Hi guys, I've got a problem with my truck, it's a twin turbo lsx. I have just done a lot of work moving the fuse box and pcm to under the rear seat, I Have re worked the turbo system and relocated the coils under the headers. I got the truck running ticking over nice and smooth but when I took it for a test drive as soon as it changed into second gear it started missing and running rough and now it will hardly run at all. I got this dtc 336 crank sensor, the sensor itself checks out to be good on a oscilloscope, I also swapped the wires to the sensor with screened ones in case it was picking up interference from the relocated coils.
I'm starting to think the reluctor wheel has moved, which brings me to my question before I dig into it,
Is there any sort of test I could do to prove the reluctor wheel is in
the right position without having to strip the motor down, Is there a
different notch in it or something that relates to number one piston at
tdc that I could see through the sensor hole.
