While driving down the road my pontiac sunfire SE 2.2 down the road i noticed that the DRL light was flashing so i turned around and went home to check it out when i got home i tryied to turn the car over again to see it it did it again this time i got a really fast beeping sound and it would not turn over. after i got out of the car i relized that my fuel pump was still running so i very quickly disconected my battory. after reconecting it the fuel pump was off and the car started it started for about three times and then went back to what it was doing in the first place any ideas on what it might be? help please
My guess would be either a sticking relay or a faulty ignition switch.
Suggestions: loose/corroded connection between the fuel pump and the computer; short between the fuel pump and computer; computer firmware needs to be reset.

Its likely that you have either a bad ignition switch or a bad neutral safety switch (if stickshift, clutch switch) Try starting in neutral...if it starts, change neutral switch (jump across clutch switch, check starting in neutral with your foot on the brake) Ignition switch is on top of steering column under dash.

Crank position sensor bad?
Are you sure the fuel pump is working? Might be the sending unit in the fuel pump that is bad. Clogged lines, clogged fuel injectors, clogged fuel filter, all things that could be checked.

Starter solenoid , or wire that leads to it.
Also , if standard transmission , may be the switch on clutch pedal is intermitant.
Engine won't turn over unless it thinks you have your foot on the clutch.

Your, car has a crankshaft sensor that, may not working.
Check, the sensor, it is located ( Near the Crankshaft,) You'll
need to look from under the car.
Or It may just NOT have a good connection.
Wet, DIRT bad connection rust on connector.
hope it helps
