1996 Isuzu Rodeo won start. 2.6L 4cyl. Not getting fire. Have replaced distributor, ICM, Crankshaft Position sensor, ECM/PCM. Fuel pump not bad, but no noise when trying to start. Any suggestions what to check next?

There are a few possible causes for a 1996 Dodge Stratus 2.4 4cyl. engine not starting and experiencing a lack of spark or injector pulse:

1. Faulty ignition switch: The ignition switch is responsible for activating the electrical system when the key is turned to the "on" position. If the ignition switch is faulty, it could prevent the engine from starting.
2. Failed crankshaft position sensor: The crankshaft position sensor is responsible for sending a signal to the engine control module (ECM) indicating the position of the crankshaft. If the sensor is faulty, it could prevent the engine from starting.
3. Failed engine control module (ECM): The ECM is responsible for controlling the engine's ignition and fuel systems. If the ECM is faulty, it could prevent the engine from starting.
4. Failed fuel pump: If the fuel pump is not functioning properly, it may not be able to deliver fuel to the engine, causing it to not start.

To diagnose the problem, you could try checking the ignition switch, crankshaft position sensor, and ECM for any visible problems or faults. You could also try checking the fuel pump and fuel pressure to ensure that fuel is being delivered to the engine. If these steps do not resolve the issue, it may be necessary to call a professional for further assistance.

Anti-theft system light on ? Security light ? What reset switch ? What make model an year vehicle ! All vehicles from 1996 on, the PCM/ECM - engine computer controls the fuel pump relay . If there isn't a crankshaft position sensor input to the PCM / ECM ,the PCM / ECM will not energize the fuel pump relay ! There are a few good videos on youtube on fuel pump electrical circuit testing . You need to test the circuit before replacing parts . Parts stores love guy's like you , your helping to make them rich !

you most likely have a fuel supply or pressure problem
1, a shorted injector, (this caused all the other injectors to stop working or work very inefficiently)
2, the cam sensor (the ECM uses this as a reference in timing the injectors in conjunction with the ICM)
3, the lack of fuel pressure to them (all the many things that can cause this condition)
4, a bad ignition control module ( the computer uses the signals from ICM for a reference to time the injectors as it monitors and changes the ignition timing)
5, a bad crankshaft position sensor ( the ICM is using this to set the ignition timing and to send the reference signal to the ECM)

crankshaft sensor or camshaft sensor which ever you have once it goes bad will not allow your fuel pump and ignition[spark] to work

The crankshaft position sensor identifies position of the crankshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM)

When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown.

The camshaft position sensor identifies position of the camshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM)

When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown

So many of them things could have been checked to see if they was bad or needed to have been replaced. I see this a lot when someone goes to guessing on things and they can end up having a LOT of money invested and still not running.
My first guess since you've replaced all of them things is either you may have a ground issue or a bad PCM.
I would start by checking that you are getting power to everything that you are supposed to be getting power.

Then, I would check that you are getting grounds to everything too! You must have both in order for it all to work! If you are getting both and if you know how to check for both at all places, then I would eliminate the PCM.

If it turns out to be the PCM, try checking eBay.
Hope this helps.

Hello first of all


well i am sorry a mechanic cant figure this out its really sad. ok so your problem is your either one of two things but most likely the first one i list.

1. camshaft postion sensor
2. crankshaft postion sensor

Now that being said it most likely the camshaft sensor the reason i say that is when a crankshaft postion sensor is bad the car has very hard starts and most of the time no start issues. When a camshaft postion sensor is bad the car cuts off whil driving and can be hard to start up again.

So that being said they are both pretty cheap parts i would go ahead and replace them both and i would bet my 5 years as ford mechanic that solves your issue.

The crank postion sensor is located behind the harmonic balancer pully or right beside it here is a picture from autozone.com and description.

The crankshaft position sensor identifies position of the crankshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM).

When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown.

Designed to meet or exceed OE specifications in form, fit and function.

And the camshaft sensor picture and info from autozone.com below.

The camshaft position sensor identifies position of the camshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM).

When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown.

Designed to meet or exceed OE specifications in form, fit and function.

The crankshaft postion sensor is 22.99 and the cam is 19.99 so 50.00 bucks and about hours time should have you up and running.

PS if this helps please 4 thumbs up it helps me continue to help on here thanks

Sound like you have a bad distributor pick up assembly, the distributor assembly pick up coil is what breaks down the voltage at ignition coil to give it spark, distributor will need to come out to replace pick up coil, mark your distributor rotor so when reinstalling you install at same position.

1996 Volkswagen Jetta 2.0L SFI 4cyl
The Camshaft Position Sensor is located under hood, center, upper engine area, driver side of engine block, mounted in distributor.

This sensor performs the same function as a crankshaft position sensor; providing a signal to the ECM regarding the position of the crankshaft.

Although the camshaft position sensor is an essential input for the ECM to determine ignition timing, information on testing the sensor is located in of this guide (autozone.com / free register).

Hope help you; remember rated this help. Good luck.

When you have no spark only it could be the ignition module. when you have no gas delivery only it could be a relay. However when both are missing. It is either your crankshaft sensor or the engine computer. Good luck. also see if the injectors are pulsing.
