86 won't turn over or start

OK, gang, I need your help again. My 86 coupe automatic won't turn over unless I jump the hot lead from the battery to the starter to the switch circuit.

When I turn on the key, I can hear the fuel pump energized to injectors and the dash lights dim a little, but no click or any sound from the starter.

I've tried all the door keys in the door lock stuff and waiting 10 minutes, etc. and no go. So, I've narrowed down to neutral safety switch or VATS. I'm leaving for a big event tomorrow, so I need to get this fixed like right now.

It was working just fine a couple hours before it started this problem.

When you hot wire from the battery to the starter does it turn over a t anormal speed or is it a little slow? Is the battery FULLY charged? There might be enough juice to run the pump and a few accessories but not crank the starter. If the battery is fully charged, when you hot wire from thebattery to the starter and the starter spins, will the engine fire with the key on? If it doesn't run, are you getting spark at the plugs?

Just a few questions to get us started

I didn't really have it turning over. I was just checking to see if it was something besides the connections. When I turn the key to start no sound comes from the starter but when I jump it, it starts to turn. I could go out and run it back on the lift and see if I can start it that way and get back to you.

Remember, it was working very well just a couple hours before. I know a battery can do strange things all of a sudden. I'll try starting it on the lift using a jump.

OK, I jumped the starter with the key on and it turned over very well and started right up.

But, after I shut off the engine and tried to start it again no turning over as before.

I'm thinking Neutral safety switch or VATS. If it's vATs I don't have time to get a bypass shipped to me. Any way to bypass without the kits?

don't know if this helps but on my car when it did the same thing i had to crawl up under the car with it sitting on the ground (i was at Wal-Mart) and hit the starter with something. i used a roof tach hammer.( a carpenter stopped to see if he could help). and she started right up.. but eventually had to replace starter.

maybe this helps just try lightly-moderatly hiting the starter and see if helps..

No, it isn't the starter. It works fine when jumped from the hot side to the switch circuit.

Could still be the starter solenoid. Are you getting BAT+ to the Starter Solenoid with IGN to START?

If so, probably the solenoid. If not, probably the VATS/NSS.

Now, if I energize the solenoid by jumping the hot lead to the end of the solenoid and it works, wouldn't that indicate that the solenoid is ok?

I can start the car using a jumper to the solenoid.

Nope.. that's exactly how to get around a bad solenoid.

Well, I tried putting a new Neutral Safety switch to no avail. Perhaps we are looking at VATS or a bad solenoid. I have an aftermarket mini starter on the car.

I still need to know how to disable VATS. Wouldn't VATS shut down fuel if it was activated? The reason I ask, is that I can start the car jumping the hot to the switch lead on the starter. If vATS shuts down fuel, that wouldn't work. Help please!!

Well, I checked voltage at the ignition side of the starter and there is none when the ignition is keyed to start. It looks like VATS or maybe even a bad ignition switch???

ALL 1986 TO 1988 CHEVROLET CORVETTE MODELS.

Fix it Now:
Head to a Radio Shack with your key. Have them measure the resistance between the metal contacts on the side of your key. Then buy a resistor of the same value (1/4 watt).

Remove the D/S hush panel (under the steering column).
Disconnect C281 at the 2 way connector (base of steering column) with two black wires in the female end and one yellow and one brown wire in the male end.

Connect the resistor into the male end of the C281 connector (crimp 2 female pins to the resistor legs).

Do I understand correctly that I'm going to put the resistor between the two male ends of the wire and connect the two female wires together?

Will this procedure bypass my VATS? I hope so as this is primarily a race car anymore.

Do I need any other electrical supplies?

I put my tester on the key and came up with 402 ohms. So that is a number 1, correct? So, do I buy a 402 ohm resistor (1/4 watt)?

OK, I looked under the steering column. There are a bunch of wires down there. There is one 2 wire connector with 2 yellow on the male sice and a brown and yellow on the female side. These are tiny wires. I didn't see any other 2-wire connectors. A little help here would be appreciated as there is a HUGE clump of wires connected to the base of the steering column.

Best I can do 'ya is a '90:



Steer VERY clear of the SIR connector (CKT 270).

And I don't have a '86 schematic to verify the wiring colors. Sorry.
