Hello. My name is ***** ***** I will be assisting you today. This is very bad. The first thing to do, is let the vehicle completely dry. With him pressure washing the motor while it was running, he has more than likely shorted some things out, and possibly the PCM. A good sign is that the vehicle still turns over. Do you know if he sprayed the spark plugs and wire/coils area?

Customer: replied 5 months ago.
Yea i believe he did
Expert:  Todd M replied 5 months ago.

I understand. Once the motor complete dries, he should first check all the fuses and replace any blown ones. If none of the fuses are blown, then proceed to check to be sure that no water has gotten into the cylinders. This would prevent the cylinders from firing.

Expert:  Todd M replied 5 months ago.

After this, if the vehicle doesn't start, then you would need to check for fire and fuel as usual, but if you aren't getting fire or fuel, then I would check the PCM.

Expert:  Todd M replied 5 months ago.

I am leaning towards that if you let the vehicle dry and check the fuses, the vehicle will start. There is a possibility of electrical damage, though. Just so that you are aware.

Yeah this is dumbass here and i sprayed everything.. I tried starting it for about 6 hrs. If fired up 3 times but only ran for a few seconds. So what is the pcm?
Customer: replied 5 months ago.
I pulled each coil pack and they were all dry
Expert:  Todd M replied 5 months ago.

The PCM(powertrain control module) is the computer for the vehicle, which controls the fuel and ignition.

Expert:  Todd M replied 5 months ago.

If you started for a second then shut off, means that the vehicle is capable of running, it's just dying out. Could be because of a sensor or the PCM. Do you have a scanner to try and scan for codes?

Customer: replied 5 months ago.
I was spraying in that direction of the pcm when the engine turned off
Customer: replied 5 months ago.
No scanner
Expert:  Todd M replied 5 months ago.

I understand. What has likely happened, is the water has shorted the PCM out. If this is the case, then it will have to be replaced. Before we jump to conclusions, I would at least give the vehicle time to dry out.

Customer: replied 5 months ago.
How long do you suspect this should take
Expert:  Todd M replied 5 months ago.

Not a hundred percent sure, but I would at least wait 24 hours.

Expert:  Todd M replied 5 months ago.

You may even want to disconnect the PCM and the battery.

Expert:  Todd M replied 5 months ago.

Just to be on the safe side.

Customer: replied 5 months ago.
While it's drying
Expert:  Todd M replied 5 months ago.

Yes.

Customer: replied 5 months ago.
Our for how long
Expert:  Todd M replied 5 months ago.

?

Expert:  Todd M replied 5 months ago.

Yes, you should leave it disconnected while drying.

Expert:  Todd M replied 5 months ago.

If you have anymore question on this issue, don't hesitate to ask. Also, please don't forget to rate the service. Thanks again.

I replaced the pcm still doesn't stay on
Expert:  Todd M replied 5 months ago.

You will need to have the circuits check to see where the issue is. The issue is likely going to be apart of the ignition system. You can try monitoring the spark and fuel input during the time that you are starting the vehicle. You need to know which one(if not both) is cutting out.

Expert:  Todd M replied 5 months ago.

This type of monitoring can be done with a capable scan tool or an oscilloscope.

Where is the gas line located
Expert:  Reggie Whiddon replied 5 months ago.

Hello are you still needing help i would like to help you. The first thing that i would like you to do. Is disconnect both battery cables and rub them together as to make a good connection and then take something like vise grips and clamp them to each other and leave them like that for 10 15 minutes. Then disconnect and hook up your positive first and then the negative. Do i understand that you replaced the PCM? Did you get that pre programmed with vin or did you or someone else program it? Chrysler has fairly good sealing technology on there connectors, I pressure wash them all the time but not running. Your going to be fine. I beleive the reset i told you to do and do it exactly like that will take care of it for you. What you are doing is draining all the capacitors in all modules and erasing any memory or logic lock that may have occured, basically they all start fresh. If that doesnt get it i will be right here with our next step.

Customer: replied 5 months ago.
I disconnected the camshaft sensor and it started right up. Once i plugged it back in it shut off.
Expert:  Reggie Whiddon replied 5 months ago.

OKay please do the reset i suggested want take long

Expert:  Reggie Whiddon replied 5 months ago.

Hello have you had a chance to perform that action? Are you up and going?
