Recently i found here in the Netherlands a Solstice on a auction.
Cause i had old memories from my Solstice 10 years ago i bought this one. It's in a very bad shape and i'm rebuilding it.
Already found a lot of usefull information on this forum but i still can't fix my starting problem.
Hope that some specialists here have good advice.

When i bought the car there were no keys and no key remote. There wasn't an ignition and no TDM.
This solstice is import from the USA and probably stand still for a 8 years.
Cause parts of an Solstice are rare in the Netherlands i bought the ignition of an Chevrolet HHR incl the TDM and a key.
(This should be the same)

But the solstice still don't start. What's done:

  • Made the fuel tank empty and clean and checked the fuel pump. These are good.
  • I got pressure on the fuel rail so this is good
  • The battery is changed and good
  • All the fuses and relays are checked and good
  • The starter is good
  • The ground cables are clean (Also on the corner of the engine)
  • Got an replacement ECM that is programmed in Cincinnati and send to the Netherlands
  • The Clutch switch is good and gives 12V Feed on the relay in the fuse box
  • The injectors are changed, there is a 12V feed on the injector but the injector gives no fuel. Probably no pulse feed, but my voltmeter can't check this. Otherwise it should give fuel.
When i put fuel through the air filter and connect the + of the starter on the battery the enigine runs for a few seconds.
I did the manual relearn method for the key. The passlock warning light goes allready away after the first 10 minutes, but still did the full relearn.
On the (simple regular) OBD computer i only had the solonoid fault and that is fixed.
No faults on this moment.

But when i put the key on ignition everything works, when i turn to crank i only hear a click at the BCM en see the engine warning light. No crank and electric (like the lights) falls out.

My speculations:
  • It looks like there is an immobilzer but the Passkey III Warning light is out. But it looks i don't get a signal from the computer. (Also tryed ignition on, and put 12V on the starter to get a crank, but injectors don't give fuel).
  • Theres told me that there would be different programs in the computer for American cars and American cars that are for the export market. Chevrolet HHR is that type of car, could it be that this TCM don't work with the Solstice because of that?

Disable the immobilizer in the computer isn't possible here cause no company has the right equipment for a solstice. Would a immobilizer bypass be possible and be a solution?

Or do i think totally wrong and i'm missing something?

PS: Don't think this would be the problem but there is also one cable over from the ignition (see picture), there is no connection for this cable in this Solstice. What is the function of this part?

Hope someone has good advice!

A very ambitious project! Good luck with it.

Someone may recognize the connector, but if they do not, posting the wire colors may help to identify it.

Also, what year is the car?

Thanks!
The car is build 2006.
The wire colors on the ignition connector are yellow and green.
But i thought the colors or the cars connector that connect this should be a different (unknown) color

OK if you PM me and I will walk you through how to test the starting circuits on the vehicle. Possibly do a voice chat using whatsapp or the like would be easier then going back and forth over the forum. so that option is there as well. How the Kappa platform vehicles start is kind of unique to these vehicles as they were one of GM's first attempts at using transponder technology and it is more of an afterthought then a full integration of the technology into the vehicles. We need to verify if the BCM is seeing the proper signals and if the BCM is outputting the proper signals to the ECM. It's a lot to go over which is the reason why a voice chat if preferable.

Congratulations! Always good to know someone is saving a Kappa.

I might be totally off the mark here, but I believe you have to check your HHR body and transmission modules (BCM and TCM). Even if they are the same part number as your Solstice, they might have a different service number which means they are programmed with a different internal software designed for the HHR.

You probably will have to reprogram these modules using TIS and a compatible VCM to get your car to start.

Only the TCM and ignition were from the HHR. The BCM is original.
The problem is that these parts were allready missing when i bought this Solstice, so i couldn't compare.

The next step now is waiting for a "VCX Nano diagtool Tech2Win" that i ordered for a better diagnostic and some relearn programs.
Following some tips and tricks from kgschlosser.

