1999 Grand am 3.4 v6 Starts and then dies immediately (need help))

Spraying starting fluid did not help me still same issue, and I checked fuel pressure 3 times and it seem to 42 psi which is normal, but before all of this even happened, I put in a new engine and I had it running without doing any security procedure and it ran for 30 mins and I was doing the process of bleeding coolant... While bleeding coolant the car just shut off and it wouldn't start any more it would just crank but not start as if it wasn't getting any spark , I found that the wire going from my crank sensor to my icm and it seemed burnt so I replaced the crank sensor and icm and also the wire connecting both, and now my car starts and shuts off after 2 seconds.. In other words I really don't think this would be an security issue since I had the car running before with out the procedure and have the system disabled, but I do notice a solid security light, it's not blinking at all

Yeaa I tried that method , but the thing is that the security procedure will only work if my security light is blinking , but it's not it's a solid security light

Any suggestions?

Possibly the ignition switch. The sad thing is, it's really easy to replace in a 1978 ford, but it might get complicated with the security system that exists in your pontiac. Can only suggest the cause at this point, sorry can't help further.
