So just an update, I ordered a pcm from "Flagship one". Best advice I can give anyone here is stay away from them. I got it in the mail and there weren't any kind of instructions. So I emailed them and asked if I had to do any special procedure. They said nope just plug it in and turn the key. So I turn the key and I get nothing. The dashboard lit up but that was it. No fuel pump, no guages, no starter....nothing. So I emailed them and the had me send it back. Their "techs" said my truck short circuited it and thats not covered under warranty. Which seems odd to me since the truck will start and run with the original pcm. Supposedly they're sending me another one or probably the same one. I'm guessing it won't work and ill be in small claims court. It was supposed to be preprogrammed and ready to run. Just plug and play with a "lifetime warranty"

Hopefully the replacement will make you happy again.

Thanks. I sure hope so

No dice. Same thing.

Where can I find the pin lay out for what pins on the plugs at the pcm correspond with the signal wire on the COP for cylinder 6 and cylinder 1?

I can look this up later tonight for you

I would appreciate it sir. I just wanna check continuity and ohms on those wires and anything else just one more time before I have it towed to the dealer to have the PCM repaired/programmed....whatever they have to do

 

[charged392]

Here you go

 

[pri_i_oh]

Here you go

Thank you sir!! Now I know I won't be able to check voltage without it running but I should be able to check continuity and ohms correct? And what's an acceptable resistance?

 

[charged392]

Nothing at all just continuity. Make sure it’s all unplugged to test

Ok thanks

If I'm doing this correctly the top right hole should be pin 10. Which should be the driver for cylinder/coil 1. This is assuming that the top plug on the pcm is C1 but it doesn't look like it has a little insert in it for a wire or pin to make contact with

 

[pri_i_oh]

Now im really confused. So just for $hits and giggle i tried the 2nd plug from the top with the orange stripe. Im assuming thats C2. I actually have continuity at the correct corresponding pin numbers for cylinders 1 and 6. How can that be? The 2nd plug from the top on the pcm can't be C1 right? I kinda wanna swap those 2 plugs on the pcm but they're clearly marked with color codes as to which plug goes where on the PCM and I dont want to burn anything up doing that

 

[pri_i_oh]

So after a bunch of Google searches apparently C2 is the one I needed to test the pins at anyway so I guess that means my plugs are right and since I have continuity im assuming there HAS to be something wrong with the pcm. Whether it needs programmed or repaired

 

[pri_i_oh]

Well I just got a call back from the dealer and they programmed the PCM and checked everything out as far as that goes and they can't find anything wrong with the PCM. As far as they can tell everything on that side is good. Some im REALLY confused. Im at a loss as far as where I go from here

 

[charged392]

Ok so what’s the code your getting again?

 

[pri_i_oh]

Ok so what’s the code your getting again?

P0340 which i think is just a generic misfire code

 

[charged392]

If you clear the code will it reset by just turning the key on again or does it have to be started up?

 

[pri_i_oh]

The code won't clear out

 

[pri_i_oh]

I think its a broken wire somewhere
