This is my first post, so please forgive me if I miss a protocol. I replaced the engine (234K)in my 04 ZHP, because of low-compression on 3 cylinders (120, 140,140). With a low mileage engine (78K) from a 2005 automatic ZHP. The engine would not start after the install. The only way I can start the engine is to jump the starter solenoid. When the started is jumped, the engine runs fine, (No Check Engine Light).
Initially, I used the main harness from the donor engine, but when the car did not start, I installed the harness from the original engine. I have checked and rechecked all of the wiring connections, relays, fuses, and grounds at least 4 times. I purchased a Foxwell Scan tool and performed an Auto Scan. The car scanned cleaned with no codes found. However, when I scanned the EWS module, it showed the starter not being enabled because of P/N. As stated earlier, this car has a manual transmission I replaced the clutch safety switch just because...When I scan the clutch activity, the scan tool shows the clutch engaging and disengaging as it should. I do not know why the DME is looking for a P/N signal, i am at my wit's end
You have original DME and EWS in car, right?

I'm wondering whether you've hooked BOTH small wires to the starter....in the correct place. One is the input to activate the starter, the other is an output....used to be to an unloader relay, but it shows as being to the instrument cluster and e-box fan, on your car.
My point being that if you hooked the activation wire to the wrong terminal, the starter won't be activated. Which would be the easiest way to explain what you've got. (The two ring terminals are different sizes, but the larger ring WOULD bolt up to the smaller terminal.
I'd check this first.

Yes i do.
Thanks, I have checked the starter wires, they are on the right posts.
Then test whether you are getting 12 volts to the activation terminal when the key is turned to the start position. If so, you need a starter.

I will check and report back.
No power to the activation terminal.
Following up on 328Power04's question, have you tried synching EWS? I don't know if there is a safety feature/memory in the harnesses themselves (seems unlikely), but a wild guess is that using the harness from the -auto- donor car, you could have triggered the P/N error... As far as I understand EWS is not related to transmission, but you never know...
Auto transmissions usually come with a safety feature that prevents you from starting the car if you"re not in Parking or Neutral; I have no idea what P/N stand for in your post, but if it means that, ,your 1st attempt at starting the car with the donor's harness could have triggered that safety feature.

GOOD CATCH, BREEZE !
Yes, P/N preventing starter activation will indeed be Park/ Neutral, do you're going to need to make sure that your car knows it's a manual transmission. I have encountered this before....sometimes the car's coding screws up just a little in the EWS module, and you have to tell the EWS that it's a manual. You will need a good quality BMW diagnostic tool to do this; I'm pretty sure I was using Autologic when I was led to this solution by Abel (328 Power 04).
I am not sure whether the Foxwell unit can do this, but give it a try...it does communicate in both directions, so it may work. Again, check whether the EWS module shows the trans as being a manual, and whether you can change it there.

I could see that, I tried clearing the adaptations, but the car still will not start. I think the P/N stands for Park/ Nutrual.
okay, i will give it a try and report back. thank you.
i tried with the Foxwell, but could not reprogram the EWS.
Thanks Chris!
elderarchie: if you have a laptop, all you need to know to perform the EWS synch is in this post, made by 328Power04:

You'll only need to buy a cheap cable with that:

It is not an EWS/DME sync that is needed; the EWS alone is involved. It needs to be told that it is connected to a manual car..

I've sent a PM to Abel; maybe he can advise.

I cannot trust that the Foxwell tool is reporting auto/manual starting status correctly. And certainly seeing park/neutral on its screen doesn't mean that it is set as automatic. The problem here is possibly a bit more complex, or at least I don't think you have the right tools for the job.
It takes a very specific procedure to code the ews from manual to auto or vice versa. Something I do not think the Foxwell tool does at all.
That is why I had asked about original modules, while hoping to see more info about what else was done.
Certainly verifying with BMW tools that the ews is truly coded as manual is important... But if the module already sees that signal switching, then it really isn't the coding.
In fact, I am inclined to think that the clutch switch signal for ews is the same line/wire as the automatic transmission shifter neutral switch.
Additional info: the DME uses the clutch switch for a few engine routines.
Your test of whether the clutch switch is working, was that data in your tool coming from the DME or the EWS? That is important. There are 4 wires on clutch switch, meaning two different circuits.

Thank you Abel!
Archie, please trust Abel completely. I do; he understands BMW computers better than I ever will, and assists me, and my shop, regularly....and saves my fellow instructors at the race track, too!

hi, I believe it was from the DME, but I will recheck.

Thank you Chris
If you now use the EWS+key and DME from the donor, simply either transfer FA coding from KOMBI or LSZ to EWS unit and then recode EWS to default (cleanest way). Or recode EWS value (would be something like Getriebe) from automatik to schaltgetriebe (less clean but still clean way). Or simply jump the two wires with thickest pins on EWS unit, but this is not a clean solution and might cause future issues when you'd be in need of immo troubleshooting.
If you have INPA and NCSExpert with SP daten on your PC, it is literally a 3-minute job.

thanks for the information, I do not have the DME from the donor engine I will recheck the EWS system again.

thank you, Able
Hi all, I finally had to punt with the no start issue. I took the car to a local independent BMW shop and they solved the problem. The clutch pedal stop was keeping the car from starting Once they readjusted the stop, the car started with no problem. Thank you all for your help.
