      Thanks for the comment! I'm glad the video helped! I kinda thought with the way that harness came out of the fuse box, that this may not be the only one.

    Hi! I have a 91 Toyota 4Runner and I have an issue with a rattling within the automatic shift (from P to R to D) and was wondering if you have any advice. I have a video of it happening. Thank you so much for your time! 😊

      Key was off. The black lead from the tester was on the negative or ground. When the tester beeps it's telling me there was a short to ground.

      @@J20Jeepster mine is blowing only when you attempt the start but not in the on position. Does this mean the short is likely in the fuel injector harness under the intake manifold where mice love to nest? It only blows when the car is trying to start.

    Hello everyone as you guessed I have a Toyota 4runner and having problems.. I've dealt with them myself in the past but can't pass this one. Hopefully someone can help. So my problem is new battery cables are fine, but when I put the key in the ignition no power what so ever, no click, no dinging noise and if I turn the key to on can't even move my gears? It was parked for a while but we jumped start it the 1x it turned on fine and stayed on, few days pass jumped started again kept dying then finally the problem with no power anything what so ever. Please someone help thank you

      Sounds like a main ground issue. Have you checked all your grounds / cleaned contact points to chassis?

      Replaced the relay and no change. I'm going to look at the cables you pulled but my EFI only blows during start not the on position and my 4runner sat for over a decade so I suspect the harness for the fuel injectors under the intake manifold are chewed by mice. What are your thoughts? Thanks for your help. 93 4rumner 3.0 4x4

      @@lance7413 You have a short to ground somewhere. This is all that's on that fuse: EFI Main Relay, Circuit Opening Relay, Data Link Connector 1, Engine Control Module (Engine and Electronically Controlled Transmission ECU (A/T), Engine ECU (M/T)), Fuel Pump, Heated Oxygen Sensor (Oxygen Sensor) Main, Heated Oxygen Sensor (Oxygen Sensor) Sub, Volume Air Flow (Air Flow Meter), VSV (for PAIR), VSV (for EGR), VSV (for FPU)
      I would check wiring to each of these systems. Hope you find it!

      @@J20Jeepster i.may have gotten lucky. I have some hacked wires to the injectors running down the driver's side of the harness. They aren't wrapped and it appears someone did a quick repair on 2 of the wires. The electric tape appears to be burned or melted. I'm going to cut that tape off and look at the connections. I haven't pulled the intake plenum yet so I'm psyched that I found the hack before I pulled it. This might very well be my short.
