Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
yes I read what you have done.
Got a couple of questions.
So what scanner are you using for this job ?
Also did the problem start after the clutch job or are you aware of it being bad before ?
I want to figure out which of the computer data lines doesnt work when the car doesnt start...
I feel the same way, the cluster is the most likely faillure. Try to get a used on at the junk yard to test. Also try the following: Get the schematic for the computer data lines. Then disconnect the modules in the different data lines one by one to see if one of them is interrupting the communications. You can have the solus on there and each time you disconnect something then try and communicate with the ecm. This is what I normally do to catch these types of issues. Also as long as you are disconnecting the computers go ahead and do a thorough check of the wiring that is close to them. I did hava a cadillac cts that had bad wiring under the front passenger seat and when they mpved the seat a bit it would ground out the gmlan and the thing had to be towed...
any luck with this ?
