Diagnosing my possessed Tundra

Aloha from Maui, HI.

Just recently broke down due to a electrical issue in a remote area. Hit some sort of pot hole and it rattled something and the truck completely shut off. Immediately after shutting off, while I was in 2wd, the 4lo, 4hi, VSC and traction lights all appeared and was flashing. (No CEL).

Needless to say, I had to get a tow back to my home. After a visual inspection of the engine bay, fuse blocks, I found the EFI no1 Fuse was blown, So i replaced that and tried to start the truck.

Before I could even turn the key to Ignition, it started in the Acc position.
The starter engaged and stayed on even after the truck had a successful ignition. After turning the key to OFF, the starter was still engaging thus resulting in pulling the battery terminals off.

Since then I have check the starter relay to see if it was functioning properly. It is. So after thinking about it, I think I have narrowed it down to a malfunctioning solenoid/starter or the key ignition relay or switch.

Has anyone had this kind of issue and how has it been rectified?
Much Mahalos in advance for any information

 

Vehicle specs:
2007 Crew max 4.7L
56k
No engine upgrades
Remote start: unknown if previous owner had Viper alarm or Remote start

Repairs/Maintence with in 2 years:
~Replaced Alternator within 1 year, less then 3k miles(Avg 6-7k/year)
~New battery within 1 year, less then 3k miles(Avg 6-7k/year)

 

Well after I replaced the EFI fuse, all the dash lights went away. Sorry I forgot to mention that but Ill check that out tomorrow morning.

 

Ok so i got it back from the shop and the NSS(Neutral saftey switch) was at fault. I started up the truck, no problem. Ideling around 500rpm. Put it in reverse, no problem. Shifted into drive and it took about 4 seconds to engage. Though that was odd, so i drove it back into the driveway and it died. The EFI fuse blew again but this time the A/T Temp light was on. I have no idea what is going on. I live in Hawaii so its mostly in the 80's all year round.

 

Maybe your Truck has a touch of Island Fever.........

 

Welcome from Kansas. I will be in Maui by end of this month! Sorry I am no help with the problem.

 

Welcome from Colorado. Did you take any rocks from Volcanoes National Park? I believe if you do back luck rains down on you from Pele. Probably not much help, but all I got.

 

Nice day for an exorcism.....

 

I think it's supposed to be little island idols, that's how bad luck follows you.

 

You live on Maui, AND drive a tundra........you're living the dream.
Sorry I can't be any help, hope you get it all worked out, electrical issues are so frustrating.

 

Haha no, I know better then that. Lived maui for long time

 

Have you been to HI before? Lifted truck scene is huge out here.





Ill keep everyone updated.

 

I am betting the remote start has something to do with this. I know when I had my remote started installed it was routed through the same wires as the EFI. Perhaps something is shorted and causing excessive amperage to the EFI fuse, try disconnecting the remote start and replacing the EFI relay. I had a fuel pump relay go bad on my 4runner once and had similar issues to what you are describing.

Also I did not see your post referenced in the Toyota Mechanic thread (referenced above)!

 

I can't guess what the issue might be OP, but that is a dam good looking Tundra!
I am sure you will get it resolved. Lots of knowledge on here.

 

Well finally after 2 shops and 3 months later, the tundra came back. Was the ecm. Toyota replaced for free seeing as it was still under a extended manufacturer warrenty. Whoopie

 

Actually a short of any kind, with enough juice (like crossing positive with negative ports) will short out the ECM. Luckily, it was still under warrantee. Cool beans.

 

Did they remove the remote start? I had an accident in my Crosstour and the exam went, they removed the remote start at the same time.

 

****ECM stupid spellcheck!

 

No idea what went wrong with the ECM. Took the truck on the road to hana back side. No problems except puncturing a tire.. lol. my fault, dam lava rock.

Sucks, now I gotta buy a new nitto trail grappler.. lol Shops here are quoting me at 600-700$ for 1. FML


So I took the paint of my stocks which the previous owner painted and it doesn't look half bad. Might be considering getting rid of my Fuel Mavricks and nittos for some Chrome 20x12's.
