Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
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?
Do you mean the whole truck was completely under water for 24 hours?
Do you need any further help?
I hope my advice has been of assistance to you.
You need to scan the vehicle for any codes set.
Can you do this?
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'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?
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.
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.
