Engine/Transmission (1994 - 1998) Do I Need A Different Pcm??

[JRosengrant]

I Swapped Out The Auto For A 5 Speed, And Now My Charging System Doesnt Work, All The Idiot Lights Are On,and The Tach Just Bounces Around. Help I Cant Live Without My Truck!!!!

I would guess that the PCM is looking for something that is not there in the way of a sensor input. My only experience is with the 94 so can't offer any good advice.

Hopefully someone will have some answers for you.

Sounds like a crankshaft sensor problem to me. Check all connections. Mine works fine with the auto PCM.

yeah, with the crank sensor bad or shorted, the alt wont charge, a/c wont work, and the tach goes crazy or nothing.
