Where is the tcm in a 1994 chevy S10 Blazer
There is none.
With a signal from the ecm it powers up the fuel pump.
Need to know if it is standard or automatic and why.
94 should be OBD I.
Check inside the vehicle in the passenger side kick panel or behind the glove compartment.
It'll fit, but it won't work. The 94 transmission is electronic, and interfaces with the ECM. It won't be compatible with the 91 in that regard.
any s10 or sonoma up to 93 and any blazer jimmy up to 94
your Chevy dealer
i think it is the sensor located on the drivers side of the motor rite next to the middle spark plug.
NO ITS CONTROLLED COMPLETLY DIFFERANT
