Vacume Prob?

Had fuel pump replaced on my 94 S-15 Jimmy. On way home found Cruise control wasn't working. Just now found out that 4x4 doesn't engage either. :mad: Almost positive that these two problems are related as they both occured right after fuel pump replacement. Any suggestions as to where to look?:screwy:

Thanks

Either take it back and have them check it or pop the hood and check vacuum lines and hoses.
May just be unpluged or broken vacuum line.
