Why is my 08 shutting down?

I have a 08 Taco PreRunner SR5 double cab with 61k miles. Two weeks ago it shut down while driving the interstate on the way home. All electrical remained on and working (power steering, brakes, windows, A/C, stereo, etc), but the engine shut down. I shifted to neutral and cranked it right up. A few hundred yards later the engine shut off again. Again to N and re-cranked it. Delivered it to local Toyota dealer. No codes were thrown. They got it to repeat, but after 3 days couldn't find problem. Then I picked it up at no charge and it ran great without issue for a week. Today on the way home from work, it shut down again on the interstate. After restarting twice, the third time it wouldn't start again so I pulled off to the median. With key in ignition, all electrical worked except gauges. Still wouldn't start. After a few minutes, it cranked right up. Then as I tried to drive to dealer again, it shut down again and ultimately had to be towed. So, elec windows work, stereo works, A/C works, lights work, etc, but gauges don't and no electricity is going to ignition to start. Any ideas? Its at the dealer service bay awaiting Monday now. Help please !!! Thanks!

 

If they dont find anything take it to another dealer.

 

Check for a loose main fuse maybe? Theres two ignition circuits in the truck. Look under the hood for the larger fuses, I do believe they are screwed in.

Oh and your power steering and brakes only worked because the transmission was still in drive, thus driving the engine enough to keep the power steering and vaccuum system up... BE CAREFUL! If you slip it in neutral then it won't drive the accessories anymore and you will have a hard time stopping.

 

Well idk if this is why, but when i installed my oil catch can there was an open air leak which caused the truck to idle at really really low RPM's and i was driving and the engine died. But all electrical was working perfectly, so it might be that. No expert, just thought i would throw in my experience. Hope you find out what's wrong!

EDIT: O and it didnt throw any codes either

 

Honestly sounds like your ECU has gone the way of old yeller though.... All the other items work because they are on different circuits.

 

Could be fuel related. How low was your tank when it shut down? Fuel pump could be going bad or even clogged.

 

My old Honda Accord did just as you described: shut down with all electronics okay. Towed to dealer: replaced fuel pump with NO issues after that. Bad fuel pump would not throw any codes since it was fuel related.

 

check alternator, and check battery connections! might have a loose ground. get some battery terminal cleaner, unplug your battery and get some steel wool, spray said cleaner on terminals and scrub them with the steel wool and see how that fares. you could also have a bad terminal wire coming from the truck. id start at the battery since it is the easiest!

 

Check your fuel pump.

 

Please keep us updated as to your results!

 

symptoms sound like a loose connection or possible fuel pump/fuel filter issue.

Fuel, Spark, and Air still holds true, even for modern vehicles.

 

sounds like you could had a ground loose somewhere or the fuel pump ... in any case http://www.urdusa.com/Fuel-Upgrades...mp-and-Kit-for-2005+-Tacoma/product_info.html that is the fuel pump you want

 

I had two different Ford escorts that died like that. Ford replaced a sensor under the hood but I don’t know the name of it.
