hi, i have a 2001 ford crown vic that i swapped the entire harness to a 2007 crown vic, but i cant get it to start. I have power at the fuel pump but no activation signal from the pcm. What am i missing? How would i know if the 2007 car had PATS? Any info would be greatly appreciated. Btw the mileage of the 07 car is 400k.

Why would you attempt something like that in the first place? Why don't you just get the right parts?

A wiring harness made for that specific vehicle.

So are you saying that what i have attempted to do cannot be done? Should I just give up now, throw in the towel, and tell my friend(the car owner) that it cant be done?

The era of endless new parts for vehicles ended and now so hard to duplicate what you may need it can easily exceed the value of vehicles that become scrapped.


It is a challenge to know when you have really hit that point. This comment isn't even just "automotive" it's about lots of things just not worth it anymore for one or more snags to put it back to useful - things of all sorts,

Nobody said it couldn't be done. It can't be done using the wrong materials though. You need the exact harness for that vehicle and send the original one out to be professionally repaired.

Try ordering a new one from the dealer first.

anything more than 10 years old is considered obsolete, at least it is at the Ford dealer in my area. Discontinued to put it another way.

Sorry if I sounded discouraging - not intended totally. Finding a good whole harness in this case new or used could be a real hunt.
The point is with so many cars with each model year possibly totally not compatible with many other model years just stocking new parts if free gets impractical. Sorting by part #s then know your inventory on computer something takes up time or not on computer at all just someone knows there's one out in the "salvage yard" that year that may be ok if you physically go look! Yikes - gets hard for what would be just doable.


It's true that car maker's ARE NOT required to have parts past I think still the 7 year mark but may and should have part #s to help with a search.


What is unfixable with the OE harness that part of it wouldn't do?


Hey - anything is fixable with time and resources. I can't say how much time or what it will take to find and do this so it works so easily myself,

lets work backwards -maybe some history will help us help you.
WHY did you chcnge the harness? What code are you showing AND what codes were there before harness swap?






You still have old harness?

Ditto and the question has been asked and remains > What happened to the old harness and do you still have it? Not many reasons I can think of except a fire that the whole thing would be needed - so what's the story?

the story is...i got WAY too much time on my hands...that, and i am always looking to mentally challenge myself. That being said, the main reason this project was started is because my friend wanted to improve the car's efficiency, and what better way to do that than with 6 years worth of technological improvements. I did not anticipate the troubles besetting me now. Do i regret starting this project? Absolutely not, I believe a solution awaits me somewhere in the mind of a fellow avid enthusiast. Hopefully they will be as eager to help me as i am to find them. Do I still have the old harness? Yes, and there was absolutely nothing wrong with it. I know, i know, if it aint broke, dont fix it...or break it for that matter. What can i say, i thought it was a good idea, and now i am at the point where the car is back together, the dash is back in,(yes, i pulled the dash to replace the leaking heater core.) All the doors are back together, the entire harness was replaced from front to back, down both sides, into the trunk, all 80 lbs. of it. I can turn the key to KOEO, i have all dash warning lights illuminated, all the windows work, locks work, heater blower motor works. Only the engine wont start, there is power at the fuel pump, but no ground signal from PCM. The replacement harness is from an 07 crown vic, and i replaced the module that sits above the obdII connector, the module on top of the heater box, and 2 modules in the driver's door. What am i missing?

Oh my God. After reading this I am just speechless.

You just invented a new for of stupid.

I'm closing this idiotic question now and saving it for all future people to get a good laugh.

Quote you ">>Do I still have the old harness? Yes, and there was absolutely nothing wrong with it.<<"
Finally an answer for you. Put the damn harness back in and stay away from cars. If you want a mental challenge find something that doesn't wreck things over it.
I'm speechless at how dumb this move was,

If only you could create a device to harness the energy of the massive amount of stray voltage coming from the large power lines that certainly are directly over your house.

There is dumb, then there is this. I think a little bit of pee came out when I read this. Thank you for destroying all hope I had left that the human race was becoming smarter. But thank you for not trying to become a house electrician who lives in an apartment building and has WAYYY too much time on his hands. Can only guess how that would work out, and I'm leaning towards a Darwin Award
