Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
HelloCustomer just to clarify, when you turn the key does the engine crank over?
Your JA Expert,
Ok, here is a diagram of the starting system. I'd like you to check for power at the Dark green wire at the neutral safety switch and the purple wire at the neutral safety. Let me know. It's after midnight here, so I'll be online for about 30 minutes more. If I don't respond, I'll check first thing in the morning and we can continue tomorrow. Let me know what you find.
Can you double check the readings. The dark green/white wire going to the neutral safety switch gets power through the starter enable relay. That wire passes through the neutral safety and out the purple wire. For the purple wire to get power, the Dark Green/white wire has to have power or there would be no supply voltage to that purple wire. Let's recheck that if you can.
6 terminals on plug pur no grn\wht no grn no blue yes red\blk no blk\wht no
blue live with key on all others dead with key on or start
6 wire plug goes to neutral switch no other wires or plug near by do not know what you mean
Let's do this a different way. Go to the starter enable relay. Below is it's location. Look for the following. Power on both yellow wires, when you turn the car to crank, Ground on the Dark Green wire and power on the Dark Green w/white wire. All of this when you turn the car to crank. Let me know what you find.
both yellow wires hot, key on and start.no power to others key on or start
Is the neutral safety plugged in? If not plug it in and try it again
The car did not just stop running, I have put a new engine in ....Have to get up and go to work. I will get back with you on Sunday. Thanks for your help
Do I need to pay with each reply or do I wait for the problem to be solved?
Ok, then, the car had no issues before the engine swap? That info does help. Next we certainly can continue on Sunday and finally you can pay whenever you are ready to, if you choose to, you only need to do it once. I'm with you until we fix this car, and we will fix it, don't worry. Logic always prevails. Just hit me up, when you are ready, and we'll pickup there.
Sounds Good, wish you lived in Dallas

I removed the neutral safety switch at the plug when testing for power only way to test purple for volts
Ok, now I want you to take a pair of jumper cables and connect one side of one of the cables to battery ground, then take the other side of that same set and connect it to the starter body or starter bolt. Then with our jumped wires still connected, see if when you turn the key to crank the starter engages. Let me know, I'm home and online now.
