I have a 95 Jeep Grand Cherokee that I traded in on the c4c deal. I have not yet taken delivery (they are waiting for the gov't $) and my Jeep died a couple of nights ago, it was running, I stopped, parked, ran into a store, came out to restart, it sputtered and choked then died. It tries to start but won't turn over. After a tow and many tests, my mechanic says it is the fuel pump - he's getting 0 pressure from it, although the wires show power. He tried banging on the tank to jolt it for "one last start", but to no avail. We have looked at the Bosch fuel pump, but mechanic says that he has not ever replaced just the pump in these, mfg sells the whole unit (for 3x the price) and I am wondering if it is possible to replace just the pump inside the sending unit without breaking the whole thing. Thanks for any help you can provide
