Replaced water pump, timing belt, and camshaft sensor. Timing is correct. Wants to start but will not. Has spark, has fuel up to injectors, but plugs are not getting fuel. Fuel injectors are clean.

Hi and thanks for using 2CarPros.com.

The first thing we need to determine is if the injectors are getting power to work. Here is a link that discusses how to check them:

If you find they are getting power, then we have a different issue. If there is no power, I recommend checking to see if there is a signal from the cam sensor. You will need a live data scanner to do so. If you even have a basic scanner, determine if there are any codes set which would indicate cam position sensor issues.

If you find there is no signal from the sensor, check for disconnected wiring, damaged connector. The cam sensor sends a signal to the power control module which is then used to trigger the injectors in the proper sequence. If it is not working, there will be no injector pulse to fire the injectors regardless if there is gas to them. See if it starts using starting fluid. If it does, at least you can be certain the timing is correct.

I have attached two pictures of cam sensors. The first one is for the DOHC engine and the second is the SOHC engine. I am not sure which you have. Anyway, I thought it may help locate the component for you.

I hope this helps. Let me know what you find or if you have other questions.

Take care,
Joe
