Car fueling and starting issue

My wife has a 2004 Jeep Grand Cherokee 4x4 4.7L. When you go to the pump to fuel it up, you have to fill it extremely slow. If you fully squeeze the pump, you can get maybe 1-2 gallons in before the pump shuts off or shoots fuel out. Any idea on that?

Second, when she gets in to start the vehicle, she has to turn the key forward about three times (basically allowing the fuel pump to dump more fuel) before it finally starts. Does this mean the fuel pump is going out or bad fuel filter, injectors? I'm clueless where to start.

hey husker, you'll get a much better response posting this in the WJ section...

I drive a TJ so take it with a grain of salt, but later TJs have a problem with the fuel spout, except the opposite, i.e. NOT shutting off I would suggest next time instead of jamming the filler all the way down, pulling it back a notch...or vice-versa if it has been not going all the way in, jam it down. Sometimes it seems like there is a sweet spot that you have to hit.

The second issue sounds like what I think is called the check valve. Regardless what it is called, it holds fuel in the system, so that the pump does not have to prime the lines every time. If it is a slow leak, you may notice that after only a short period of engine off, it might fire right back up on the first try, whereas overnight you have to prime it. In the meantime, she probably doesn't need to turn the key repeatedly, but turn it once for 3 seconds, then try to crank it.

That's all I can tell you - repost in WJ and I'm sure you'll get a lot better help/details on your problems.
Can you afford the car? Have I provided you all the information you need on the car? Do you like the car? Then buy the car.

Is there something in your fuel tank? Sounds like when you fill up fuel is hitting the nozzle and it thinks that you car is full.
