Dead Gauges/Odometer no start... Ok, here's the break down...
Car had been driven all day in rain. Had time to dry out before rewashing. On the way out the gas peddle went hard. Had to shut down and restart. Gas peddle worked fine again. The car had not gotten wet again before the gauges died. continued through the wash and shut it down. No gauges, odometer & no turn over. Had the fog lamps on when this happened, left turn signal stayed on the dash when this happened. Turned lights off, turn signal goes off on dash. No Security Light's staying on. Radio, windows, wipers, seats, dome lights etc still work.
1. Battery tested good.
2. Starter tested good. (Replaced as it was off car and original one)
3. Alternator tested good.
4. Traced wires to all with good voltage.
5. No voltage to "exciter wire" on starter when key turned.
6. PCM pulled but not sure why... Now put back in.
7. Grounded PCM... No change
Recent upgrades or maintenance.
1. Replaced sockets for RF DRL and LR Side Marker. (Soldered new ones on)
2. Deleted EGR
3. Deleted AIR Pump
4. LTH (Deleted CAT's)
5. ORY
6. SLP LM 2
7. Wide band O2 (Also doesn't work)
8. Outer tie rod ends
The car has been dyno'd and EGR & AIR Pump Deleted from the PCM. The timing and spark had been advanced to lean out the AFR. I have driven the car at least 3k since these changes and have not had a problem occur after the changes until now.
None of these upgrades, changes or maintenance would seem to be reason for the dash and odometer, air/fuel gauge (added) and no signal to the starter to occur.
Question 1: Would the ignition switch (located under dash on stearin column) were to go bad, would that also control the dash and odometer to also not work?
Question 2: If I can get the starter to spin and start the engine using a different battery to start the car running, and the gauges don't work, would it be safe to say that it's the ignition (Depending on the answer to question 1). Or would that mean it's the PCM or BCM?

Did you check your fuses? I had a similar problem with the gauges not working and the car not starting up. Turned out to be a blown fuse.
