2006 Nissan frontier won't start it sounds like it is running out of gas but all the electric comes on and barely starts for about a good 3 mins.

hi i had same problem a few days ago brought to the dealership and turns out there is a clutch stop sensor that if it is not making contact will not allow you to start using the key part cost about $25 with labor it was $113 to be fixed at dealership seems it only last about 30-35k miles before breaking if yours is manual that could be your problem hope this helps

What is the flip warning light? Does the engine crank over?

Your starter solenoid is probably bad if the battery is good. Not sure if you can get just the solenoid or you have to buy the whole starte. Also check to make sure the cables are tight not only on the battery but the starter as well

when you check for spark check all cylinders u can use a regular spark plug and wire ground the plug end set the gap a little higher than veh calls for then yuoll know if it can have enogh to run all cylinders if you find only 2-3 firing thats still considerd no spark. hope this helps THUNDERBOLTZ
