Mk3 gti 8v HELP PLEASE wont start something weird is going on

[Kmad]

Is it possible that if that sensor is faulty ecu will not signal fuel pump to work??

[dixie180]

It tells the ECU which cylinder needs fuel and which one needs a spark,so i guess faulty Crank Sensor would not send a signal to send any fuel to the cylinders.

F@£k me i am lost now , checked every part of fuel system electronics there is and everything seems fine! Why the hell am i reading correct voltage at the pump socket but it still wont work is anoying the sh!t out off me... How is this possible??? I am starting to think that when the pump is conected and load comes on something fails in that wireing and not inough curent runs through to run the pump .... I dont know anymore....

If the Crank Sensor is f**ked your fuel pump won't get the signal from the ECU.Did you run the VAGCOM on the engine and if so what fault codes did you get up,if any.

Ok that gives me a bit of hope , tommorow frend is bringin the fault reader and we are going to hook it up... Btw when i connect multimetar to two far outer pins of the crank sensor its reading mega ohms , i dont think thats right but i dont know for shure which pins i should test...

BTW guys sorry for misspelling here and there i am originally from Croatia!

[dixie180]

Only 2 pins will give you a reading and it should be in the range of 500 to 700 ohms. no worries bud don't like seeing folk suffering with Mk3 golf rage :laugh:Pins 1 and 3 voltage 9-14.5v.

[Kmad]

Just tested it and its reading 7.00 mega ohms ... f**ked??

[dixie180]

Yep absolutely  .Probably best to run the diagnostics aswell but new Crank Sensor on the shopping list i think.

Ok thanks dixie 180! Hope is back
