Bad Fuel Pump/Filter or what?

[onedivinehammer]

Anyone experience a bad fuel pump? Recently (this week) I'm having start-up issues. It would start okay in cool weather (morning/night) but then at the end of the work day or lunchtime the battery is dead (or so i thought.) Well I replaced the battery, and guess what, still having start-up issues. Weird thing is ... whenever I get a jump it starts up. But I've had a couple ppl say it sounds as if you're not getting any gas to the engine, either clogged filter, or bad fuel pump. But how would a jumpstart rectify an issue with the fuel pump? Make sense? I do have 98K on the car, and I do need to swap out plugs/wires but something's amiss.

I see that you have a '05 GT. Is it new to you? Or have you had it long? If so, when you fill the gas tank, did you wait until it was empty? IF so, maybe the fuel pump is going bad. I don't know why a jump start would then start the car. The fuel pump is in the gas tank, so that will have to be dropped to replace the pump.

Hooligan ... shouldn't you be outdoors enjoying the Indian or Banana Rivers? Anyways, it's an '03 GT I've had since day 1, 6 miles. Now has 98K. Go figure, but today it's giving me no troubles at all with start-ups; not last night, yesterday, or the day before. To answer your question, typically I fill the tank when I hit E-empty.

PS - Later this week I'm swapping out the plugs with NGK 2314's and the wires with probably Magnecor 8.5mm's. It definitely needs a tune up. Maybe that's hindering the start-ups.

Not a good thing to do all of the time. You should refill at 1/4 tank. The gas is what cools the fuel pump and at E the pump is not being adequately cooled. Replacing the fuel pump is spendy.

UPDATE:

Well, I went through the codes. I had a couple, but mainly it was p0340 & p0344 (camshaft position sensor issues.) So I swapped the CPS out and $50 later it seems to work. At the same time I swapped out the plugs, which I'm embarrassed to say were the original ones (98k), with NGK 2314, and the wires (again embarrassed to say the original ones) with Magnecor 8.5mm competition. The car is running great again! We'll keep an eye on it to see if the fuel pump is the problem. Typical fuel pump life is 100k.

PS - I did not get the Magnecor turbo edition wires. The only difference is that plug #4 (on the turbo) has a 90 degree angle going into the distribution cap. I had no issues with fit.

Well, when fuel pump doesn't deliver adequate pressure and volume to your engine, it may not run properly. Low fuel pressure can cause hard starting, a rough idle, misfiring, hesitation and stalling. No fuel pressure will prevent the engine from starting, or will cause the engine to quit running if the fuel pump fails while driving.

actually it's an ignition coil. and the cam sensor was going to be my suggestion. fuel pump is not a hard thing to do if you have the right support. and an empty enough tank. i'd say 1/4 tank would be low enough. qoute i got from my dealer was 300.00 installed. or depending on where you live this is something that can be tackled at a mod party. if your not already a member i'd suggest you head over to ptcrew.com. we have alot of gearheads with plenty of experience replacing just about every part on the car who would be willing to give you advise and even help you tackle such a project.
