Tacoma shuts off while driving. Please help.

My truck will randomly shut off with no warning at all. When it does stall everything electrical is still on (radio, lights etc.).its almost like i just turned the the truck off while driving. Also on occasion when this happens it wont just start back up. There is a no crank no start moment. Any advice on this would be greatly appreciated.

 

Have you plugged in a scan tool to check for any codes? And not just a basic code reader that Oreilly's or autozone uses. One that can see if there are not only current, but pending and history codes as well. That's where I'd start

 

Check engine light on? When the MAF sensor was going bad on my older Tacoma it would randomly stall like you describe, but it would start back up again.

 

No code no CEL

 

I would think fuel pump. Though you are saying you are not getting a crank at all when you try to restart? Loose battery negative or ground?

 

Loose battery cable? I had one on a truck that would occasionally rattle loose and the truck would die and not start until I tightened it back down. Everything electrical in the truck still functioned but it just wasn't a good enough connection to energize the starter.

 

New battery and i checked all the grounds. It doesnt happen when turning or hitting a bump from what i can tell. Its completely random. Ive checked every fuse and relay that would relate to it. I cant figure it out.

 

Could it be with the ignition module going bad?

 

It will somtimes shut off at idle in park.

 

Thats what i was thinking jacado but will that cause a stall while driving?

 

Check again for codes and pending codes.

 

Check crankshaft position sensor

 

Ive checked for codes everytime its happened. Last time was a couple months ago.

 

It shuts off when you're on the throttle or idling?

 

Does it have to cool down some before you can start it back up? Another sign it could be cps

 

If it was the crank shaft position sensor wouldnt it try to crank?

 

The last time this happened was a couple of months ago?

 

If there is a loose wire yes it will cause it short and stall out and then wouldn't restart if the short is still present. Once it cools down some short maybe corrected for the time being.

 

It has shut off both at idle and while on the gas.

 

How worn is your ignition key and housing. This could also pose a problem.
