Theft light on indicates a problem with passlock. You have a problem with the key or ignition switch. When I worked I replaced a lot of ignition switches, so i would say that would be your problem.

Give this a try it might work for you........
When you put the key in ignition, turn it on (not to crank) dos the security light start flashing? If so, you need to either wait 15 minutes or wait with the key on until it stops flashing. Once it stops flashing, try to start again. You should get to try it 2 times before the passlock will lock up again.

My yukon 2003 has a passlock faillure

That's not passlock. Unless you didn't state what is happening. Security will start the engine and shut in down in 2 seconds. If it doesn't crank over, check the fuse. Start/crank fuse.

Truck engine shuts down while driving. Sometimes it just hesitates and comes back sometimes it dies.

My 2003 yukon died but was low on fuel

If the engine does not crank, I doubt it has anything to do with the fuel system. You would need to find out if you have power at the starter posts when the key is in start position. Will it crank in neutral, and is the security light flashing ?

2002 yukon denali xl wont start

Does the starter crank the engine over? If so, check for spark on a spark plug wire when cranking. If you have a strong blue spark, ignition is probably good. Check fuel pressure. Do you hear the fuel pump turn on for 2 seconds when turning key to on?

2003 gmc yukon xl just dies when driving down road let it set and it will start again ........

It could be numerous things, but one particular problem I have seen with a lot of vehicles is the Crank Shaft Position Sensor. The sensor reads off revolutions as the engine rotates, If the sensor don't read where the crank is at, this will cause the car to shut down. Usually the sensor is going bad if this is the problem, once it gets worse the car will not start at all because it won't read where the crank is at period. I'm not saying 100% this is the problem but worth looking into. This is something you can do and don't take long to replace. I'm thinking the part is around $65, also if you plan on doing this yourself buy a Haynes repair manual. These explain and show you how to do a lot of work yourself better than some can explain. Good Luck.
