5.7 Hemi Swap Tech question

I went through my wireing and tested alot on my computer tonight. I have power going everywhere there is suppose to be power, and grounds everywhere there is suppose to be grounds, on run and start mode. I have a signal from my crank and a signal from my cam. Getting oil pressure signal. The codes it is setting is , low volt IAC , Intake air temp, o2 sensor down steam( which im not useing), battery temp, a/c comp, fuel level, once in awhile a oil psi code will pop up while cranking, but i have a manual ga and it has plenty while cranking. I dont think any of those would keep it from fireing the injectors. I checked my ASD relay and its working properly. Im starting to think that something isnt programed right in my computer. THis is a special computer I bought so I could run my 727 tranny. The company that I got this from will not return email or phone calls from me. so thats out of the question. Any other advise? Thanks!!
