Injectors not spraying like they should

[Trav15]

Sunday after noon i removed my radiator, and turbo setup to give me enough room to drill and tap my head to heilo coil my exhaust manifold studs. Put all that back together. Took out my 680 injectors and put in fic 1050s, brand new seals. Put bolted the fuel rail back down set dead time to 330 and global to -61 with link. Went to start the car it would crank and crank. Start for second, sound like complete *hit then then die. I got it started and kept it running with the throttle and it was running lean the entire time. The cyl #2 runner on my manifold was significantly cooler in temp than the rest. So i pulled the fuel rail and set it on my valve cover to see if the injectors were all spraying. They were all spraying but not very much at all. So put my 680s back in, same result, barley spraying. So i put my friends 750s in, same result. Im lost, no idea what to do next. Injector pack maybe? Are my settings right? any input would be great!! Thanks

A log would be helpful...
Injector deadtime should be set after the car has been started and watching your CombinedFT values to get them to 0% (+/- 2). I know its early as hell so your probably not going to be running out to your DSM right now but if the injectors are installed ZERO your deadtime and set your global for the injectors that are in there, then play with deadtimes starting from 0 to adjust the CombinedFT.

alright i will have to put the 1050s back in and give that a try. It might be a few days between work and being finals week my schedule is pretty full.. But i will try that asap

The deadtime adjustment directly effects the pulse width of your injector, thus if set incorrectly could totally create the problem you described.
