I have a 93 Camaro 3.4l that I put a 96 engine/trans/susp/pcm etc into about 6 years go.
Suddenly my cooling fans stopped working. Fans work when D1 & D4 are jumpered, but not when the coolant temp sensor is unplugged.
I have no ground at A10 and A11 on the PCM with ignition on and coolant temp sensor unplugged, they are both live in fact. I think that means my PCM is bad? Can anyone confirm?
(At first I thought it meant that there was a short between the PCM and relays and so cut the wires and spliced in a couple of new ones but nothing has changed)
The tag on my PCM is 16214399 / 16242261 BWWY, which doesn't appear to match any broadcast codes I can find.
I was hoping to just buy a cheap PCM on ebay and stick it in but it doesn't appear that there are many AT 96 camaro PCMs around...
Which used PCMs can I plug into my AT 96 LT1 Camaro without programming?
Impala/Corvette? perhaps a 97? Any help GRATEFULLY received
(To bypass the VATS/PCM issue previously, I popped the resistor out and stuck it into my old ignition key. heh)
