TBI to TPI now no injector pulse HELP!!!!

I pulled out my TPI 305 from my 91 Z28 and transplanted it into an S10. The S10 was originaly TBI so I followed the TBI-TPI swap tech article. I swapped it over to a 730 ecm and I am using the same memcal I had in the Z. I am good at wiring and I took my time changing pins. I even double checked every pin after I swapped. It is all hooked up now and all I get out of it is spark, no fuel injector pulse. When I check the voltage at each injector plug I get battery voltage on both sides when the key is on. I have disabled VATS in the chip so that is not an issue, I have checked all the fuses and they are good, grounds look cool too. I manually gounded the injectors and the thing ran. I am out of ideas. Maybe someone here is thinking of something I am not.
