My 95 Chev. classic won't start. The pass key fault light won't go off. only way the car will start is that to touch the starter and it will start. but will shut off in a second. every thing is good. It like it has a kill switch,

If the truck runs, I would say its a bulb.
If the truck won't start, look at the fuse for the ECM.

Get a second ignition key, the one you are using is dirty or moisted, you need to turn on and off the car witha clean key, hapens to me once in a while.!!

did you get a new key made without the chip? The car will not run without the chip in the key. Could be a bad chip in the key itself. Get a replacement where they sell keys with a key chip identifier.

you will need to replace the ignition switch. the wires running from switch have broken very small wires. common problem.so it is not seeing the key chip and causing security to go in theft mode

My light stays on

Make sure battery is fully charged. If so you may have a shorted starter, and it will nedd to be replaced.

i had the same prob in my 94 the ignition cylinder is bad change the ignition and i swear it will work perfect

Put the key in turn it on don't start it wait 10mins turn the key off remove it waits 10 seconds repeat this 3 times this should help if not try this with another key if it still don't work your ignition switch ifs probably bad dealer must replace and reprogram new keys. I got this info from the emission wiz it helped me on 2 different cars

WELL I HAD THE SAME PROB. ON A 95 CHEVY CAPRICE.I REMOVED THE IGNITION AND THE WIRE WAS BROKE.WHEN U TURN THE KEY THE PASS KEY WIRE TURNS WITH THE IGNITION,WHAT A FAULTY DESIGN.ANY HOW BUY A NEW IGNITION AND KEY THAT SHOULD SOLVE THE PROB. GOOD LUCK

If the car starts and dies right away you may have a pass key sensor fault.
Try to start the car,if the car dies right away just leave the key on and watch the security light in the insturment panel,if it begins to blink leave the key on until it stops blinking (apx 10 mins.) this will reprogram the pass lock to the pcm and may solve all your problems.if the car continues to die after running a min or so then you may have other faults,or if the car dies right after start the pass lock sensor may need to be replaced.
