EMERGENCY HELP!!! Flooded interior...

Chris, I agree with 4runnercaged, if you need help I,m close, just need a electrical diagram and we can check it out before you plug in the new ECU.

 

Got the new ECU. I'll get Robert to come over and help me out.

 

Sorry about the issue - i give you credit for going into that water hole big balls you have, or perhaps mine are small.

 

Cool, Call me when your ready..

 

I may have a wiring diagram if you need it.

 

you better!!

 

Bad news...

Started by checking for grounds, nothing unusual. Plugged new ECU in, nothing unusual. Turned key on, got normal lights plus CEL. Tried using OBDII sensor but got a "link error". Tried starting engine, but had no change in sound or feel than from old ECU.

Gonna call my insurance company tomorrow and see if they will help pay for repairs when I take it to the dealership...

 

Truthfully I don't understand what you mean by "no change in sound or feel". The truck either cranks or doesn't crank

 

The starter turns the motor but it's not sparking.

 

link error.? You're positive its spark and not fuel?

 

No, not positive. Not really positive about anything at this point.

 

id honestly have to say at this point, at least try checking the fuel pump. when my truck died on me, it would just keep trying to turn over, but it wouldnt start up since the fuel pump was dead. I had replaced the starter and battery at the same time and it still just tried to start, but didnt. its at least worth a shot

 

You could have called a group meet and let everyone have a crack at it.

 

If you were closer I would say put her on a trailer and tow here here. I would have it figured out in an hour or so. Those problems are my specialty.

 

4 hours is close.....ish

 

so you are getting a communication error between the obdii scanner & ECM? do you have a known good ECM you can try. that ebay ECM may be in the same condition as your sub'd piece.

what are you doing to check for spark? check for fuel?

 

What do you mean you don't know if it has spark? Do you know how to check if it has spark?

 

It's worth a shot

Where are you located?

Haven't checked spark since it was in the woods. Can try checkin again. Haven't checked fuel. Don't know how, yet.

 

Ah doesn't sit in a metal tray in the truck?

 

Here is what happens when electronic parts get wet while they are powered. The water is to some extent is conductive it forms a pathway to other parts on the board all solid state devices do not like reverse current the smaller they are the more likely they are to be damaged. This includes all ecm modules that had water in them. If you have insurance and water was up to the dash it is an automatic total.
