problem

When trying to tune today, at WOT, the car went boom and killed on me. The rpm guage doesn't work on the safc or the guage cluster. The car will crank but does not spark. The T-belt is fine also unless it skipped. Could this be caused by the SAFC connection that goes to the computer coming out? Would this cause it not to start? I don't have time to look at it now because I work.
Thanks
