I have like electrical issues read push button doesn't work. I have all time-low battery the warning triangle and my two analyzers say no code in the system. And the radio sometimes works and sometimes not. If possible, please help me by showing me which one is cylinder one on these six inline cylinders 2.9L turbo and how can check compression test the car was cranking and running well before.

Hi,

Is the starter motor engaging? Also, have you checked the battery to make sure it is good? If you haven't, here is a quick and easy way to load test it at home.

If that is unsuccessful, remove the battery and have it load-tested at a parts store. Most will do it free of charge.

If the starter does engage and turn the engine, in most cases there is either a fuel-related issue or an ignition issue. If it does turn the engine, see if it starts for a couple of seconds using starting fluid. If it does and then stalls, we know it is a fuel-related issue. If there is no change, I need you to check for an ignition spark at the spark plugs.

Here is a link that explains how that is done:

As far as your questions about engine compression, here is a link that explains how it's done:

Based on your symptoms, I'm not sure why you want to check compression. Is there something that happens that leads you to question it?

Also, I attached a pic below providing both the firing order and cylinder 1 location.

Let me know if this helps or if you have other questions.

Take care,

Joe
