OK! I HAVE REPLACED CRANKSENSOR,COIL,LEADS PLUGS,ECU RELAY,FUEL RELAY,CLEAN ALL ELECTRICAL CONNECTIONS....AND STILL NO JOY.AFTER REMOVING OLD CRANK SENSOR IT WAS A MESS NO INSTALLATION WHAT SO EVER JUST BARE WIRES SO THOUGHT THAT WAS PROBLEM....ALL THAT HAPPEN IS WHEN YOU TURN KEY SO THE DASH LIGHTS UP YOU HEAR A POP! WHICH I HAVE FOUND OUT IS JUST ONE SHORT BUST SPARK GOING INTO DIZZY..THEN NOTHING WHEN TURNING ENGINE OVER NO SPARK :cry: THOUGHTS ON THIS MATTER WOULD BE GREAT....
-
Dodgy immobiliser ??
-
thats what im starting to think!! its the crap conlog 900.... dont spose there is a quick fix for this? :undecided:
-
Quickest fix is to remove it !!!!!!! Usually located either behind the clocks on drivers side or behind glovebox/airbag on passenger side. Unplug the control box and give it a try.
-
had imb checked and its fine! this is driving me round the bend so much i put breakdown cover on my insurance only for a complete waste of space greenflag muppet to just stair into my engine bay and do nothing not even vagcom!!!
anyway after linking vagcom up again ive got error code 00668????? pls someone help!!!!! no fuel no spark
-
00668 = battery power supply voltage, sounds like battery fault or a wiring issue, or perhaps ecu relay needs to be replaced
-
If it were the battery then the dash lights would be dim and the engine turning over would be slow. If you get a short spark then nothing then the coil seems to be working. I would still bank on the immobiliser. How did you test the immobiliser ??
-
having the imb tested or removed on sat...do you think a faulty dizzy would cause no spark and no fuel pump??? :undecided:
-
Faulty dizzy could affect the spark but would not affect the fuel pump at all. If you are having the immobiliser tested/removed then I think this will solve your problem. The immobiliser usually lets the engine start and cut out straight away. Keep me informed of how you get on when the immobiliser is removed.
-
will do!!!!!!!!!! cheers for that :wink:
-
still wont start, but found out the fuel pump is priming when trying to start so thought maybe dizzy! so replaced and still nothing just spinning over no spark..time for a auto electrician i think,spent so much money..but any other thoughts would be nice :undecided:
-
Did you ever sort this problem out.. coz im getting the exact same problems. .. any advice will do...
-
Just take it to a Vw specialist or equivalent. No point spending out on money unless you know what the exact problem is.
-
Have you checked the water coolant temp sensors if it is reading the engine is hot then you will get a lean mixture instead of a rich mixture needed to start the engine.
If the sensor is within tolerances between hot and cold then you probably wont get a error code.
-
Have you done this have you checked that...just take it to a garage.
-
Sounds like a fault I had on mine.
have a read here.
