Hi there,

You say "got the water off the pistons", has the engine swallowed water?

If so, it probably has some bent conrods.

Is it making any odd noises?

It was under water for 24 hours but I didn't try to start it until I drained all the fluid and refilled with good oil
Expert:  Gary replied 3 months ago.

Do you mean the whole truck was completely under water for 24 hours?

Expert:  Gary replied 3 months ago.

Hi again,

Do you need any further help?

I hope my advice has been of assistance to you.

Kind regards

It starts and dies
Expert:  Gary replied 3 months ago.

You need to scan the vehicle for any codes set.

Can you do this?

It isn't coding anything
Expert:  Gary replied 3 months ago.

How much under water was the truck?

Above the chassis rails?

Did water enter the cabin?

Have you taken a fuel sample from the fuel rail?

I had a suckshion on my gas tank
Expert:  Gary replied 3 months ago.

I'm sorry to hear about your house as well.

I've heard on the news of all the flooding, hope you will be ok after this.

Strange it has no codes.

Normally with something like this there would be modules not communicating.

What scan tool do you have, and can it communicate with the ECM and the BCM?

Hi Wesley,

I don't think we will get anywhere with this problem remotely, so it would be wise for you to have the vehicle towed to your nearest workshop for further diagnosis.

Kind regards

Thanks for your help
Expert:  Gary replied 3 months ago.

I wish it was a better easier, but a flooded vehicle is very hard to diagnose remotely.

I hope you can get it fixed economically.

All the best to you and your family Wesley.

Kind regards

Gary
