Hi, I drive a 2008 Frontier SE 4x4 V6, manual transmission. If I hop in the truck, drive 10 minutes, and shut it off, it won't re-start for me. It turns over and the battery seems fine, but it won't fire up. This has happened a few times (including today). After about 30 minutes of sitting, it fires up. Based on the timing, I'm guessing the problem has something to do with temperature--like the truck is fine when cold or hot, but not when it's warm. I've taken it to two different mechanics (including a Nissan dealer) and they couldn't find anything wrong with the truck. Anyone else here ever had this problem and actually determined how to fix it? Thanks.

Seems like I’ve heard this problem before, can’t remember exactly what the problem was if they even found one. If I remember right..or at all..maybe the crankshaft position sensor. Might be somewhere to start reading up on.

I appreciate the info, MiniDuti. The Nissan mechanic actually mentioned the crankshaft/camshaft sensors when I had it there, but was hesitant to replace them since they weren't throwing any codes. But I think my next move is to get those replaced and see if that fixes the problem. Again, thanks.

It definitely could be the crankshaft position sensor. I have heard of them not throwing a code. There pretty cheap so you might just want to try that.

Cam sensors - maybe - but they typically throw a code from everything I have read.

When you say it won't start - I assume you just crank and crank and no fire?

Have you tried any diagnostics? Fuel / spark / etc.
