Hey guys It's not a Hilux or Pickup but it is a Toyota and I figured this would be the best place to check.My buddy got a 95 T100 for free that went down a couple of years ago due to a "fuel issue". I went over yesterday to check it out and went through the usual checklist and found the EFI fuse blown.Popped in a new one and it pops right away,key off nothing on just battery.I pulled all unecisary fuses to try and eliminate a ground some where.I also unplugged the fuel pump and same thing still popping.Does any body have a wiring diagram PDF for this truck.I pretty much narrowed it down to a harness with 6 wires but don't know where they go.If any body has some insight or that PDF it would really help.Thanks guys.

 

My bud has a t100 and it did a similar thing I strolled Thru sme things while sourcing his problem it ended up being the Efi relay

There's a lot of sensors on that fuse Maf o2 fuel p and some more this is not a t100 but its a start in the direction
Some t100 guys say o2 harness gets burnt buy exhaust
Check this

yeah I checked the o2 sensors for the same reason but they "looked good"there are 2.

 

I checked the relay and it also looked ok but I'll go ahead and change that.

 

What's the fuse do when the ecu is unplugged and the batt hooked and key turned to battery
