Any techs in here??
My 83 has no spark..I tried 3 different coils and the DME and AFM out of an 88 I have with no success....When I cycle the key, on the way off I get 1 spark...
Cleaned all the grounds good also....
The tach does not move when I crank it either...Speed sensor problem??
Any help will be appreciated..

reference sensor.

 

Whats the difference between the ref sensor and speed sensor??
Thanks

 

I got both sensors out of the car...Does the ref sensors actually do anything?
I thought i read somewhere its just to set the distance to the crank...I dont know why it would have a connector coming off it if that was the case...
Doc, if you have any info on how to test them id appreciate it...

You can test them with an oscilliscope if you have one, and IIRC you can do some general resistance testing across the pins, I would have to look up which ones to test and the values.

Speed sensor is for your tach, the reference sensor is tells the DME what position the flywheel/crank are in.

 

Thanks Doc, According to clarks garage ohms test, they are bad..Ill try the ones out of the 88 I have here..Ill be looking for new ones if they re bad also..
