What year? If it has a CEL, does it come on when the key is turned to run like it should? When cranking, the CEL should shut off. If it stays on while cranking, the EEC is not getting a PIP signal.

Any chance the timing belt broke?

Is fuel pressure good?

cel= check engine light. Make sure everything is still turning ie. camshaft, distributor rotor. If so, it sounds like a bad TFI module to me.

Did you also replace the pick-up in the distributer? A few people replace both TFI and pick-up together just to make sure. You might also want to check to see if you have power to the TFI start connection at the harness. The colour of the wire at the TFI harness should be the same colour as the wire that goes to the starter solenoid start pole.

The next mod is to install the GN intercooler.

Not to be insulting, but start at the basics and recheck everything. One time I crossed the spark plug cables and it wouldn't start. So check all your work one more time. Then, if you've been cranking it a lot, you could also take out the plugs and dry them up, and put them back in. Again, did you replace the pick-up coil in the distributor?
