We have replaced the alternator, brand new battery, spark plugs, fuel pump is working and good, and cleaned and added new fuel injectors. But the car keeps cranking and wont start. What could it possibly be? The timing belt is still good and the fuses are all brand new. My starter is working fine because the car is cranking. Why isn't it staying running?

Hello,

This could a problem with your Camshaft Position Sensor [CMP]. If the CMP is not sending a signal to the Engine Control Unit [ECU] your vehicle will not start. Here is a link explaining how to change a camshaft sensor below:

In the diagrams down below I have included the location of the CMP on your vehicle for you. Please go through these guides and get back to us with how everything turns out.

Thanks,

Hi, just wanted to jump in here. I would recommend you check the coils for spark. If you have spark then check fuel pressure. If you have good fuel pressure then check for fuel injector for a pulse. If you have no pulse then most likely an immobolizer issue. Here is a link on no start. Let us know if you have good spark, fuel pressure, and injector pulse.

If you have no injector pulse I would suspect an immobolizer issue. Try a different key. Let us know on your test results to proceed.
