Low Power after hitting a bump

[Gzes]

Well in a 2000 explored I had 2 keys one that would just unlock it but If I stuck it in the ignition I couldn't turn it on cause there was no chip but if I got the one with a chip then it would start up and drive and whatever. You should put in a new ground wire tho

Scratch they Key Idea- I took both keys on a little trip tonight... Both were OK.

Is it possible since I removed the ground from the hood to firewall that fixed it? Since it was loose could it have caused a problem. It doesn’t make sense to me I'm just happy no power loss right now.

Well if it's working now then I would say don't try to fix it if is already fixd or you might break it again

I will post results back in a few days to let you know if it all good

Think I Isolated the problem... (Yes Im still at it)

First- I replaced the useless ground on the hood and visually checked all front grounds. (All Good)

The Short is happening much, much less frequently

I found a stretch h of road that would trigger the short. And I drove it a few times tonight. I found that by pushing in on the key (Towards the column) I wouldn’t short out.

If I let go of the key It would short out.

I've already replaced the Ignition Switch, so could it be the key mechanism? If I jiggle the key I cannot duplicate it, only over rough bumps..

Bump for more ideas. It is not near as bad as before but still happens over rough stretches of roads.

after 2 weeks its back again... It is much worse now. It is causing havoc on the engine and tranny along with the gauge and door locks.

Im wondering if it could be the PCM... Any help is appreciated.

Bingo---Took it to local dealer today and we were talking about it and both agreed it to be the BCM... but he wanted to have someone diagnose it to be sure... I get a call back later saying the BCM is fine it is just one of the grounds on the back of the block... (I thought I checked all those) Anyways that’s the good news and truck is ready except the say i need to replace the pitman arm, Idler arm, and outer tie rod... (At least its not electrical)
