Okay, so I just did a swap on my 2005 MZ3 2.3l with a powertrain from an 04 2.3l (I bought it without a powertrain in it). Everything went smoothly, except when I went to turn it on. It gives me the red car/key light in the cluster, which the dealer says IMMOBILIZER! It obviously didn't help when they stole the car in the first place to steal the powertrain out of it, but I digress.

Many say that you have to get the dealer to reprogram the keys to the new ECU ( I didn't have the one that came with the 05), however, the extremely helpful guys at Black Gold Auto Imports said you can just swap the ignition barrels. Can anyone corroborate this? He said you remove the plastic covering the steering column, and use a chisel to turn the tamper-free security bolts holding in the ignition. I'm going to try on the 04 wreck first, but the cars aren't at my house (no garage) so I'd rather hear a yes or no before I drive across town.

Okay so that didn't work. I got the security bolts out of the wreck and plugged the ignition into the good car, but still the same thing.

However, I had a thought when I was driving home: This car had an aftermarket remote starter before the powertrain was stolen. This implies that it had a immobilizer bypass on it. I'm not really familiar with these, but I'm assuming that it's still on the car somewhere? Could that be the source of my problems?

From what I've been able to determine, the remote start only works after you've got the thing starting normally. The key/transponder/instrument cluster/PCM all have to match.

I feel your pain. I've got an early Bronco I stuck a 2003 Mustang drivetrain in. Same story. And mine won't start even after wiring in everything. The damned PCM has to go back to Ford for a reset.

GRRRRR

No, what I meant was that it had a remote starter, but it was ripped out with the stolen engine. I don't think they took everything though, as there were some wires left over (my Dad pulled a lot of the engine out and just ripped them off without thinking about it). I was thinking that if the immobilizer was still in there, but not really connected to anything at the starter end of it, it could be just screwing it up period.

Another thought of mine is that the starter relay may be gone. It acts similarly to when people have problems with the relay being frozen. There was considerable snow under the hood (the wrecker left the hood up!) when we got it, so a lot of it melted when we got it in the garage even though it wasn't heated, and -25...

Does the immobilizer keep the car from turning over? Or does it let the car start for a few seconds then shut it off? You can hear the relay click, but nothing happens. I know the starter works as my Dad turned the wreck on to limp it into the garage.

The PATS is internal to the PCM and it immobilizes the vehicle. There is no external immobilizer unless you added one. The _P_assive _A_nti-_T_heft _S_ystem is OEM. That is what flashes the lamp on the instrument cluster. You have a programmed key; a transceiver (ring/antenna around the ignition switch); instrument cluster; PCM. They all have to be synchronized/programmed or no joy. You got a wiring manual?

No I don't. What I mean is you need an immobilizer bypass to use an aftermarket remote starter. That's probably still in there somewhere. Honestly I don't know too much about these cars/engines. My last foray into swapping was a 98 Ford Escort and a 90 Civic, and they were much more 'plug and play.'

Generally any bypass requires that you have a functional system first in order to install it. That requires a cycling of the ignition with the proper key/transceiver/cluster/PCM all talking the same language/code. Some of the bypasses require you to place a spare key adjacent to them. But all they will do is bypass the starting. It shouldn't keep you from running. Are you running your original '04 key/cluster/column/PCM?

No, the problem is in the cluster. I have the 04 pcm/transceiver/key, but I don't want to swap out the cluster, just too much mess. It's going to the dealer.

Okay, so the dealer got it reprogrammed and running. But now the problem lies in the axles. Turns out, even though the dealer says they should be the same, the knuckles on the axles are different between the cars, and we can't find axles to replace them with. I think we'll just take 'em apart and switch the knuckles and give them back to the dealer.
