Problem After Installing SilverStar Headlights

Not knowing much about vehicles, but an avid do yourselfer...this problem comes after I decided to install silverstar headlights in my 1997 blazer. I was replacing 9005 with the 9005 type lights. However after installing them, I noticed that they didn't work. So I placed the orginals in and they didn't work afterwards. My initial thought was that perhaps a fuse has blown. I didn't know which fuse was the correct one for the headlights, so I pulled them all out and did continuity checks on them. After placing them back in, I have a new problem. The truck won't start. Seems to just makes a clicking sound and interior lights go from bright to dim...to off after a number of tries. Another problem is that I'm stuck in the drive way. Thus I can't push it out to try a jumbstart.

So my question is, what can I do to: start this truck? or get it out of park? and then fix the headlight problem?

Is your security light flashing on and off. I so, it's in theft tamper mode.
Try this.
SYSTEM CHECK
1) Turn ignition switch to RUN position. If SECURITY light
illuminates for 3 seconds, then turns off, go to step 4). If SECURITY
light does not illuminate for 3 seconds, then turn off, go to next
step.
2) If SECURITY light flashes, go to step 15). If light is not
flashing, go to next step.
3) Turn ignition switch to START position. If engine starts,
go to step 15). If engine does not start, go to SYSTEM TESTS.
4) Turn ignition switch to START position. If engine starts,
go to next step. If engine does not start, go to step 8).
5) If SECURITY light is on, or customer reports light is on
during normal driving conditions, go to next step. If light is not
illuminated while engine is running, system is normal.
6) Using a scan tool, attempt to communicate with vehicle. If
communication exists, go to next step. If communication does not go to step 17).
7) Check for current Passlock(TM) or powertrain DTCs. If any
DTCs exist, diagnose and repair problem. For powertrain DTCs, see
appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE. For
Passlock(TM) DTCs, see DIAGNOSTIC TESTS. If no DTCs exist, diagnose
and repair instrument cluster. See appropriate wiring diagram in
ANALOG INSTRUMENT PANELS - BLAZER, BRAVADA, ENVOY, JIMMY, SONOMA & S10
PICKUP article.
8) If SECURITY indicator is off, go to next step. If SECURITY
indicator is illuminated, go to step 12).
9) If engine cranked normally, go to next step. If engine did
not crank normally, go to step 11).
10) Check fuel delivery. See appropriate BASIC DIAGNOSTIC
PROCEDURES article in ENGINE PERFORMANCE.
11) Check starting system. See appropriate STARTERS article
in STARTING & CHARGING SYSTEMS.
12) If SECURITY indicator is on steady, go to next step. If
SECURITY indicator is not on steady, go to step 15).
13) Check for current Passlock(TM) DTCs. If no DTCs exist go
to next step. If any DTCs exist, go to applicable test under
DIAGNOSTIC TESTS.
14) Diagnose and repair instrument cluster. See appropriate
wiring diagram in ANALOG INSTRUMENT PANELS - BLAZER, BRAVADA, ENVOY,
JIMMY, SONOMA & S10 PICKUP article. After repair, go to step 18).
15) Check for current Passlock(TM) or powertrain DTCs. If any
DTCs exist, diagnose and repair problem. For powertrain DTCs, see
appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE. For
Passlock(TM) DTCs, see DIAGNOSTIC TESTS. If no DTCs exist, diagnose
and repair instrument cluster. See appropriate wiring diagram in
ANALOG INSTRUMENT PANELS - BLAZER, BRAVADA, ENVOY, JIMMY, SONOMA & S10
PICKUP article.
16) Using scan tool, check for current Passlock(TM) DTCs in
TBC. If communication does not exist, go to next step. If any DTCs
exist, go to applicable test under DIAGNOSTIC TESTS.
17) Repair Class 2 serial data line communications. See
appropriate wiring diagram in DATA LINK CONNECTORS article in WIRING
DIAGRAMS. Go to next step.
18) Clear DTCs. Go to SYSTEM TEST.
SYSTEM TEST
1) Ensure system check has been performed. See SYSTEM CHECK.
After performing system check, go to next step.
2) Connect scan tool. Turn ignition on. Using scan tool,
check Ignition 1 input. Ignition 1 should be ACTIVE. Check Passlock
state. Passlock state should be Normal Decision. Check battery, fuses
and power to TBC module (Ignition 1 and power). Repair as necessary.
If repair was needed, go to step 14). If no repair was needed, go to
next step.
3) Using scan tool, check battery voltage. If voltage reading
is more than 8 volts, go to next step. If voltage reading is 8 volts
or less, repair power supply as necessary.
4) Turn ignition switch to START position. If engine cranks
fast enough to start, go to step 6). If engine does not crank fast
enough to start, go to next step.
5) Check starting system. See appropriate STARTERS article in
STARTING & CHARGING SYSTEMS.
6) Check resistance between ground and TBC module connector
C1 terminals A1 and B1. If resistance is more than 25 ohms, go to next
step. If resistance is 25 ohms or less, go to step 8).
7) Repair ground circuits. After repairs, go to step 14).
8) Using scan tool, check for communication to TBC. If
communication does not exist, go to next step. If communication
exists, go to step 10).
9) Repair Class 2 serial data line communications. See
appropriate wiring diagram in DATA LINK CONNECTORS article in WIRING
DIAGRAMS. Go to step 14).
10) Check for current DTCs. If no DTCs exist, go to next
step. If any DTCs exist, go to applicable test under DIAGNOSTIC TESTS.
11) Using scan tool, verify PCM/VCM is receiving password
from TBC. If PCM/VCM is receiving password, go to appropriate SELFDIAGNOSTICS
article in ENGINE PERFORMANCE. If PCM/VCM is not receiving
password, go to next step.
12) Reprogram TBC. Perform learn procedure. See PROGRAMMING.
Verify PCM/VCM is receiving password from TBC. Turn ignition switch to
START position. If engine starts, go to step 14). If engine does not
start, go to next step.
13) Replace TBC. Reprogram TBC. Perform learn procedure. See
PROGRAMMING. Go to next step.
14) Clear DTCs. Perform system check. See SYSTEM CHECK.
SELF-DIAGNOSTIC SYSTEM
Ensure all components are connected. Turn ignition switch to
RUN position (engine off). Connect scan tool. Check if scan tool
communicates with Vehicle Control Module (VCM/PCM). Check for
Passlock(TM) DTCs. See DIAGNOSTIC TROUBLE CODE (DTC) DEFINITIONS
table. See DIAGNOSTIC TESTS.
DIAGNOSTIC TROUBLE CODE (DTC) DEFINITIONS

All you should have to do to get it out of park is to turn the key one click forward to the acc circuit then the steering wheel should be unlocked and you should be able to shift it out of park. It sounds like your battery could be dead. If it just makes a clicking noise when you try to start it and the light dim then die, it sound like your battery. Hopefully thats all it is is your battery. Good luck.
