2002 Saturn SL2 starts for 1 sec. Then dies

First of all thank you very much for your donation.I have posted the passlock relearn instructions for you please follow them and let me know if your car starts.

Is your security light flashing on the dash when it doesn't start?Also what year and model car is the engine you got the engine for your car out of?What year and model car did the computer you changed come out of?Why did you change the steering column?So when you changed the steering column
and you said you used the old chip you just reused the old ignition housing or you did something else?Let me know.

So did all this no start stuff start when you changed the engine or before?Your not suspose to change just the chip it comes with the ignition housing you could have damaged the chip or not got it in correctly. It sounds to me with the security light flashing that you have a security issue. When you put your old computer back in did you try the relearn I posted again?If not try it again. Let me know what you find.

Here is the wire diagram for the security system and the security system operation explained.As you can read when the security system is engaged it shuts the injectors off thats why your car starts when you prime it.With your security light flashing this is what has to be happening explains everything you have decribed to me.Problem is we cant get the codes your car is setting so we can follow the trouble tree.The codes are stored in your body control module most scanners like the store bought ones dont read body codes.Also when you get the code you need that same scanner to read your passlock sensor voltage so you can trace the problem down.What i think might have happen is when you changed just the chip aka the passlock sensor you damaged it your suppose to just change the whole ignition housing not just the passlock sensor.When i say the whole ignition housing i mean where the ignition cylinder goes into and turns the ignition switch.Thats really the only thing that makes sense to me unless theres something you did when you changed everything i cant see.What you should have done when you changed the steering column was just have left that passlock sensor alone and used the igntion housing that came with the column.Then learned that new passlock.

Thats what were here for glad to hear you got it started from what you described thats the only thing I could think of that was keeping the car from starting. Thanks again for your donation and future donation. Also thank you for using 2carpros.
