@ rgwm, I also kissed her numerous times, also won't hurt and probably wont help either
So I finished up the little fuse box on top of the battery, replaced both midi fuses, see below picture, looks brand spanking new and electricity can now travel again freely, something I think she really needs because one screw not tightened and the whole car goes bananas, which I think and hope was the cause of my problems especially since windows started winding down by themselves, reverse parking sensor speaker making beep beep even when not in reverse and of course locking me out with the CODE system and me not able to do the manual override (maybe she was jealous of the girl in the car at the time,lol) I also took all the relays out, contact cleaner again and re-seated them all, same with big fuses for ignition etc.
Just for additional peace of mind I also took of the big black plug on the far side of the battery to earth, took it off, applied some good amount of QD contact cleaner and refastened and oiled plug, it was all sandy and stuff.
Did the same with the two big black plugs on the engine control unit, contact cleaner, cleaned, oiled, also gave me more confidence knowing I did all that.
After that I went to the front, took steering wheel plastic covers off, checked receiver for immobilizer cable, again, took the connector off by the key insert, contact cleaner, re-inserted plug. I took out all fuses, cleaned with contact cleaner again and Dremel'ed little feet for good contact. One thing I do not seem to find is the steering position sensor to check loose connections, I cannot find it. Also, the little wire connected to the receiver/antennae, it goes into the big black wiring cable and then dissapears somewhere towards the engine bay, cannot locate the other plug going to the body computer.
After this, I hooked her up (she likes that
) to the multiscan via EML327, connected to the engine module no problem so at least I know it is not buggered up, no faults in memory, did all the actuator tests, all looks 100%. Then I took apart the ELM and bridged pin 7 to pin 1 for ABS readings, there was one fault recorded, didn't give specifics so I just cleared it, did the different actuator tests, again, 100%. I did not yet re-solder pin 1 cable to pin 3 for airbag because there was nothing wrong with it so maybe some other time.
After this, I reconnected the negative terminal of the battery and want to start and nothing....dead! I am starting to sweat until I realized the little nut that holds the positive big red wire from the alternator, I forgot to tighten it so I disconnect negative again, tightened the nut and voila, she springs to life! FINALLY!
Now I disconnected the negative again for 2 hours, reconnected and went to sit on my throne, hehe. Then turned key to MAR for 90 seconds, turned off for 90 seconds, then started WITHOUT touching accelerator pedal and let her run for 15mins until fans kicked in and then let her rest for 10 minutes. After 10 minutes I went for a thrashing,lol, she drives better than before (throttle body clean?), no faults and my dreaded Motor control unit error past 6,000 RPM is also gone I am so happy. This morning, started up like no other.
I am driving down to the coast again on Saturday, (same girl) 400 odd km's, tonight will feed her some new juices and I will take my tools along this time, spanners, spare key (brand new) and contact cleaner, wish me luck this time!!
and thank you for all the excellent suggestions and help, I guess it was either one of the midi fuses or one of the contacts I cleaned somewhere, yes, very frustrating chasing intermittent fault, maybe even could have been the moisture at the coast that played havoc on the ECU, I dunno.
I will keep you guys updated on my little trip
