I'm learning to drive a manual in a 2010 Frontier SE KC, with a 4.0 and a 6-speed. It has 61k miles. As expected, there's a learning curve to driving stick, and I occasionally find myself killing the engine at launch, sometimes more than once before getting the shift right.

One thing I've noticed is that a few times, the engine won't immediately restart. I've got the clutch down to the floor, the shifter is in neutral, and I'll turn the key. The truck will go into accessory but not crank. If I wait a while (10-30 seconds) and try again, it'll crank back up again. The AC is on, for what it's worth.

I checked the ECM with a Bluetooth OBD2 adapter and Torque Pro on an Android tablet; nothing was found except an evap problem. Is this normal behavior?

  • Thats not normal behavior - it may actually be linked to the evap issue Torque showed, can you post the code it gave? – motosubatsu Jun 7 '19 at 14:40
  • What do you mean by The truck will go into accessory but not crank ? – DavidSupportsMonica Jun 7 '19 at 14:42
  • @David the dash lights up, but the starter doesn't turn over to start the engine. If I wait 10-30 seconds, it'll crank and the engine will start. – nerdenator Jun 7 '19 at 14:46
  • What we all call the "ignition switch" is actually a mechanical lock operated by a key. With the right key, the lock turns and itself then operates the ignition switch, a multi-position electrical switch located just behind the mechanical lock. The truck's symptoms suggest either a) a fault in the electrical switch or its wiring, so that while the key is turned to "start," the electrical switch doesn't always rotate into the "start" position, or b) a mechanical fault between the mechanical lock and the electrical switch. – DavidSupportsMonica Jun 7 '19 at 14:53

    Does the non-start condition occur when the engine is turned off using the ignition switch, then re-started right away while still warm, and not re-started from cold? – DavidSupportsMonica Jun 7 '19 at 15:20
