1992 Buick Century 6 cyl Front Wheel Drive Automatic

Hey, my Buick recently has had trouble starting after being driven for periods of time. I have to pump the gas sometimes to get it to start while turning the key. It will eventually start, but then i smell gas after that. Also, lately when idling at a light or in a parking lot after being driven it will idle really low until it s about to shut off then pick back up, idle high and calm back down. This sometimes goes on for a while. It will even idle so low it sometimes shut off. I bought a fuel filter replacement but haven't installed it yet. What do you think the problem could be?

Has the check engine light come on? Also, have you checked fuel pump pressure? It sounds like you are losing the fuel prime.

Let me know.

My check engine light only comes on when the car ignition is in the on position, but never while driving. One time when the car was overheating the temp light came on while driving but it seemed odd. I have checked the alternator which is good, I have replaced a cracked hose on the fuel pressure requlator. I am not sure how I can check my fuel pump pressure. Also I do not know which wiring harness behind the passenger's side light bulb is for the fuel pump(if I may need to disconnect it). I think the problem is either the fuel pressure regulator which I cannot test because I don't have a pressure guage, the fuel pump or the fuel filter. Recently the car died on a turn and has been cutting off almost every time I drive and then change to park or reverse. In the mornings though it starts well and idls well, but soon it starts idling low and high and almost shuts off. When I pull up to lights now it idles up and down too.

Thank you for helping me out, I am trying to save some money in my last semester at Virginia Commonwealth University!!!

It is easy to check both the fuel pressure and the regulator. Here is a how to. Just watch the video and read the directions. Yes, you will need a gauge, but most parts stores will lend or rent them to you.

Give it a try and let me know what you find. If you have other questions, let me know.
