Questionthere are no experts for chevy but this is a gm car. I have a 1986 corvette with auto trans. it will not crank with no sound from solenoid. it has a new battery. headlights and dash lights ok. I did some troubleshooting with my shop manual and located a dark green wire from the starter enable relay to the vats decoder module. when i jumper this wire to ground then turn key to start, it will start with no problem. does this mean that the relay is bad or the decoder module or the starter solenoid? does the relay ground the module or the module grounds the relay? or could I have a bad ground wire somewhere else? thanks for your help in advance, al.
AnswerHello Al,
You are really challenging my memory on this one because what I remembered in the early years on the Trans Ams, Cameros and Vettes is they did not use a starter disable and would crank and not start without the proper key, but you may be right, however, it should not be starting and running by jumping this relay if it was a Vats issue because the fuel to was shut off.
No matter what you do, go to an alarm store (they have bypass resistors and bypass that junk! It will only give you problems.
Then install at the least a hidden starter disable toggle because it is 30 seconds to defeat the left side of the column and steal it! We did over 10,000 steering column rebuilds from theft!
I would check to see if the relay is ok. Take a different relay out of the car and put it in place and see if the car starts. If so, you need a relay.
Something is wrong here though because I am wondering if the vats already is bypassed. Vats shuts off the fuel and spark, so jumping that relay would not start the engine. Switch out the relay. It costs you nothing to test.
Let me know.
