I have a 1999 Sunfire that had a bad head gasket. The last time I tried to start the car to get it into my garage it cranked and cranked but would not start and then it stopped cranking and would not do anything. I was afraid the engine locked up but it did not. I pushed the car into my garage and replaced the head gasket and did a tune up on it. I checked the starter and replaced the started relay. Turn the ignition on, fuel pump runs and I have power at the starter. Still will not crank. Battery is good also. I can turn the ignition on, jump the starter out and the car starts and runs beautifully. Any idea's. Is there a fusible link that could of fried?

Well I bought and installed the new switch. Found out it was not the switch but the ignition lock cylinder itself. Is there a procedure that I need to follow to program a new cylinder with new keys? The kit looks like this

Is this something that I can do myself?

Ignition Lock Cylinder - Revised Replacement Procedure

File In Section: 02 - Steering
Bulletin No: 01-02-35-010
Date: November, 2001
SERVICE MANUAL UPDATE
Subject:
Revised Lock Cylinder Replacement
Models:
1995-2001 Chevrolet Cavalier
1995-2001 Pontiac Sunfire
This bulletin is being issued to revise the Lock Cylinder Replacement procedure in the Steering Wheel and Column sub-section of the Service Manual. Please replace the current information in the Service Manual with the following information.
The following information has been updated within SI2000. If you are using a paper version of this Service Manual, please make a reference to this bulletin on the affected page.
The following information was omitted from the Service Manual:
If you replace the ignition lock cylinder, the system will enter the long tamper mode. If the system enters the long tamper mode, ensure that the system completes a long tamper mode cycle. During the long tamper mode cycle, the THEFT indicator will flash for the full 10 minutes. The instrument cluster and the PCM require the full 10 minutes in order to complete the learn cycle. Ensure that the ignition switch remains in RUN until the indicator stops flashing. If you turn the ignition switch before the indicator stops flashing, ensure that you repeat the long tamper cycle from the beginning.
Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, even if the vehicle starts on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn

Well I got the ignition lock changed out. I go to start and it will run for 5 seconds and shut off then the theft light flashes 6 times and stays on. I leave the key in the run position for a full 10 minutes after that and still only runs for 5 seconds or so. I checked for codes and it is clear. According to the instructions the theft light is supposed to flash for ten minutes but mine don't. It just stays lit. Any ideas what I am doing wrong?
