Okay - So I have a 91 RS Camaro - and it wont start. When you turn the key everything in the engine comes on - but it wont turn over. I'm almost positive it's the resistors and the VAC that's not letting me start the car.

I read the review on how to bypass the VAC - although I am not able to find a "pair of two yellow wires" coming out of my steering column.

Could someone help me locate the wires and connector so that I could get my car running? Could they possibly be different colors?

Thanks!

 

Heres a pic

Only yellow wrapped wire I see goes to the airbag...

any suggestions?

 

Here is a picture of the wires that you are looking for. On the early models it was two yellow wires with a black heat shrink wrap coming down the steering column. On later models it will be two white wires with a orange heat shrink wrap on them.

 

Looks like the orange covered wires in the center or your pic.

 

Thanks for the reply. I was gone on vacation to New York and came back to this mess. But your information was very helpful. I have now located the wires and disconnected the plug.

After testing the key on (Ohms X 1K) it registred as 3 which I'm guessing is 3000 ohms.

After a trip to Radio Shack I bought a 3.3 K Resistor and a 330 Ohms Resistor just incase it wasnt the right one. I've tried both and neither work.

Shouldnt I be able just to touch the two wires to the resistor and the car will start.

This HAS to be the problem but something isnt right.

When I checked to see if the resistance was changing when the key turns - I got absolutely nothing at all under the dash. It just stayed at 0. Shouldnt I be able to pick up something when the key is at the off position and when it changes also?

Any help would be greatly appreciated. Thanks again Trickster...

This has all the vats resistance and acceptable ranges. 3300 ohms is close enough. You need a 3000 ohm resistor. If you have two keys you should be able to touch the wires to one of them and start it with the other.

You should be able to measure the resistance of the key at the wires at the base of the column with the key in the cylinder. If it's an open loop, the wires are broke. The resistance should not be zero.

 

Well hang on a sec..

I dont have two keys. Just one ignition key that reads exactly 3000 ohms.

Radio Shack only as a 3.3 k ohms (3300) Resistor.

I guess I am confused on what I need to test. The wires coming outof the column (orange wrapped) or the other wires going into the dash?

Where do I put the resistor? Will 3300 work if my key read 3000?

Would pictures help?

Thanks....

 

You would connect the resistor to the connector that the wire from the steering column goes into. Do not connect them to the wires from the steering column.

 

HEre is the key

 

These are the wires. I cannot get a ohms reading on any of them. Even with the key in out on or off. No Reading at all...

 

This is the resitor(s) I bought

 

I was reading the vats manual lo-tec sent me. (very helpful) and it says the exceptable ranges for a (3010 pellet) Which I suppose would be me is (2890 - 3150)

Being that I have a 3300 - does this mean the resistor could be the problem?

Another run to radio shack. Be back in 15 minutes.

 

I cant find one of these daggon resistors to match my key. I've been using the ohms adjust dial on the tester to get the exact reading so when I went back and re-tested my key. I actually have a 4 ohms key or maybe a 3.9?

Still I cant seem to find a resistor that will comply!

I'm lost - Any help would be really great....

And thanks thus far...

 

Two options, buy another key and solder it in or find a different electronics store that carries that resistor. Radio shack has a large kit listed online that includes a 3k resistor. Part# 271-312. I would check the yellow pages and call around.

 

just pararrel the 300ohm resistor with the 3300ohm resistor and you get........bingo.....3000ohms!

 

Hahahhahaha nice try. Oh, you were serious?

Try 275 ohms.

 

P.S. 3.3K with a 33K in parallel is what you want for 3K ohm exactly, but the tolerances on those resistors aren't too exact, try metal film resistors if you can find them.

 

How 'bout just buyin a 3K ohm resistor? This should not be that hard to bypass, now should it?????

 

3K isn't a standard value. It sucks trying to buy one resistor online as well, since most local stores will never carry that size. Not to mention shipping will be literally 100X the cost of the resistor.

 

couldn't you just buy a variable resisitor and set it to the right value? Then superglue the variable resistor so it will stay at that value. This might not be the best idea but thought i'd throw it out there

1.5K should be a standard value at your local radio shack, just put two of them in series. Their tolerances might not be the best either, but it might work. There should be other combos that work too to get your 3000 ohms.

R1=Resistor #1, R2 = Resistor #2, RX = Resistor X

Total Resistance in series = R1 + R2 + RX
Total Resistance in parallel = 1/(1/R1 + 1/R2 + 1/RX)

Total Resistance for only 2 resistors in parallel =
(R1 x R2)/(R1+R2)

 

The other possibility is that the lock cylinder leaf contacts are damaged, dirty, or disconnected.
