Default 2007 Navigator Cranking but not starting. Video Included

I'm having some problems with my 07 Navigator. The engine cranks but it never turns over. The spark plugs and caps are new, the fuel pump is a year old, the relays and fuses are good. Any idea?

Hi

So it turns over, but won't fire.

Did it just suddenly not start after running great, or has it been giving you some signs it's not running right? No check engine light prior to not starting?

Many many things can cause a no start. You need to check for spark at the coils, check for fuel at the fuel rail.

A scanner would be helpful.

It just cranks, never turns over and fires.

It was sudden. It just wouldnt start one day had to get it towed home.

A check engine light or any other warning light has ever came on.

Where could I grab a scanner at?

Thank you for your reply!!

You can check some basics before you spend any money.

Check for spark at the coils. Pull the coil off the plug and with it plugged into the harness, and with a spark plug inserted and the shell grounded, have somebody crank it over while you watch the plug for spark.

Turn off your radio and then turn the key to the run position, don't crank it. You should hear the fuel pump hum/buzz for a few seconds if you are getting power to it and it operates. No noise means no fuel is getting to the engine.

From here you can search for a scanner. You need not not only read codes, but you need to be able to read live data. Expect to pay $50-up

Did you ever determine what the issue was? I am having the same issue with my 07 Navigator. Fuel pump is working, getting spark, etc.
