Fuel system problem w/98 Cherokee

I have a 98 Jeep Cherokee 4.0 liter. I have replaced the fuel pump twice in the last 2 weeks. The second one came from the Jeep dealer with the thought that the after market pump was faulty. I still have the same problem which is - it takes 2 or 3 times to start (getting the fuel into the system). We checked it with a pressure regulator and when I turn the key to the start position then off 3 times, it builds up enough pressure to start the first time I crank it. The problem can't be the fuel pump, there's no inline fuel filter that I'm aware of. Any ideas?

Thanks,
Jim

Why do you have to crank it three times to build up pressure? Something sounds wrong there....start here.

I don't crank it 3 times. But it does take 3 times turning the ignition to the start position (which sends fuel from the tank) to get it to start.

Right. But why? Each time you turn the key forward, the fuel pump should energize and there should be enough pressure to start the truck.

I still think there is a fuel pressure issue here.

I am having a similar problem and have yet to try any sort of repair. We actually have 2 problems if anyone has insight.

1) Starting Problem: Takes 1 really long turn of the ignition or 2 shorter turns to get the car started

2) Stalling Problem: Car will stall on left turns when the fuel is low.

I am not that upset by the stalling problem as it can be fixed by keeping more fuel in the tank. The other problem however signifies a greater problem to me. plus this problem came on rather suddenly and the last thing I want is for my wife to call me upset and stranded. Anyone have any input?
