Fuel problem - Please Help

When an electric fuel pump starts to go out, will it still pump fuel? Today I was driving down the interstate around 60-70mph and my jeep started to cut out like it wasn't getting enough fuel. So I stopped to see if it would idle and it did with no problems. So I tried to take off again and as soon as I put my foot in it, it would cut out and die. What gets me is it would start and idle no problem every time. I was only able to drive about 25-30mph, but when driving up hill it would cut out. I did this for the next 45 miles until I got home. Thanks a million.

 

I have the clear filter and it's clean. I just started it again and could see the fuel flow into the filter. Could it be something else? I just have no clue...it has me stumped.

 

ound like a filter to me a well, I had ther ame problem and it was the filter

 

The fuel cell, sender, lines, and filter are less than a year old. I did look at the filter and it is very clean...no dirt at all. The fuel pump is around 4yrs. Is it possible to pump fuel at idle with no problems then not be able to deliver enough fuel when accelerating? Maybe a hole in the diaphram...I just don't know

 

I agree with the fuel problem, but maybe it's time to replace your coil also just for fun.

 

a fuel filter is very cheap. Perhaps there is a defect in what you have, or it can clog and visually look OK.

That's where I'd go first - and it wouldn't make any difference to me if I had replaced the fuel filter a month ago -

 

Thanks for all the help. It turned out to be a bad ground. When I was installing my power steering i cut part of the grounding strap (motor to chasis) and forgot to replace it. I replaced it today and it worked like a champ. Thanks again.

 

Check all of your flexible fuel lines...if you have the smallest of cracks, it will suck air in when you step on it and you will get the results you report. This happened to me with a '71 I had. I replaced all the flexible lines and it ran like a top. KCJ
