1998 Aurora 4.0 W/4T80E No Spark! Please Help

[Jason.H]

Hello everyone. I just bought a 1998 Aurora It had bad head gaskets. I swaped the engine out I ended up changing the whole wire harness from the original engine along with the Throttle body because the other engine was not mass air metered. To make a long story short I got everything back together now. all plugs are connected and everything seems to be in order.
But the security is tripping out in this car parking lights flash at random and a clicking under the dash coming from this box With this # 25640703 Oh yeah and I have no spark at any of the spark plugs or coils?? I cannot wrap my head around what is going on with this car. I need this car running yesterday.. Thanks much for anyone that can help with my problem or that can at least point in the right direction. (BTW I changed the lower Crank sensor and the cam sensor with no change in spark) (Ignition Modual And Coils Check out also)

I doubt that this will help but 25640703 is the daylight module turns the headlights on during the day...

Thanks I just did a search and found out what the problem is with that. Now I just need to figure out why it has no fire. This car will run engine has good compression just has no spark.. Can't Figure out why though.

Check Crank position sensors

Thanks I changed one already, I am going to change the other one tomorrow. I have all the parts from the old engine so I know they worked. Funny thing is though is this engine ran when pulled from the scrap car. So I don't really understand why it will not start in my good car...
