R33 Problem

[boostn0199]

Just finished installing my poncams and valve springs. Started the car and first crank started no worries worked all day. Now just set the timing to 15 degrees went for a light drive no boosting and was going fine no probelm them all of a sudden at the lights stalls and doesnt start again.

Took off the top timing belt cover and checked if the cams were still alligned and they are both alright havnt skipped and the belts tension seems fine so I dont see how it could have skipped a gear so running out of ideas.

check any plugs and connectors that you would have messed with when doing the cams. then check for fuel and spark and go from there

[boostn0199]

have checked all the connectors there fine, have taken off both timing belt covers and belt has not skipped, have checked for fuel and have spark. Just dont get it ran normal than all of a sudden at lights stalls and thats it.

Don't convince yourself it's anything at all to do with the cams. You'll probably find that it would have happened regardless of whether you changed them or not. Just check the usual things.

Although, CAS could play a part in this, maybe not the plug but it could have died as a result of being removed.

[boostn0199]

Is there anyway to check if its the cas without having to get another one and plugging it in?

[R31Nismoid]

yes,do what jono said... check spark etc.

just because connections are fine doesn't mean the sensors are.

[Wheezy]

Spin the CAS by hand and see if everything fires?

[boostn0199]

Just abit of an update. I have noticed the back of the cas had made contact with the cam gear bolts and has sort of grinded it as you can see in the pic. I think it happened due to I didnt put the top timing belt cover on. Could this affect the CAS?

[JonnoHR31]

have checked for fuel and have spark

and?

you need to have the timing belt cover or a spacer of the same thickness between the CAS and its bracket, otherwise it gets pushed into the cam too far. cant see anything wrong with it from that picture tho?

yep I reckon youve kill the cas, I was told to be sure to use the rubber spacer that is on the cam gear cover otherwise as stated above the cas sits too far in, and yep can kill the cas, I was running no timing gear cover but the tuner said it was a common mistake to have happen and he sees it often

[boostn0199]

Just put everthing back together and put it on with the timing cover this time started up first crank guess I was lucky didnt kill the CAS. Its one of those things that are really simple but you just dont think about it.
