I was in the process of getting ready to service my car so I unhooked the neg. Battery post. Before I started the work I went to hook the battery post back up to start the car so I could move it. All the gauges lights up but the car won't start and the security light is flashing. Been having this starting problem on other ocassions but all I had to do was try another key and after a few minutes it will finally start. On this ocassion I have tried both keyes and the car still wont start with the security light flashing. I even disconnected the aftermarket remote starter with still no luck. When I turn the key to start, the radio and daytime running lights turn off and when I let the key go they come back on. Is there something disabling my starter? I have a 1997 chevy lumina 3.1 engine 123000 miles

Have you done a relearn on the pass-key?
GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it.
You may need to unplug the key module of the remote starter to get a good relearn, if it has one, and it probably does.

I took off the aftermarket remote start and put everything back as normal before it was put in. I tried the relearn and the light just keep flashing even after 10 minutes

1. Look into key opening and check key pellet sensing contacts in ignition key lock cylinder. If contacts are damaged, or not Silver in color, replace ignition key lock cylinder. Ensure ignition key lock cylinder wiring is properly routed and not twisted when replacing lock cylinder. Cut off wire retainer leg on original connection when replacing ignition key lock cylinder. See Fig. 2 . Using PASS-Key II(R) Interrogator (J 35628-A), check ignition keys. If key code window displays "E" for error, or display is erratic, replace key. 2. Check ignition key for cracked, dirty or coated resistor pellet. Ensure key does not have excess plastic around resistor pellet contacts. Check instrument panel fuse block fuses No. 10 (15- amp), 11 (5-amp), 12 (10-amp) and No. 39 (10-amp). See COMPONENT LOCATIONS . Check fuse contacts. If symptom is intermittent, check theft deterrent module connector is clean and tight. Ensure engine grounds are clean and tight. Also check ground wires located behind instrument panel, on right side of brake pedal bracket. 3. If theft deterrent relay must be replaced, using DVOM, check for short in Purple wire between theft deterrent relay connector terminal C1 and starter solenoid terminal "S". A short in Purple wire may cause theft deterrent relay to fail. 4. Check ignition lock cylinder key pellet sensing contacts and wires for continuity. Disconnect ignition lock cylinder 2-wire connector near base of steering column. Using ohmmeter, measure continuity in white wires between ignition lock cylinder connector terminals "A" (White/Black wire) or "B" (Purple/White wire) and key pellet sensing contacts. Turn and adjust steering wheel. If there is any change in continuity or any intermittent readings, replace lock cylinder and steering column wires that come with it. 5. Check for proper installation of aftermarket electronic equipment. On 4-speed automatic transaxle, check for proper adjustment of transaxle range switch. 6. If theft deterrent module on Special Equipment Option (SEO) vehicle must be replaced, check Pink wire (security signal) between theft deterrent module connector terminal B7 and B8 for resistance. Resistance in this circuit may cause module to program itself.
