Question about 1997 Pontiac Grand Am
So my fuel pump does turn on when you turn the ignition to the on position. It is clear my fuel filter needs changed. But something tells me that won't start the car. I changed my spark plugs bout a month ago. I did just put fuel injector cleaner in the tank for the first time. But I did it the correct way and put more gas in after putting it in. So we are not sure what is wrong. Also it does appear that my crossover is leaking. I had a leak at the water valve. We changed that and apparently it made the cross over bust or come loose something. All it was was water tho .it had been leaking for awhile. I had just been making sure the over full was full of water before I would drive it any where. Not sure if that is important to the problem or not
Lets start at the beginning. Are you getting spark to the plugs, and do you have normal fuel pressure at the injector rail ?

When was the last time spark plugs and wires where done? That could be a possible cause, also check the timing through the distrubotor cap.
Hope this helps

SOURCE: Acceleration is jerky (tardy).
After removing ther filter, pour it's contents into a glass jar. dirt/rust will be obvious...Water is heavier than gasoline and will collect at the bottom of the jar and form a visible sepearte "level" or layer. If you find either, the tank needs to be cleaned out. As per your question, this situation dod not happen 'till you serviced it. Therefore it is likely to begin looking at what was just done, before looking at something new. Since synthetic oil has nothing different in it that the engine would respond to, I would not look to that as a problem (unless while working, you accidentally pulled a connector or vacuum hose off.
I too do this for free, I work from what's inside my head, only referring to manuals as a last resort. When I don't know something, I either don't answer or put the issue aside and do a bit of research. There is a "pay side" on FixYa, but anyone relying on that for income is insane...just not enough traffic there. The benefit I get by doing this is to keep my mind working and give assistance to people who otherwise would hav little or no info or help. I enjoy getting a good rating but that is not my primary goal...Getting you running is! I won't comment on that further.
Now let's try to get this puppy fixed!!!

There are a few other things taht could be causing fuel starvation. First of all, did you pull the injectors and clean out the individual filters? There are small, conical screens inside the top of each injector, and they could be clogged. Second, There could be some carbon build-up on the intake valves, which would act like a sponge for the fuel after initial start-up. A can of BG44K fuel system cleaner from NAPA will get rid of that. If it is neither of these, the fuel pressure regulator could be leaking. Other than this, the car would need to be diagnosed by a shop before action is taken. I hope this helps you!

Testimonial: "I ended up taking the car to a local shop for diagnosis. It turns out that the fuel pump is week and not supplying enough pressure to the motor. "
