No fire to spark plugs

[monkeyy337]

I'm trying to help out a friend who just changer over his 85 hot air car to a inter cooled system. The problem is there is no spark at the spark plugs so of course the motor will not fire. Just to explain what has been done/checked so for:
1. A new motor was installed.
2. The computer and wiring harness have been changed to a 87 GN configuration.
3. The crank senson has been changed 3 times
4. There is current down to the crank sensor
5. There is fuel pressure.
6. The engine turns over fine but will not fire, no spark at the plugs.
7. Engine and other item ground wires are installed and tight.
I realize I'm not give you guys much information to go on but thought maybe someone out there might have some ideas. The car was up and running with the hot air motor Monday so the car has not been setting very long. Any ideas would be appreciated.

Is the igniton coil connection tight?
Is the connection at the ecm tight with chip inserted?
Take off the cam sensor cap and see if it is turning.
Any codes?
Do other electrical items like horn and lights work?
Is the ecu plug near the battery connected?

ignition fuse (at fuse box).

Checked the fuse twice, its good. One other item that I forgot to include, the master cylinder was also changed over to a power master and this car has an after market auto start installed in it. The guy that installed the auto start system will be here in a few minutes to check his system out.

Had the auto start system checked out and there is no problem with it, back to square one.

Any more suggestions?

Go back to the basics. Tedious, but it works.
