Here is my Question: I have a 2004 mustang 3.9L it was the only year that they made it a 3.9 (it does exist). Anyway the car has 60k on it and when it rained last the original factory spark plug wires grounded to the block or at least based on the burn marks on the wires it look, anyway I replaced all of the spark plugs with platinum 2 and 8 mm wires. I had it put on a scope and these codes popped up P0068, P0102, P0135, P0141, P0155, P0161, P0403, P1233, P2198 The car ran perfect before it rained. It has not been the same since I have reset the computer by disconnecting the + cable the check engine light came back on within 15 miles Please advise.

Thank You
Rustyed that way

I need you to check 2 things. First, P1233 Fuel Pump Driver Module off-line. That tells me the computer isn't sensing fuel delivery. I am questioning if the rain caused something to short out with the PCM. Has the fuel pressure been checked?

Next, in the dark, start the engine and open the hood. Mist water all over the coils, plug wires. To see if something is still arcing. It could be a coil that is shorting based on other codes.

Let me know what you find.

Hi Joe your e-mail went to Spam I just found it. One this I that I forgot to tell you regarding this is that I also changed the fuel filter at the same time that I replaced all of the plugs and wires it was very clogged. From the test that you suggested there was no arcing at all after misting the block. Please advise.

Hi:
Are you able to hear the fuel pump run for a few seconds when you first turn the key on?

I did Receive your e-mail you are on my safe sender list,

Unfortunately my hearing was damaged in the military, so to answer your question no I cant hear it turn on, I want to tell you the car runs and it is my daily driver, so it make sense that it is getting fuel but I dont know if it is getting the right amount of pressure. To get the car to move I have to put my foot on the gas hard then the car jumps forward sometimes breaking the rear tires loose.

Perhaps you should check fuel pump pressure. On our home page, there is a section called "do it yourself". If you go to it, page down and you will find the directions (with video) describing how to check it.

Try that and let me know what you find. NOTE: You will need a fuel pressure gauge. Most parts stores will lend them to you.

Let me know what you find.
