OLDSMOBILE ALERO BACKFIRE PROBLEM

2001 Oldsmobile Alero • 144 miles

Car will turn over but will not start, new fuel pump, filter, backfires thru the intake, will only start by holding gas to floor and turning the key, it will backfire thru intake and start up, running very rough, like only 2 plugs are firing.

Check fuel pressure to make sure it is within spec. Check plugs for tune up.
