Stangnet Gurus,
When the fuel pump is going out does the car jerk when driving sometimes, this happened last week, I drove it 4 days later with no problems. I got off work this morning and the fuel pump was not working, it normally hums when turning on the switch, but it was quiet today. I had the stang towed to the house, after getting it home, the car fired right up about 4 times. I only had about 1/4 tank of gas, is it possible the pump was frozen, it got down to about 15 deg last night? I will replace the pump from a stock to a bigger if this should be changed. Please give advice.

My car did the same thing during the summer. The car would shake at slow speeds coming up to a stop. The fuel pump ended up going out. I went with a walbro 255lph and car runs 100 times better.

Fuel pump went out of my work van three days ago. I had to replace it in the parking lot. But it would shake and what not its last couple miles. But days before that the pump would stick and if I hit the gas tank the pump would un freeze. Did this a couple times, but other times started right back up. Sounds like yours is going to me.

Ya they said when they get old they heat up and start to cut out. Same thing happened to me over the summer.

I had one that would let the car start and drive but you couldnt give more than a 1/4 throttle or it would sputter and back fire. I put a fuel press gauge on it and it had 35 psi at idle but when you would rev it, the psi would drop until it ran out of fuel.......
