NEW YORK, Oct 1 (Reuters) - U.S. stock index futures fell on Thursday, with investors consolidating gains after a strong quarter, and as a raft of economic data was due that could offer clues about the tone of economic recovery.
With the Dow Jones industrial average up 15 percent in the third quarter, Thursday's indicators, notably September manufacturing and weekly jobless claims, will be crucial in determining the validity of the rally.
"We came off the third quarter with solid gains ... and now that we are in a new month, a new quarter, I expect some sort of a pullback as investors are ready to scrutinize economic indicators today after some disappointing ones yesterday," said Peter Cardillo, chief market economist at Avalon Partners in New York.
The data include pending home sales and personal income and consumption for August, and may offer fresh evidence on the strength of the U.S. recovery, ahead of Friday's non-farm payrolls numbers.
Economists expect the Institute of Supply Management manufacturing reading to climb to 54.0 for September from 52.9 in August, according to a Reuters survey. Pending home sales are seen rising 1 percent in August compared with a 3.2 percent increase in the previous month. The numbers are due at 10:00 a.m. (1400 GMT).
A total of 530,000 new filings for jobless claims, the same as the previous week, is forecast by economists. The data is set for release at 8:30 a.m. (1230 GMT).

U.S. stocks fell on Wednesday after a surprising contraction in the Institute for Supply Management-Chicago's business barometer, indicating weakening business activity in the regional economy.
Still, the Dow marked its best quarterly performance since the fourth quarter of 1998, while the S&P 500 notched its second straight quarterly advance of 15 percent. The Nasdaq gained 15.7 percent for the third quarter. (Reporting by Angela Moon; Editing by Padraic Cassidy)
