I recently installed a gen4 408 into my 2002 ws6, I am using the ls1 wiring harness still. I have the correct 24tooth reluctor wheel, but i keep getting a crank position sensor error when I try to start it, I swapped the sensors twice to double check and make sure it wasn't a bad sensor. The tach works for a split second while trying to start it, then does not work again until i clear the crank position sensor code p0335. Can't get it to start, any ideas?

408
11.5cr
ls3 heads
ls7s cam (tsp)
mail order tune from tsp

 

what type of cam sensor setup do you have? ls2?

 

cam sensor is set up correctly as far as i know, x1 wheel and the wire has been crossed over for the sensor

 

do you have this for timing

 

yea thats what have, with the outside two wires swapped on the connector

I found that in a quick search and figured it was worth a shot. I would focus on the crank sensor because the car will start without the cam sensor. It may pop and backfire while cranking but it will run.

 

I had tried something similar to that last night with no luck. Maybe I spaced out the sensor too far?
