I have a 1995 jeep sport it crank but wont turn a lot of people tell it could be fuel pump it could I really dont know it I need answers
If it cranks at normal speed, it could be the fuel pump or loss of spark. Autozone has a loan-a-tool policy. Pretty sure you can borrow or rent a fuel pressure gauge to see how good your pump and fuel filter is. Just hook it up to the test port on the engine's fuel rail, and turn the key to on, not start. It should immediately show about 40 pounds of pressure- 40 psi. If it is good, then it is probably an ignition problem, and you need to check for spark on a spark plug wire.
If the test shows no pressure, then the pump may be bad. It is not turning on, for sure. A final check before replacing the pump is to check that the pump power wire at the fuel tank connector has power on it with the engine cranking over. If it has power there when cranking, the pump circuit is good (all fuses and relays good). The fuel pump itself is the problem.
On that model jeep, if it is a Cherokee Sport like my son's '95 jeep, it is quite easy to change out a fuel pump. You don't have to drop the gas tank to replace the pump. The assembly goes into the gas tank at the front upper part of the tank, above and just back of the rear differential. I changed out the fuel pump on his jeep in a K-mart parking lot in a little under 2 hours. Wiggling and twisting the assembly out of the gas tank hole for removal was the most time consuming part. It was really quite easy. If you have ever replaced a pump before, .the jeep is a breeze.
