Thanks for the diagram for ECM ! With this I will check all the pins, sensors, conntinuity in wiring from
ECM (with ECM disconnected)to DLC and hopefully
get down to the question why is there no response
from ECM? I had already checked the things above
and feel this is my next step.
Thank you so much for all the imput from you and members.I will post the results of my findings.
From 48 chev.
Well some good news, with the help of you ECM
diagram.I found another power supply at ECM that
was not receiving the full 12V. It is receiving about
3 volt. It is Pin # C16. It joins
with B 1 also an orange wire at a fuse link I can't seem to find. I supplied an external 7.5 A fuse to power the ECM. And the check engine light came
on and I was able to Scan the system for DTC'S.
Being there were no DTC'S I then started the engine and checked all of the parimeters to find out that everything looks normal and all systems are
working including cooling fan when reached operating Temp.
My next step is to find that (rust fuse link C J/B) if
you might have an idea where that might be that
would be helpful.
I want to thank everyone who has helped and
a special big Thanks for that last wiring Diag.
Thanks 48 chev
