Forester sg5 engine won't start
 

Hello guys any advice please my forester sg5 stop starting yesterday I've check for a code and crankshaft senzor says was faulty I change sensor and car won't start again I've checked all fuze and all sensor on the engine bay and all have 12v only crankshaft sensor is 0v I have no power on the wires to the crankshaft sensor

The crankshaft sensor produces voltage and counts the position of the Reeth on crank timing wheel, it doesn't recieve a voltage, if unplugged to test with Ign on, ecu will record it as fault condition

Best thing to do is clear all codes and try starting it then check codes again

I've clear all code change sensor car won't start. Ive unplugged the sensor and check voltage is 0. I've plugged the sensor again clear fault code and I read live stream with the diagnostic crankshaft remain off

You don't mention what model year (MY) or whether it's an EDM or JDM model SG5 or what DTC (Diagnostic Trouble Code) you had/have.

Find pdf attached info for P0335 and P0336 as per MY04 EDM model

Is a EDM 2004 model 2.0xt trouble code was p0335 manual transmission

Also somebody suggest it could be the immobilizer

What type of key do you have two button or single button??

When you put the key in the ignition does the ECU immobiliser indicator turn off?? (Red key symbol on dash)

When you say "it doesn't start" what actually happens when you turn the ignition key to the start position??
Does it turn over ??
Does it turn over but not fire??

Is 2 button key the engine turns but no start.

When you put the key in the ignition does the ECU immobiliser indicator turn off?? (Red key symbol on dash)
Any additional alarm system fitted to it??
Can you hear the fuel pump prime
Have you checked the contents of the pdf file - is the mentioned wiring sound?

The fuel pump is working I can hear it. Also I don't think I have any red key simbol on my dashboard no alarm is fitted to the car I will check the harness again tomorrow

If I remember correctly it is shown as below with the key out of the ignition.

Tomorrow I will take the key to check for immobilizer

Have you put the old sensor back on to see if it starts?
Could be wrong or faulty sensor if the old one works.

I've try both off them also on live data when I start the engine the crankshaft sensor is off I've read all sensor live all are on only crankshaft is off

I don't have a key light on dashboard

Could be a problem with the Immobiliser ECU or MB Fuse SBF #5.

Do you get a door open warning light on the dash?
If both not working you may have a blown link on the combimeter or Main Fuse board Fuse #2
See attached (I've assumed it RHD)

The open door warning is on yes. Also no blinking lights when I turn switch on somebody says if any lights blinks on dashboard may be the immobilizer

Thanks for your help bro tomorrow I will check resistance at the crankshaft wires also check the key and I will make a video with the diagnostic connected when I try start the engine

I check the resistance at the crankshaft and is 48.1 check attachment

Resistance of what?? in relation to P0335 test procedure??

Yes I checked like says on test procedure that you send me

There are 5 checks in that list.....

I've checked all steps on that list still nothing also I swapped the crankshaft sensor from a friend car and nothing I put my sensor on his car works just fine I don't know what else to check now maybe is a ecu issue. Now I'm waiting for a key guy to come and check
