itself?


The leaking injector can be replaced by itself. There should be no safety issues to replacing only one injector.
