Installed new FLT automatic tranny. Installed Kooks headers, with MSD wires, and new spark plugs. (150k miles 1995 Camaro Z28 (LT1), original O2 sensors).
She starts up fine - let her idle for 5 minutes, not a heartbeat missing.
The "Check Gauges" light on the dash is on and the oil pressure, engine temp, and fuel gauges are all wacked out:
- Oil pressure - no reading or movement
- Engine temp - no reading or movement
- Fuel gauge - shows "more than full"
I've checked all their wires and they are all connected and there are no breaks. I've checked the ohms for the engine temp sensor and it is within tolerance. I've not disconnected ANY of these wires or sensors during the header and tranny swap-out.
All else works fine - Meziere electric water pump, alternator gauge reads normal, headlights, blinkers, dash lights, horn, etc all work. Engine purrs and revs nicely.
Any ideas?