Perfect, I too believe this is the way to go. This unit will allow you to program any Control Module (ECM, BCM, TCM, etc) if you need - all you'll have to do is subscribe to TIS.

When you say ignition, what do you mean exactly? The key cylinder that goes on the steering column? Did you check the parts diagrams to see whether you have all the parts from that area (ie. anti theft module, transponder antenna ring, etc.)?

This complete unit including TDM was missing , i only had some cutted cables and a switch stolen from a lamp on a bedroom when i bought the car.
I don't believe that really worked in the past.
Don't know why someone would do this. Maybe the last owner lost his keys?

I am working with the OP right now to determine what the problem is. If the part indicated in the above post has been replaced I would imagine that the theft deterrent module has also been replaced and if it has not we will be able to identify whether or not it is functioning properly using Tech2Win. If it has been replaced then it needs to be coded to the vehicle which can only be done using an advanced diag tool or Tech2Win. so in either case we will be able to narrow down what the problem is.

I do not believe there is an issue with the original ECM and I have instructed the OP to put the original ECM back into the vehicle.

FWIW the vehicle is a manual transmission and it does not have a TCM (Transmission Control Module).

I can tell you that since the entire ignition has been replaced we will have to do some reprogramming of the BCM because of Passlock2. PassKey3+ is a combination of the older GM Passlock2 and a transponder. So the BCM is going to get the BCM to learn the new Passlock2 resistance values.

Indeed, i said it wrong. With TCM i meant the theft detterrent module on the ignition.
Sometimes i'm searching with the English translations :)

The 3 letter abbreviations for the modules gets confusing sometimes. An example is the CKP sensor. which is the Crank Shaft Position sensor. they had to use something to not confuse it with the Cam Shaft Position sensor. LOL

the part on the photo is missing the theft deterrent ring antenna. (photo atteched below, it is actually together in one piece with the theft deterrent module).

EDIT:Sorry, I now saw in your photo that you do have the ring antenna.
The cable you have dangling (green and yellow wire) is for the key retention solenoid (the white plastic pin with a spring) that is used on automatic cars to avoid the key being taken out of the cylinder if the shifter is not on Park ("P"). If your car is manual I believe it is unnecessary, that is why you are not finding any connection for this.

Is the key you now have a brand new key, or is it the HHR key?
If it's the original HHR key then it will have a PK3+ transponder chip inside. You might or might not be able to program it to your BCM/Theft Deterrent.
Why do I say might or might not? Because I am under the impression that once a key is programmed to a car, it cannot be programmed to another car.
In your case it might work because the Theft Deterrent module you have is the one that the key was originally "paired" to.

I believe the key (no pun intended) to your problem is getting a Tech2 or VCX Nano + Tech2Win and doing a Theft Deterrent relearn as pointed out by @kgschlosser .

edit 2: Here's the key retention solenoid for your reference.

Thanks for the info. I indeed have a manual transmission. Now i understand why i couldn't find a connector to this.
The key is also from the HHR.

Now just a few days waiting till the VCX Nano arrives.
I first doubt getting one but i'm convinced now that will be the right next step.

And didn't know before that a VCX Nano was also an (cheaper) option. I only read about the Tech II computer.

See the "circle cross" logo etched on the keyblade? That means your key is a "Passkey 3+" enabled key. It will have a transponder chip buried inside the plastic key head.
Ask me how I know. A few months ago I dealt with a transponder issue for quite a while. Managed to learn a bit in the process. I hope you don't end up needing to code a new transponder to your car because that can only be done by a locksmith or you would have to buy yourself a transponder programmer such as the "VVDI keytool mini" (I ended up buying one).

I don't have any experience programming via SPS {I think currently called TIS or something like that). But I believe you don't use Tech2Win in this case. You would need to use a different Windows software. Most likely your VCX came with the software in a DVD or something.

I had to download the VXC software. Think i should be possible to program this but have to activate the SPS with TIS indeed. Found a program TIS2000. When i'm out i'll post it again.
