'98 4 runner won't start


Asked by Feb 17, 2016 at 11:17 PM about the 1998 Toyota 4Runner 4 Dr SR5 4WD SUV

Question type: Maintenance & Repair

I took the computer out of the truck to test
on another truck and when I put it back in
the truck had no power to the dashboard or
ignition. The truck was totally fine before I
took the computer out.  We're thinking it has
something to do with the alarm system.  
Help please!

1 Answer


you may have shorted something out when you installed it in the other truck - swapping these out from vehicle to vehicle is not a good idea - PCM are usually programmed to the vehicle it is installed in. I'd have a professional take a look
