    It's best to follow trouble shooting procedures found in the workshop manual to check for mechanical integrity (able to develop compression, components in synchronization ect..... ) and check for spark and fuel system integrity. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info. There is also a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online

    Do you have injector pulse? If you have injector pulse, spark, and fuel pressure, next I would check to see if mechanical timing is off, maybe was set few teeth off incorrectly during rebuild. Hope this helps.
