1999 Ford E-Series Van won't start

[quote:3e42c4461e="amykaucic"]Electrical problem
1999 Ford E-Series Van V8 Two Wheel Drive Automatic 107000 miles

about 2 mos. ago, we replaced the battery and my son replaced the alternator; around 2 weeks ago the van wouldn't start unless you pumped the gas pedal; then it wouldn't start unless it was jumped; the jump from the other vehicle was probably no more than a minute at the most;
I am very frustrated since we depend on this vehicle for getting kids to school & me finding a job
Please help!
Thank you[/quote:3e42c4461e]

Pumping the gas pedal does nothing with a fuel injected engine, as there's no mechanical fuel pump to squirt fuel into the engine. Check / clean all electrical connections, starting @ the battery terminals & starter.
