Id prime like 87chevy said and then probably see if it fired off. Check the exhaust with a temp gun to see if they are all heating evenly. Depending on what it shows for temp can determine what you do next. If everything heats evenly you could monitor the exhaust with a wide band, and/or monitor things with hptuners or something similar. The other option is to send the injectors to be cleaned or replaced. I would have a hard time just firing it and doing anything other than idling without some kind of monitoring or having had the injectors cleaned. Its too risky and too expensive to chance.
