okay started my car a little while ago and my tach is sitting still. I also have the safc-2 and it is registering 0 also. I checked the bell housing to firewall ground and it is on. Spark plugs all in order and etc. Any one have a clue? Thanks. Oh btw its a t2 duh!

I have a similiar problem, except it kicks on a couple minutes after driving, when it sits for a while, and my power fc always shows rpm.....anyone know whats up with our tachs?

91verty

well if i disconnect the ground wire then my safc-2 starts reading like 9-10k rpms ahile idleing. But i know thats typical. Just cant figure whats loose or possibly disconnected to make both the tach and afc not read......hmmmmmm.

Icemark

what are you using for a tach input??? If you disconnect your SAFC does the tach start working again???

No tach typicallly means the trailing coil is not firing... no tach with aftermarket electronics typically means something is shorted or wired wrong.

good point i think that i will check the trailing coil first though.

Icemark

No tell me what wire you are using for a tach signal first!

91verty

trailing coil

Icemark

and (its just like pulling teeth... and you want me to help you)...

WHAT WIRE DID YOU USE???

91verty

slow down there cowboy! I fixed it, it was a faulty trailing coil. I have no idea what wire is being used because i did not innstall the safc-2 sorry ther Icemark. Have a nice day
