Pathfinder 2003

The Engine Cranks but does not fire. I have checked the fuses and on a suggestion used a second ignition key. I need help

There could be several causes here.

Check to see if you are getting spark to the plugs. Remove one of the plugs and reconnect the plug wire and then ground the plug and make sure you’re getting a good blue spark jumping the plug gap.

If getting a good spark…then make sure you’re getting gas??? Have you tried just starting fluid???

Make sure you aren’t holding the plug or wire while checking for spark unless you’re into 50,000 non-lethal volts up your arm.
