Replaced E4OD MLPS, and accidently touched one of the wires to ground while re-pinning. Starter bumped, and got a spark. It started in park and ran great for about 5 min., started shifting hard again. Parked it, went back and now it won't start in park, and every thing on the grey/red circuit no longer works. Truck runs, but not well. Did I fry the ECM? All the fusable links look ok.

 

????????????
please clarify problem

 

X2 that's like working under your truck with no jackstands could be dangerous

 

X3

 

While it's very true that he should've had the battery diconnected, I'm pretty sure he knows that based on his post. Noone has made an effort to help him with his problem. People come to this forum to seek help, not to get shot down for making a stupid mistake. I can speak for myself that I make stupid mistakes all the time. Why just the other day I let my truck run out of gas because the tanks were cross-filling. I sat there scratching my head and it took me about an hour of diagnosis to figure out that my truck had somehow disposed of 18 gallons of gas in 130 miles due to it all moving to my non-functioning front gas tank. So please, in the future, help new people...

To the original poster, what made you repin the ECU and did the truck run correctly before you did this work?

 

I think what we have here...is a failure...to communicate. Repining the ECU & replacement of the MPLS is not only not on the same page, it shouldn't even be in the same chapter!

OP, please restate the situation more clearly if possible & specifically define "your" repin. Then we can "Get da fixin party started"! I got some ideas, in the meantime leave the ECU where it is, as it's probably just fine. You're also gonna have to cough up the year & engine of your truck.

 

I had an ecm that was in fail safe mode for a goo year before i replaced it i think you might have fired something else there are allot of fuses and other things that are going to fail before the ecm will. grounding it should not be an issue. but if it thew sparks you might have destroyed it. i replaced mine and touched it to a grounded piece of metal and nothing happened. but my battery was detached. see if you can pull codes from it if the check engine light stays solid its in fail safe mode.

 

Perhaps the few of us who replied at first didn't know how to help him. Noone shot him down, one asked why it was disconnected and two more (myself included) agreed with the question. So please, in the future, don't go on a mini rant and just answer the op's question.

 

I know responses like those three would've kept me from asking anything else from you guys.. and the first response was more or less a "you idiot, why was the battery connected while you were doing electrical work" The second response was an echo of this, and the third was you, maybe you didn't read the first response the same way I did. Apologies if I offended you sir.

Still nothing from the OP..

 

Wouldn't have stopped me. If I came for help with a problem then why would I just stop? Obviously the site doesn't consist of 3 people that wonder why I didn't do this or that. If that's how you interpreted what the first poster said then you're putting other meanings into something that was pretty clearly asked. Why wasn't it disconnected and what did he mean by re-pinning. Maybe he figured it out or has someone working on it. Happens all the time here I've seen. Post a question and never come back.
