Still got your old motor? Any chance that your cold cam sensor is still attached to the valve cover on it?

I got it from whoever above said CAS. I didn't realize he was an '03. Still something in that realm, related.

I said CAS... because it matters. if you have no cam sync, the car wont know when to fire the spark plugs and wont run.

oh they do, but it's not the same one. it's just a magnetic type sensor on the top of the back of the valve cover.

No, it was moved over.

partsgroup has one for $45 so next steps are to swap that out and also eyeball my camshafts.

Y8s, do you have a guess where/how/what setting/input the Hydra displays the cam angle sensor?

Yes, it is rare, but at least you agree that it has happened. There is at least one recent documented case on this forum.

Fortunately, your '03 cams are stronger than NA cams, so I really hope this isnt the issue, but checking your cams is free, and involves only a 10mm socket for the valve cover bolts, and a 12mm socket at the coil pack mount. Be patient if your valve cover does not pick up effortlessly, and everything will be ok.

OK well if I have a broken camshaft and it fucked my head I will cry because that would be bullshit since I have only been mild boosting for 40k miles or so.

There might be a fuseable link blown. If that is the case you might have a big electrical short in the wiring. You will need the Haynes manual to find the link or talk to the parts counter people to help you find it. Also could be a bad cable or a loose connection to the battery. Check alternator wiring

Hmm does anyone have a map of what the fuses under the dashboard? I eyeballed the fuses under the hood and they were all ok.

I'm sitting out at my car right now.

I swapped the cam angle sensor out, no go. Jeremy didn't know where there is a readout od the cam angle sensor in the hydra.

The crank angle sensor works- rpm is visible when cranking.

I didn't" pull the valve cover but I looed through the oil cap and saw that the exhausr cam was turning when cranking.

For the **** of it I tried leaning It out and richening it but it didn't"help.

Car is still going eh eh eh eh whirr as if **** is out if phase.

and you're sure the crank sensor isn't loose and the crank trigger wheel hasn't moved relative to the crank pulley? you will still see spark and RPM if the wheel is rotated incorrectly.

I just checked and the sesnsor is secure and the correct gap. I have an ati damper and it has two crank trigger points on it. I think they are part of the damper. I wiggled on them and they didn't move.

FFS, It's a 10 minute job. Pull the damn valve cover.

Edit: I've been known to pull the valve cover because I was BORED.
