Lost power while driving, won’t start (1 Viewer)

[hskb]

Hi all, my 2000 LX lost power while driving. The power was flickering on an old battery. I replaced it with a new battery but still can’t start.
It gives a good crank but can’t start.

What are the possible issues?
Thanks for your help

If you have flashing security light (located next to the clock display in center console) while engine cranks, then try troubleshooting instructions in post #51. This is not a valid test if your security light doesn't flash while engine cranks.

Thank you so much Medtro,
Follow your guidance, i was able to identify the blown efi fuse. It's late, and i could not find my fuse box somewhere in the house so will have to do it tomorrow. It is at the shop at the moment. This morning i had to call tow at 6am since i was stuck on my way to fishing, and felt bad for the truck driver (don't worry, i tipped him well

So for now, can i just replace the 20A fuse, and get your kit to install it later? This is a huge safety issue as i was driving around 4am and this happened.
I'll email you for the kit.
thanks

Yes if it will start with new fuse. Keep in mind that it could stall again with new fuse.

still with the shop, first diagnostics: fuel pump ok, but NO spark. still trying to figure out.

 

[medtro]

You can save some money on diagnostics if you have flashing security light with key inserted and new fuse installed. I wouldn't spend money on any diagnostics until there is no flashing security light with key inserted. Have you or your shop tried the procedure linked in post #2?

^^^^^ @hskb highly advise you listen to this guy.

i shop called again: new fuse inserted, and the key still persists.

i asked him to try the jumper, but he advise against it.

he can't scan it since there is NO communication.
he is doing the computer reset now.

Bingo !
The jumper method from medtro's writeup works like a champ !!! Thank you so much. Hopefully the kit i ordered from you earlier this morning coming soon.

Thanks BullElk and medtro for encouraging me to do it. At first, i didn't want to do it in respect for the shop since I've parked my LX in his shop for over 24 hours, but thinking of either rebuilding the computer, or buying a new one made me decide to do it

The shop didn't want any compensation, but i paid them anyway for their time.

The truck is grounded for now until the kit comes
Again, i would like to thank Medtro for his work, and thanks this forum and its members for all the help.

Is this an issue with certain years or with all 100 series?

Not sure but I have personally had the immobilizer issue on both of my 2000s but not on the '99, '04 or '06 and all have over 300k miles. Perhaps Toyota corrected the issue after around 2000.

Mostly 1998-2002. 2003+ models have a different fuse box.

Great (sarcasm), now another thing to learn, be prepared for that can take a crap when on the long haul far from home (let's face it, that's the ONLY Time anything ever craps out on any of us, right?)
