If you need a how to on bypassing the clutch switch I can post it when I get home from work tonight.

Re: Intermittent DNS
 

You are correct. I am on the road in Colorado right now and wasn't following you comments carefully enough. I suggest troubleshooting the starter circuit to identify a switch or wiring that is failing. I don't have any manuals with me so I will leave the explanation to others.

Bypassing the switch is easy. Pull the hush panel and look up under the dash and look for the 10 gauge PURPLE WIRE plug,it should be towards left of the steering column. I have a jumper I made,if you were closer I'd loan it to you for some trouble shooting.

Jumper across the plug then?

Might not be much use but I posted my experience here :

Check out post #53 I posted a photo of the clutch switch on my 94. Just thought I would add that because I jumpered the wrong switch early and chased my tail for a while before I realized it.

Re: Intermittent DNS
 

Yes. I've got a new switch but when the time comes to replace it I'll bypass it,too much of a hassle to get to the switch.

Re: Intermittent DNS
 

So a couple weeks ago I had the DNS again. I replaced the battery and ran a bypass on the clutch safety switch and thought I had solved the problem. WRONG!!

This morning when I got in the car to go to a show I turned the key and no crank. I tried jumping it on both my pickup and a battery charger, waiting 5-10 minutes between each attempt. Then I ran a jumper between the purple wire and the VATS lockout relay. It will crank but will not fire. I have fuel pressure in the rails, plenty of voltage at the battery, but I dont know if the injectors are firing or if I have spark. When I crank it the tach needle comes off its stop but only shows 0.

it is difficult alot of times to turn the key cylinder back so I can get my key out.
Help!!! This is my dream car, but I've never had a car this unreliable.

Anyone??

Pull a spark plug wire then crank it with a plug checker or just a screwdriver to ground and see it you have spark. If no spark I'll bet it's a VATS issue.

One other option is to put a secondary relay in for the starter,check out sticky thread in the ZR-1 second on the other site.
