2003 Saturn Ignition and Security System Troubles

Daughters 2003 Saturn L300 has been having electrical problems. She can be driving along and suddenly the fuel gauge goes to E and the transmission begins to shift rough. If the car is turned off it will not start again. The problem is intermittent and difficult to reproduce when you want to diagnose it. The security system has also prevented the car from starting and I had to turn the ignition key to run for 10 minutes in order to get it to start, Most recently, The car cranked but would not start. I inserted the key and jiggled it and then moved the shift lever to neutral and back to park and the thing started.. I'm thinking ignition switch or PCM??? any thoughts or advise??

Sorry to say but it's probably the BCM (body control module) that's going in her car. The BCM controls everything inside your car, from the gauges, locks, daytime running lamps, ABS... and yes the security system. I have a 2003 L200 which had the same problem and I had to replace the BCM at some cost ($400-$600) depending on where you go. The L-Series Saturns seem to have a problem with their BCMs and it seems that it's pretty prevalent. Unfortunately it will only get worse as time goes on and it's not something that you can do yourself as it needs to be programmed by the dealer. You also will need to get your remotes reprogrammed as well with the new BCM. Hope this helps.

My Saturn L300 (2003) starts sometimes and doesnt others. when it does start sometimes it will just die. i have replaced the fuel pump, fuel filter,crank sensor and the transmission control module. my...


If it starts up easily when the engine is cold and has a hard time starting (or won't start) when the engine is warm a lot of times it's related to the ground cable(s). If the problem is related to the security system I would think it would be an all or nothing kind of thing (ie. it wouldn't start and then die). Another thing to check would be your fuel pressure to see if it's actually staying at the correct pressure after the car starts.

The 2003 Saturn Vue is equipped with the Passlock II system

The factory alarm can be programmed on or off using the factory remote. To turn the factory alarm on or off, turn the ignition on and
press the PANIC button 8-10 times in 5 seconds. Within 3 seconds press UNLOCK to turn off the alarm or LOCK to turn on the alarm.

2003 ion starting after running


Google Saturn Ignition Lock and you'll see that this is a major problem with these cars. I bought a 2003 Ion in May 2008 and have had it in the shop 3 times for starting problems. I just had the entire ignition lock system replaced last month and so far it's been okay. Saturn will acknowledge that this is a problem, but there is no recall or true fix for it.
