sounds like you may have a connection problem. you should have your ignition switch circuits checked.

there is two red wires that bring battery voltage to the ignition switch. One comes from ing switch fuse the other one is from ign switch accessory fuse.

If they both check out good then check the output from the ignition switch. Yellow is the color for the starter enable relay. Orange is the color for the wire that supplies power to the instrument panel fuse block. at the ignition switch connector the light blue wire goes to power up the instrument cluster via IGN OFF/UNLOCK fuse 3E in the instrument panel fuse block.

See what is happening on these wires and let me know what you find out

thank you for your reply and patience to allow me time to test this. I am assuming that the ignition wires are of a heavier gauge than most other wires (IE 12 gauge instead of 14).
There is a RED wire that is hot. Then a Red with white stripe that is hot. Turning the key on to RUN, makes the orange wire HOT (but no gauge response or dash instrument lights) and the yellow is COLD. Turning the key to start (engage the stater) the yellow wire then goes HOT. There is not a blue wire nor is there a fuse in 3E.
I think that, by these tests, the ignition switch seems OK and the issue must be elsewhere. Other suggestions? Is there another fuse box behind the glove box that should have fuses checked? I have checked the under dash fuses and the fuse/relay center under the hood and all fuses test OK.

Could this be a resistor issue with the keys? I have tried both keys and neither worked.

Thank you in advance for any additional assistance you can provide.

there are 3 fuses for the cluster.

fuse 1D (15A) In the left side dash fuse panel (hot with key on)

fuse 9C (10A) In the left side dash fuse panel (hot all the time)

fuse 8 (10A) In the right side dash fuse panel (hot with key on)

if the yellow wire for the starter is working at the ignition switch then it goes to the starter enable relay. That relay is connected and controlled by the passkey II decoder. But that shouldn't affect your dash. Check fuse #4 in the under hood fuse box for power. It is the fuse for the passlock.

If you could get a scanner that has the passkey information in it you could see if the information from the key is working. (tech2) check for passkey codes.

Again, thank you for your prompt response.
Fuse 1D COLD with key in any position
Fuse 9C HOT all the time
Fuse 8 (not sure which 10A fuse is #8) but there are only (2) 10A fuses on that fuse block. BOTH are COLD with key in any position.

I have a scanner tool for the 1998 and below vehicles and the scanner will not connect. Says vehicle not found. It appears that there is something that is causing the cluster not to power up AND the starter/circuitry not to activate. PCM?

Also, all under hood fuses are HOT on both sides all the time.

if the fuses that are supposed to be hot in the run position do not show battery voltage when the key is in the run position then I would suspect a bad ignition switch if the powers going into the switch are all good.

If you have a fused jumper, you could use that to supply power to the 1D fuse and see if that lights up the circuits on that leg of the ignition switch. be careful not to overload any circuits.

So, I put in a jumper from battery + to fuse 1D and the dash lights came on. Turning key to start position and car started. Based on this, does that confirm your suspicion of bad ignition switch?
If so, do I replace the key and lock portion or just the wiring harness to it? Online pics show key with lock and resistor wiring and others show a harness.

Thank you again for all your expert assistance. It appears that you have helped me get to the root of the problem.

yes, it sounds like the ignition switch is the problem from what you have found out. The ignition switch is different from the ignition lock and tumbler. You don't need to do anything with the lock and tumbler section. you ignition switch should look like the picture on the first page.
