Hi,

I have a 1985 4runner that strangley stopped running. 22re w/automatic 186k. i drove to work and back one day and two days later it would not start, it turns over and that is it.

so far, tested voltage at fuel pump and its only getting .3 volts (weird). ran a jumper wire to it off the battery. pump worked just fine.

motor is not getting spark. tested two diff cylinders, and not getting power to or out of coil. ran hot wire to coil pack and fuel pump. engine started but ran very rough.

engine would not rev past 2-3k before sputtering out as if its flooding. check engine light finally came on but assuming its from us bypassing the computer controls but i dont know for sure as i dont how pull a code out of her.

all the fuses appear to be good, engine ran well until this point...thank you for any help/suggestions.

Thanks bro,

I will take a look at that fuse. Im thinking it could also be the Circuit Opening Relay.

Check the Ignition and EFI fuses, my 86 4Runner did the same thing one day, the fuses were good but they had a thin layer or corrosion on them and lost power. I replaced the fuses and all was good and it started right up.

ok ok myyota. i've checked all the fuses too. was this corrosion visible? i already switched out the efi fuse that sucker was $30 bucks. thank you

Blue Steel

that ignition fuse is under the hood right? or under my steering wheel?

myyota

The efi and ignition fuse are behind the driver side kick panel inside the truck. I have no idea what fuse you replaced that was 30.00 dollars.

in the newer 4runners the EFI fuse was under the hood on the left side. at least on my buddys 95

So you had a bad AFM ?.

indeed i had screwed around with it about 2 weeks ago and accidently knocked those wires around. and sure enough that was it. on that link up there what his problem was WAS LITERALLY what happened with me =D
