You have probably had the immobiliser disabled in the BECM .Originally Posted by benji
Dont just fill with coolant and drive. it takes a while to get the air out of the system and you will overheat it real quick with an air lock.
When you connect the charged battery make sure the key is not in the car as it will lock itself

SupporterToo true, just hire/borrow a trailer and tow it with the D2.
Erring on the side of caution, our p38 wasn't regularly started for near on 6 months. We trailered it back 150k; very heavy but worth it.

my 94 p38 has sat in a garage for the past 7 years and only been started 4 times in that time. I change the oil each time before starting and drained 3/4 fuel out and replace with fresh stuff each time. It has started first go each time with no problem at all, no noises,leaks,smoke anything. So each time I decided to take it for a 30-40 min drive. airsuspension filled up no problems and no errors. I just have to reset all windows and sunroof and it drove great.
I must admit I was surprised each time but it has never let me down. apart from the headlining, that sucker has sagged like crazy. O and the leather is a little moldy but that cleans off. I say start that sucker and drive it.

SupporterAnother thing it says in the manual is when you reconnect the battery have the drivers door open and the key at ignition 2, apparently the computer takes that to mean you own it, can open the door and have the key!
Not sure how important it is but I did it and had no problems,
Good luck

SupporterDo you know if that's with gems and bosch?
Great to know though.

Mine is a gems, with the manual to match, I'm afraid I don't know if the bosch is the same, as you say it's a little thing that's good to know.

SupporterOK, I have resynced fob with BeCM using the key in door technique - thanks!
Now, no cranking.
When I read security codes from the GEMS with the Nanocom Evo I get fields with single "0"s in them.
There is no EKA as I believe '95 models did not have them. My understanding is that I have to write these security codes back into the BeCM but they are just 0 and, I can't find an appropriate part of the menu to allow me to write these back into the BeCM anyway.
I tried "security learn" but no joy. Cycling ignition is just key out and in again - right? or does it need door locking and a delay etc...
Any hints?
TIA

SubscriberPossibly the BECM has lost the engine EMS code from its memory. So, use the Nanocom to read the three digit security code in the engine ecu ...called the ems. You then write this number into the becm memory, save it there, disconnect the Nanocom, switch off the ignition. Then switch on and see if it starts...
Alternatively, and I don't have a Nanocom, but the principle may be the same, here are the directions for using a Faultmate with the GEMS system:
Go through the Nanocom options in the Petrol EMS section to " Security Learn Mode"
"...Security learn mode: When the ignition is turned on, the BECM, providing it is in receipt of a valid mobilization code and is therefore not in an alarmed or immobilised state, sends a coded signal to the GEMS which the Gems then compares against a mobilization code it has stored in it. If the two codes compare OK, the Gems will allow the engine to start. This forms the basis of the immobiliser. If the GEMS ECU, the BECM, or the lockset & key fob is replaced or other data in the BECM is changed, it may be required for the GEMS to re-learn a new mobilization code.
This is done by using this function to put the GEMS into Security learn mode whereby the next coded signal it receives is not compared but is instead stored as the master copy. When security learn mode has been entered the ignition must be turned off and turned back on to trigger the BECM into sending the code. The GEMS will check the incoming code and should accept it; however, if there is an error no matter how slight in the codes makeup, the GEMS can reject it, in which case there will be no valid code stored. This situation can be checked by looking at the security learn status in Inputs - Engine and Other which denotes whether the system has a valid code stored or not.
"
On re-reading your post and thinking about the above, it may be that the GEMS EMS won't accept zeros...i.e. empty fields. My suggestion is to populate the BECM "EMS Code" with three digits or however many it requires (I have a Bosch system which takes 3 digits) e.g. write in 1 2 3 which the GEMS EMS in "Security Learn mode" might accept ...
