Sorted!! #13 unlucky for some

[jacsmiley]

after doing a short block replacement i now have a "gremlin" under my bonnet!!!

i little electrical one! absolutely no spark whatsoever

fault code 13 [one long "pause" 3short] cam sensor

yes all earths are connected.

yes i have taken the radiator and front cambelt covers off to check timing etc for the 2nd time after 1st fitting it

yes i have tried 3 crank sensors (but didnt flash fault code for it)

yes i have fuel

yes i have tried 3 cam sensors. one came off a working wrx

ive even borrowed an ecu to eliminate the possibility of my ecu being fried, and that ecu flashed fault13

now this is where it gets tricky. and i hope the person out there who has been here done this is watching and will throw me a freaken bone!!!!!!!!! im all barred up and turning blue!!

i have power to coil, both crank/cam sensors, all injectors. no signal to coil from ecu hence no spark

i have continuity from the ecu to the coil. and from the ecu to the cam sensor

cant be a relay, all fuses are sweet.

*pulled radiator out (didnt fill it this time) 3rd time to tripple check cam belt timing*

i could now do a cambelt in an hour start to finish no breaks

could there be a posibility of tracking or conductivity failure "under load" in the cable or cam sensor plug somewhere between it and the ecu??

the cam sensor switches, and seems sweet (3rd one from a working wrx). anyone know if the sensor is ment to have a specific output voltage while sensing the cam gear

remembering that i tried another ecu whiched flashed the same code #13, can anyone help before i start spining that meter at the auto sparky??

dont the wheels have a peice of metal in them for the cam sensor to pic u?? if that is missing wont work?

I AM NOT 100% SURE ON THIS

[jacsmiley]

yup they're apart of the cast when the cam wheel was made (one piece)

yes thats on the right cam too

[Drunkenmonkey]

get a multi meter and test from the plug of the engine loom for cam sensor to the ecu

[jacsmiley]

i think the multimeter needs a new set of batts from all the usage its had

ive run into that brick wall and its hurts

[rex-leggy]

you haven't got the exhaust and intake cams around the wrong way . im sure ive heard on here that its a possible cause?

[DRFVDR]

Maybe an ignitor issue ???

[Guest]

I had that error code once (not once but for a couple of months) have you checked the wires leading up to the sensor? or are the wires the right way round? funny enough if you push start it it will go...well for me anyway.

[Stoffa]

are you using your original cam pulley and original toothed crank pulley?

[Guest]

check the front injector on passnegers side bank and the cam sensor plugs arent around the wrong way

Seen this a few times before and it logs cam sensor error and wont start

[Guest]

Believe it or not a stuffed alternator will do the same thing, try unpluging the plug.

[jacsmiley]

wow thanks for the help. will go look at these options tonight!

really?? so unplug the alt and try to crank it?

and the front injector has a way shorter cable than the cam sensor so im pretty sure a have that correct

[jacsmiley]

also should there be 11.6ohm between the sensor and the ecu?

[Guest]

NO - sounds like you are measuring through the harness and through and injector to get that reading

Cam and crank signals are sent via sheilded cable to the ecu with the engie harness plugs as the only join

[jacsmiley]

cheers ichi

wiring diagram showed me the colour cables that were ment to to the cam sensor. yes i had the cam/injector plugs swapped around!! > >

so angry and so happy at the same time

[Guest]

Glad to help out

ICHI BAN IS GOD!!
