I have spent numerous hours trying to resolve the same issues. Much time was spent searching the internet for clues as well. In the end, I bypassed the anti-theft system and have left it in the "off" position. (Example site) I had followed many other paths before my warranty ran out (ex. replaced ignition cylinder) Time will tell if this is the solution. I had not yet replaced the fuel pump as many other folks did (and for them the problem came back)

This may be related to the antitheft system The system is known for turning off the starter and/or injectors when it fails. Is there a light on the dash that says SECURITY? This is a common problem worth looking into.

How to reset anti-theft on a 2000 alero


The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

I need all the diffeent firing order for gm 3400 2000 I have a back firing issue that won't let the van start?


it sounds more like the crank sensor is bad. when crank sensor has failed or is failing, certain timing problems will arise. the engine may start but shut off in a few minutes or seconds of operation. more than likely engine will not start. it controls timing, engine backfire, no spark or pulse at injectors, car will stall when stopped. heres the firing order: 2-4-6 front from left to right
1-3-5 rear left to right hope this helps !! go here for a diagram-- http://autorepair.about.com/library/firing_orders/bl-fo-6417.htm have a very good day !!

Security light not on, engine won't crank


Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.
