Water code but no water....

[Ponce Inlet]

Truck has been at stealership now for 2 weeks.
Engine light came on after a hard acceleration. Next day, it wouldn't start. Turn over and over etc.
Wouldn't offer to start. Had it towed to dealer.

They find several codes and most will clear but down to two and keeps referring to checking an endless loop. According to dealer. Can't get the codes cleared. All circuits have been checked. Load tested as well.

The water in fuel light came on when it wouldn't start the next day. But there's no water in the fuel.
I'll admit I was scrubbing around the engine and cleaned with low water pressure.
I've only had this truck 2 months. Supposedly new injectors. 100k miles on truck.
Now they say it may be the PCM. I'm sure that will be cheap.

Any suggestions?
Thanks

Dealer now says it's the PCM; which they say is $6000?!?

You gotta really be careful pressure washing around ECM.

PMC should really be water tight have gotten my engine bay wet many times by goin threw water.

Then again i wouldn't really power wash the engine lol so who knows.. I would have someone else look at it tbh they are called the stealership for a reason!!
