1999 Saturn SC1 DOHC, I recently had my car serviced, they did the fuel injection service, they replaced the fuel filter, it ran for a few miles, then the problems started. The car was hard to start, like there was no fuel, When I took off from a traffic light the car died (didn't stall) just moved like at idle. Then the "check engine" light came on. This continued til I got home. I looked up the code (P0171), I replaced the whole Fuel pump assembly. The problem is still there but not as bad, hard to start and only dies (dosen't stall) when taking off from a light sometimes. I think it has the wrong fuel filter (G9370) and should be (5G1316) am I NUTZ?

What were the symtoms before you had the work done? P0171 is running too lean, not enough gas! Or too much air. You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs!
As for the filter, if it's the same brand, then it could be a problem! If its a different brand it might be the right one.

The car ran great, my wife took the car in to get an oil change, they talked her into fuel injector service.
I don't know what type fuel filter/regulator the car had my guess it is OEM.
The codes I'm reading now are, P0133, P0171, P0404, P0300, and an old code P1651 that I fixed 1 year ago.
Thanks for your help

G9370 is a fram number and is correct for that.

Like Merlin said sounds like a possible vacuum leak.

The one I would worry the most about is the P1651 thats a PCM quad driver, or cooling fan relay, 404 is the EGR and 133 is slow response on 02 sensor bank 1 sensor 1.171 is too lean bank 1. These guys may also have removed a connector and forgot to replace it. Look for a disconnected injector. Or two. See also if they plugged the pressure regulator's vacuum hose back in!

After days of checking this and that, purchasing test equipment, software that didn't help (all in all out about 650.00 to 700.00). Turns out it was the first thing I thought the Fuel Filter/Regulator.
The fuel pump was pumping fuel back into the tank instead of pumping it into the injectors.
As for re-embursement for the fuel filter, NO ABLA ENGLISH!
