Computer plug in won't work

[lbyler86]

Tried plugging my tuner in the other day and wouldn't work. Figure it's a blown fuse but I don't know which one powers it. Help me out!

I had that problem on a truck and it was the accessory/cig lighter fuse. Can't remember if was on a second gen or not, but you might check that first.

Should be fuse 12, 10A. This is from a 2001 book and I know 2002 is the same. What year is your truck?

my truck is a 99

Give it a try. I'd be willing to bet it is the same but not certain. Just take a test light and touch all the fuses. You can find it pretty quick.

make sure when you go to plug it in the pins are not pushing out of the connector, very common. also so is the ground.

Most overlooked item everytime while troubleshooting electrical issues.

Also do a continuity test on the fuse if uncertain. Fuses can and do blow in weird places where the eye test says it is good to go.

Make sure the pins aren't splayed at the dlc
