Cranks but will not start

Hi and thanks for using 2CarPros.com.

If you have spark and fuel, it should run. That tells me either timing is incorrect or there is no injector pulse triggering the fuel injectors. Will the engine start for a couple seconds if you use starting fluid?

Lets do some testing first. Let me know if it starts with starting fluid. If it does, I need you to do the following checks:

If they are working, I need you to check engine compression:

These engines are known as interference engines. If the belt broke, there is a good chance valve damage was done to the cylinder head. That is why I am questioning compression.

I attached a picture of the timing belt and marks. Confirm it was installed correctly.

Let me know what you find or if you have questions. I will watch for your reply.

Take care,
Joe

Hi again,

If you have no compression, either you have bent valves or the timing is way off. Did the timing belt break or are you replacing it as a preventative maintenance item? If it broke, I have a feeling you bent valves and that is why there is no compression. Let me know if there is zero compression. And no, you should not be able to turn it easily by hand. If you are certain the timing is correct and again, no compression, you need to remove the cylinder head and inspect the valves. Let me know if you need directions, have questions or anything. I check my replies no less than once a day.

Let me know,
Joe

Lets do a compression test in all cylinders to see if the engine is okay.

Please run down this guide and report back.

I would fix the intake camshaft timing first. Here is a diagram of how the marks should be:

Yes, that will do it. Let us know what happens and please upload pictures or videos of the problem?
