May 1 (Reuters) - U.S. stock index futures were higher on Friday ahead of the release of data that could support signs that the economy is regaining momentum after stumbling in the first quarter.
* Construction spending is expected to have risen in March after slipping in February, while the Institute for Supply Management's manufacturing index is expected to have increased in April from March. Both numbers are expected at 10:00 a.m. EDT (1400 GMT)
* Automakers are expected to report that sales moderated in April after rising the previous month. The data is due at 13:30 p.m. (1730 GMT)
