I have a 1998 Buick
lesabre custom, It won't start. All of the instrument panel lights are off when I turn the Key forward to crank
. they will come on as I jiggle it in the start position and the starter turns over and the car starts. But upon releasing the key it dies. I have replaced the Key Lock Cylinder with new resistance key, with the same results. Help ! The security
light is on in the brief moment the car starts and, or however long I hold the key in the run position.
lets start from the beginning. there is off, acc, run, start. Crank and start would be the same. Lights off when I turn key forward to crank tells me no lights in start. It didn't tell me lights off in run. So the lights are off in run but are on in start then?
Power into the ignition switch is the red wire from the IGN sw 60a fuse in the left maxi fuse block.
Power Out of The ignition switch has a pink wire that is supposed to be Batt+ in run, bulb test and start. It powers up fuses for injector fuse 7, pcm fuse 8, fuel pmp fuse 6, engine obd2 fuse 5, and other stuff. Check to see if power is active on that wire key in run and start. you can check it at the wire or just check it at one of the fuses.
orange wire hot in run. brown wire hot in acc, run. light blue hot in run. yellow wire hot in start. But Pink is the main one to check first.
