Good point - thanks guys
Good Point leventguner,
I have always had the Camhaft position sensor trip but always been able to drive. I did a while back put a new Cam Shaft Postion Sensor in the block and it still tripped the OBD-II so I thought could it be the wiring harness or the engine computer???? (Not sure) But It drove so I let it go. I have never been able to figure out why it tripped. I am not sure if it shut the supercharger down but I am not sure if I've ever noticed it kick in like the Turbo in an old Subaru that I use to have - you could feel it give out a boost. Maybe I have all along been missing the SuperCharger - not sure - the car seems to fly like your average mercedes.
I saw the PSE unit pictures from a post on here and like the K40 soder issues. I guess I should take it out and examie it to see what condition its in. I am not sure exactly what the PSE does but I do have issues with the door locks. Sometimes they lock themselves while the car is sitting unlocked - so I always have to leave the window open if the keys in the ignition and the doors are closed. Maybe the PSE have something to do with the locks not sure. Help me understand the PSE.
Follow-up on above paragraph - in Bazzles post: (The PSE(A-37) has a vacumn pump to operate the door, boot and petrol filler locks. It also controls the alarm (if fitted) and the interior light timer, door unlock crash sensor
Plus rear demister relay and ARA control model if fitted.
It comunicates with the DAS thru the CAN from the MFC unit.)
I do have interior light timer issues and door lock problems and I might have more that I am not aware of - so I need to pull that PSE out and clean it up. I am not sure what these terms are: rear demister relay and ARA control model -- DAS, CAN and MFC unit.
Back to the fuel pump:
But I do think I have a Fuel pump issue if I power the pump with the key turned and leave the fuel filter off and there's not fuel coming out. Do you think if I had water in the fuel line and it froze due to colds temps it could have killed the pump - or does 63,000 miles do it. I got a fuel pump on order and I'll know if I am on the right track in a few days.
Bazzle - on the Ohms. So you think if I got the key turned I'll get about 100 ohms but if I have the key in my closed hand I'll have zero ohms? If theres not continuity does this mean that the digital display will bonce up and down with readings?
I know once a get a few of these tweaks sorted out I should be back on the road for spring - any other opinions are very welcome. I am open to all advice, etc.
