i need to know where the crank sensor and the timing marker bolt on in an 81 280zxt
sean.

 

crank sensor is deep within the dizzy...

 

Not on the 81...

The CAS on the 81 is on the drivers side of the crank pulley.

 

who in the right mind uses the stock CAS system? and i never had that on my 81...

 

81 turbo did. i hear its junk

 

alright i got that on and all my other sensor's and vacuum lines on and when i try to start the car its still showing the sensor light. any ideas?

 

The yellowish orange sensor light? uh oh....


Oh wait... that's just the O2 sensor warning that lights up @ something like 30k miles. Then you take it to Nissan, they reach their lil hand under your dash and unplug a wire.

Don't worry about it... that isn't keeping your car from starting. Or did the car start? (you didn't say it did or didn't).

 

no it wont start. i tested the injectors and the sensor's that go on there and everythings good. probably vacuum somewere but i dont know. it could possibly be off time also but im pretty certain i have it right.

 

you got spark yes?

 

yea i have spark

 

Are your injectors spraying fuel?

 

yea they should be. i put on a new pallnet fuel rail and did a test on the sensor's that plug into the injectors.

 

you could pull the rail with injectors still attatched and actually LOOK to see if they are spraying.

 

Or just pull the spark plugs and look at the tips.

 

ll try that but they should be spraying there the same injectors i had on before

 

not as effective imho. not like pulling the rail and cranking it is hard lol

 

That means nothing if the problem is electrical. And how do you know you have fuel?

 

well, i guess i don't. ill go check it out.
