Re: 97 flt codes P0171 & P0140 w/ 30 psi fuel pressure

didn't jump 10-15, but went up to 40 with key on and 43 with engine running. In any event, I'm not concerned as long as it is no longer throwing codes and I can get thru emissions next time. Need to get some mileage out of the new tires. I do have a spare fpr I pulled from the junk yard, just in ...

Re: 97 flt codes P0171 & P0140 w/ 30 psi fuel pressure

Been a while, wife kept putting gas in the car... Changed out the fuel pump yesterday and no more p0171 faults. Fuel pressure is 35 with key on and car running. Hope my mpg doesn't tank.

Never looked for a write up on changing the fuel pump. I pulled both rear tires and loosened up the emerg brake ...

Re: 97 flt codes P0171 & P0140 w/ 30 psi fuel pressure

Hope my fuel mileage doesn't drop too. I just ordered a spectra sending unit from Advance auto with a $50 off $125 coupon (DOW36) that expires today. Yes, I'm a cheap bastage. A buddy has a contact that is getting me an gm fuel pump for $65 but their sending unit was $200 plus... I'll get the ...

Re: 97 flt codes P0171 & P0140 w/ 30 psi fuel pressure

So here's something to make you smile. I relieved the fuel pressure when I was checking my fuel pressure regulator the first time, took out the clip, and turned around to get something and pop, bang, booey, it shot out hit the hood of the car and I couldn't find the larger o-ring. Got the air ...

Re: 97 flt codes P0171 & P0140 w/ 30 psi fuel pressure

Thanks for the feedback!! One more question - since my gas gauge isn't working should I order a complete assembly or just the pump. Not sure what the problem might be since the gas gauge has never worked since I owned the car.

RockAuto has the Delphi pump only for 66.76 and a Spectra assy for 122 ...

97 flt codes P0171 & P0140 w/ 30 psi fuel pressure

Hey guys, looking for some expert advice before I go throwing any more money at this beast. I've only got 30 psi with the car running, only had 20 with the key in the 'on' position. Picked up a fuel pressure regulator from the local jy and still have 30 psi and throwing P0171 and P0140 flt codes. I ...
