1999 Pontiac Grand Am: fuel pump failure

Filed Jul 16, 2012 · Engine · SD

My husband and I had just made it into the city after a 1 and a half hour drive. After driving around town for about an hour our car, 99 pontiac grand am, shut off. We sat for a bit and tried it and it started right up. But it kept doing it several different times throughout the day. We thought it overheated but the temperature gauge read 200 degrees. He changed both o2 sensors, cam shaft, alternator, water pump, put on a used fuel pump. We were thinking that it might be the fuel pump, but are unsure. The possible problems we have came up with are the fuel pump since it's used, the cadillac converter because it smells bad at times, like when we go up hill, or as I was reading all the problems people were having with there 99 pontiac grand am vehicles, would be the intake gasket or the ABS light that goes off and comes on when it feels like it. I have spent alot of money trying to figure out what is wrong with this car and I need help.

I have owned this car for just under 4 years and have spent the last 2.5 in and out of the service dept. With it. I've had the brake rotors replaced 3 times, every year, almost to the day. I have also just had the fuel pump replaced 2 times and discovered a leak in my intake manifold with only 41k miles on the vehicle. It has been a safety hazard at times and left me stranded once.

In approximately march of 2000 the vehicle first stalled while driving in city traffic going approximately 35 MPH. Was able to restart car and proceeded to dealer service dept. To have car checked out. They proceeded to install a breather valve they felt was faulty. Approximately 3-4 days later, the vehicle stalled again. On the way to the dealer it stalled 3 more times in a matter of 2 miles. They diagnosed the problem as being a faulty fuel pump. Today, august 17, 2000 the vehicle stalled again as I pulled into our driveway after having driven 300 miles. Experienced exact same symptoms as the first time the pump failed. Will be contacting dealer first thing friday a.m. To confirm problem. Of course, vehicle is no longer under warranty but will demand to be repaired at no charge.
