Cranks but will not start

Good afternoon,

Are there any codes stored in the PCM?

Have you tested for fuel pressure? You can try to spray some starting fluid into the air filter and see if it starts and stalls. That will tell us if it is fuel related.

Did you check for spark?

Lastly, did you test for compression?

You need fuel, spark and compression for this to run.

No codes. Have checked all that you asked. It has me stumped Tried starting fluid too it did nothing. Did not even try to start it just kept cranking.

Everything works fine but it just will not start.

Did you verify spark at the spark plugs?

What was the compression?

Roy

My friend is a mechanic and he did both and said the compression was good.

He is thinking it may have jumped time, but no indication it has.

He is a mechanic? If the compression is good, then it is not the timing. If the timing was an issue compression would be off.

He missed something here. I would look for someone else to help you with your checks.

Roy

Is there anything else that you could think it could be? I am scratching my head here.

The guy I had check compression is only mechanic I know.

You need to start with basics.

1. Spark

2. Fuel pressure. Need exact reading not it is okay.

3. Compression. Need exact numbers.

If you cannot do it yourself, I would consider a mobile tech to at least do this portion of the testing.

Roy

He had exact reading I just did not write it down.

Okay, I want to help but remember I am here and not there and I need exact information.

Keep me updated.

Roy

No problem. Thank you. I will do that.

You are welcome.

Roy

Just an update here. Timing chain gear broke.

Oh, sorry to hear that.

Most likely you have damaged valves from that issue. Then I would like to know what caused it to break. They do not just break for no reason.

I would be ready to consider changing the engine at this point.

Roy

Picture.

Think it is called the key way.

Yes, that is correct.
