need help and fast my 90 4 runner has a bad electrical problem / my engine will not shut down unless i pull the ecm breaker .it starts fine and runs great but when its wet out it keeps running and my power door locks wont stay locked if the door is open they will stay locked if the door is closed .also the idiot lites on the dash stay on is there a specific place to look for this problem. battery is new and charging is perfect

 

when it gets wet? start looking for exposed wires or relays.

 

thanx 4 the reply and i fixed the problem .Had to replace the whole fuse panel on the left side water and moisture had corroded the breakers and thanx 4 the help

 

Kind of puts a whole new spin on "these trucks never die"

 

you got that rite lol

 

hey man.. i have a question for you. i have a 90 4runner too. sr5 v6. im having trouble with electrical too. (i think) once in a while, my truck just, wont start. it turns over just fine, has plenty of spark and power, just keeps turning over. i leave it alone for a bit, and it will start and run just fine for weeks straight... frickin weird and starting to get on my nerves... i think its some sort of exsposed wires or relay, something but cant find it. sound familiar??

 

my problem was my fuse panel was getting wet there was a hole in the floor i didnt know about and a crack between the inner and outer fender from what i have read try and cover every open wire or exposed wire with tape or shrink tube and check your fuses and all relays for corosion if there is some on the tabs replace them or wire wheel the crap off hope this helps u man

 

I had a T100 one time that would just die... Almost killed me a time or two, too...

Turns out a connection had come loose behind one of those fuses under the hood. I had two life long mechanic friends look at it and they gave it right back.. no probs... Gave it to Toyota fearing the worst, a $1,000 repair bill... It was $60 $75 IIRC...

Look and see if the check engine light comes on once you turn it to the on (but not start) position. If it does not, pretty sure your ignition or ECU is not hot.

Mine would not start unless that light came on. The sucky part was I didn't notice that before and the truck got fixed a few days later.
