CAR WONT START

2000 Pontiac Bonneville • 156,000 miles

Car turns over but will not stay running. It starts just for a second. I replaced ignition switch. The fuel pump runs. Fuel pressure is 40psi then rises when it kicks over but maintains at 40. What next?

Check to make sure you're not losing spark when it starts. You could have a bad crank sensor. Also, let me know what size engine you have so I can confirm the fuel pressure. That may be low, but I would think it is enough to keep it running.
