2006 Pontiac Grand Prix No Start, No Spark after solenoid replacement

After replacing the pressure control solenoid and the rack and pinion on a 2006 Pontiac Grand Prix, we are failing miserably on successfully starting the car.
At first, there was no fuel pressure but we had spark. We corrected the fuel pressure but now lost all spark. We replaced spark plugs and coils, crankshaft position sensor, cleaned the throttle body, all relays and fuses are good, good battery, tested ignition control module and still nothing. It cranks but then nothing happens. Could the crankshaft relearn thing or the theft deterrent be an issue? Or what are we doing wrong??? On all the theft deterrent articles I have read, they state to look for the "Security light" on the dash. It is to my understanding that 2006 models did away with the dash light. So not too sure if it is armed or not....HELP!!! No access to a GM Scan tool anymore... :(
 


What do you mean by "We corrected the fuel pressure"....? What did you do and why did it not have fuel pressure to begin with?

Also by "tested the ignition control module" how did you test, and are you getting any spark at the coil packs?

I know one common thing to do is forget to reconnect the crankshaft position sensor wire or the ground to the icm bracket. Both run under the bracket and are fairly easy to leave off.
 
By correcting the fuel pressure, all it was was a bad relay...the ignition control module we tested thru a step by step prodecure we found online involving a volt meter...
 


Make sure your ignition relay is fully seated. If it is swap it out with the headlight relay and see if it starts. Like 5FDP said do a security relearn regardless. If that doesn't work check the connection pins at the ICM harness and be sure none of them are bent or pushed out of the harness. If none of this works look for a ground or connection left loose.
