Cas Help!

[Kenna802]

Can some one please tell me if the crank angle sensor are interchangable from series 1 to series 2 the reason i ask is i had new cams installed and they are a series 2 version and the keyhole didnt line up and taking the cams back was not a option so i ended having to buy a newer crank angle sensor. My mechanic and i got everything back together this arv and car will not start just turns over.

R34 CAS wires back to front. You'll need to swap them ass about - same as CA18 if I remember correctly

Thanks Is that just the reference signal wires 1 and 120 degrees or the power and ground as well?

[Kenna802]

Anyone?

[The Dan]

95% sure it's a complete swap. All 4 wires have to be changed as if the plug was upside down

Maybe start with that and if it doesn't work I'll actually take the time to get you a pinout. Changing wires takes about 1 minute. That includes 30 seconds of beer drinking

Cheers for that, Only problem is car still wont start..... changed plugs, checked for spark,fuel, than did compression test and found that my cylinder that read 140 psi only has 40 psi WTF! I think the cause was while we were trying to get the car started it flushed the bore with fuel also did a leak down test and found some leakage in the valves I really am not having a good day..............................

No, it takes months of rich running to abrasively smooth a bore - or during ring bed-in.

Valve leakage is not always a problem, the valve rarely seats in the same place twice in half a dozen rotations

If your CAS is wrong, it will also not be injecting fuel or sparking so it's not possible to be overfueling the bore. Have you checked for injector pulse and spark and had a result. I know I like to assume you do actually have it when you say you tested for it but I have been surprised before

I manually tested the Cas with it off the cam and it was supplying spark and fuel to the injectors . A mechanic friend said are they exactly bolt on exchange as he said the pulse rate or something may be different.
